Support & Troubleshooting

A "No Signal" message means the display isn’t receiving a valid video signal from the source. This can be caused by several factors, such as incorrect input selection, incompatible video settings, a defective connector, issues in the signal chain, or faulty cabling. Depending on the setup, multiple components (switches, converters, extenders) may be involved, so it’s important to systematically check where the interruption occurs.

By following the steps below in order, the problem can usually be located and resolved quickly and efficiently.

1. Check the Input Selection

• Make sure the correct input is selected on the display.
• An incorrect input selection is a common cause of “no signal”.
• In environments with multiple sources or matrix switches, the input may have changed unnoticed.

2. Check the Source Settings

• Confirm that the source is active and outputting a signal. If necessary, test this on another display.
• Check the output settings: resolution, refresh rate, and signal format must match the supported specifications of the Beetronics display.
• Incorrect settings, such as choosing a resolution that is too high or a frequency the display does not support, will result in an immediate loss of signal.

3. Inspect the Signal Chain

• Map the complete route from source to display: directly or via splitters, converters or extenders.
• Connect the source directly to the display to rule out external devices.
• Check whether any adapters or converters used are compatible with the desired signal type (for example, digital-to-analog conversion requires an active converter).
• Note for USB-C: both the source and the cable must support DisplayPort Alt Mode. Not every USB-C port or cable is suitable for video transmission.

4. Check Wiring and Connections

• Ensure all cables are connected correctly and securely.
• Please note the maximum cable length for the signal type being used. Excessive cable length or poor cable quality can lead to loss or instability. An overview of the maximum recommended cable lengths per connection can be found here.
• Test with an alternate cable to rule out cable defects.

5. Perform Exclusion Steps

• Test the display with a different source.
• Test the source on another display.
• If available, use an alternative input port.

6. Restart and Handshake

• After all connections have been checked, restart both the source and the display.
• With digital connections (such as HDMI or DisplayPort), a new handshake may be required to properly initialize the signal.

An incomplete or cropped image is usually caused by a mismatch between the source’s resolution or aspect ratio and the display’s native resolution and aspect ratio. Overscan functions in the operating system, graphics card, or the display’s OSD menu can also cause this issue. For optimal performance, the source’s output signal should exactly match the display’s native resolution and aspect ratio without additional scaling. Incorrect settings can result in cropped edges, black bars, or distorted content.

1. Check Resolution and Frequency

• Open the source’s display settings and select the Beetronics display.
• Set the resolution to the native resolution (see datasheet or product specifications).
• Check if the refresh rate (Hz) selected on the source is supported by the display.

2. Check Scaling and Aspect Ratio

• Turn off scaling or zoom in the operating system, or set it to 100%.
• Check your graphics card settings (NVIDIA, AMD, Intel) and disable profiles such as overscan or custom scaling.
• In the OSD menu, ensure the aspect ratio is set to Just Scan for pixel-to-pixel display.
• Disable manual sharpness or picture modes in the OSD that affect the image.

3. Inspect the Signal Chain

• Use a direct connection whenever possible, without splitters, converters, or extenders.
• Check whether cables or adapters support the resolution and frequency.
• Be mindful of maximum cable lengths as longer or lower-quality cables can cause signal degradation.
• Note: Some matrix switches, KVMs, or video extenders automatically apply scaling or overscan. Check their settings and, if possible, set them to passthrough for native resolution.
• If possible, test with an alternative cable or source.

A blurry or fuzzy display is usually caused by a mismatch between the source’s resolution and the display’s native resolution, or by signal degradation within the video chain. Incorrect scaling settings in the operating system, graphics card, or the display’s OSD menu can also reduce sharpness. For best results, the source’s output signal should exactly match the display’s native resolution without additional scaling. Incorrect settings can cause interpolation, distortion, or loss of detail.

1. Check Resolution and Frequency

• Open the source’s display settings and select the Beetronics display.
• Set the resolution to the native resolution (see datasheet or product specifications).
• Check if the refresh rate (Hz) selected on the source is supported by the display.

2. Check Scaling and Aspect Ratio

• Turn off scaling or zoom in the operating system, or set it to 100%.
• Check your graphics card settings (NVIDIA, AMD, Intel) and disable profiles such as overscan or custom scaling.
• In the OSD menu, ensure the aspect ratio is set to Just Scan for pixel-to-pixel display.
• Disable manual sharpness or picture modes in the OSD that affect the image.

3. Inspect the Signal Chain

• Use a direct connection whenever possible, without splitters, converters, or extenders.
• Check whether cables or adapters support the resolution and frequency.
• Be mindful of maximum cable lengths as longer or lower-quality cables can cause signal degradation.
• If possible, test with an alternative cable or source.

Beetronics displays support both portrait and landscape orientations. A Beetronics display does not automatically rotate like a tablet or smartphone. The orientation is determined entirely by the video signal or file output from the source. For the content to display properly, the video source must output the desired resolution and orientation (portrait or landscape).

1. Check the Source Configuration

• In the operating system or graphics settings, select the desired orientation (portrait or landscape).
• Ensure the output matches the display’s native resolution exactly. Different resolutions can cause scaling, interpolation, or distortion.
• Check whether the selected refresh rate (Hz) is supported by the display.

2. Check Content and Layout

• Confirm that video files (for USB playback) were actually exported or recorded in portrait mode. A landscape file played in portrait mode will always produce black bars or distortion.
• Verify that image files have the same pixel aspect ratio as the display (for example, 1080×1920 for portrait or 1920×1080 for landscape). Deviating proportions cause interpolation or distortion.
• For presentations or digital signage, make sure the source program (e.g., PowerPoint, CMS, or media player) is set to the correct orientation before displaying content.

3. Check Graphics Card Settings

• In the NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Command Center, ensure overscan and custom scaling are disabled.
• Set the scaling mode to No Scaling or Preserve Aspect Ratio to ensure full pixel rendering.

4. Check the Display’s OSD Settings

• Confirm that the aspect ratio in the OSD menu is set to Just Scan. This is the default setting on all Beetronics displays and guarantees 1:1 pixel mapping without overscan or edge clipping.
• Check that there are no additional picture modes or filters active in the OSD that affect the display.

5. Inspect the Signal Chain

• Use a direct connection whenever possible, without splitters, converters, or extenders that might alter orientation or resolution.
• Verify that all devices in use (such as a media player, signage controller, or KVM switch) transmit the correct orientation and resolution. Some systems automatically apply scaling or rotation.
• If possible, test with an alternative cable or direct connection to rule out external factors.

If the touchscreen is completely unresponsive, the USB connection between the source and display may not be recognized. Beetronics touchscreens use PCAP technology and communicate via HID (Human Interface Device) over USB. The absence of a touch signal can be caused by incorrect wiring, insufficient USB port support, an unsupported operating system, or a problem with HID device detection.

Always check first whether your operating system and hardware combination are officially supported. If basic compatibility is lacking, further troubleshooting will not be effective.

1. Check Operating System Support

• Beetronics touchscreens are recognized by default via HID in Windows, macOS (with the UPDD driver), Linux, ChromeOS, BrightSign, and Samsung DeX.
• Older systems (such as Windows 7 or early Linux distributions) may require additional drivers or configuration.
• Unsupported or embedded systems without HID support will not provide touch functionality.

2. Check the Wiring

• Use only the supplied cables: USB-C to USB-C or USB-C to USB-A.
• Ensure the cable is connected correctly and securely to both the source and the display.
• If possible, test with the second supplied cable to rule out a cable defect.

3. Check the Source USB Port

• Not all USB-C ports support DisplayPort Alt Mode and USB data. Check the device specifications.
• When using USB-A, make sure the port supports data transfer as some ports only supply power.
• Be careful with docking stations and hubs: multiple devices often share the same controller, which can cause recognition failures or insufficient bandwidth.

4. Check Input Selection and Video Source

• When using the USB-C to USB-C cable, a single cable can provide video, audio, and touch. Check that the port on the source device supports this.
• When using the USB-C to USB-A cable, video is transmitted via HDMI, DisplayPort, or VGA, while touch is delivered via USB-A. Ensure the correct video input is selected on the display.

5. Check Whether the Operating System Recognizes the Touchscreen

• Windows: Open Device Manager and check if the touchscreen appears under HID devices.
• macOS: Go to System Report → USB to verify that the touchscreen is listed.
• Linux: Use lsusb of xinput list to confirm that the HID device is detected. Restart both the source and the display with the USB cable connected.

6. Rule Out Other Causes

• Test the display with another source to rule out incompatibility or a defective port.
• Test the source with another USB touchscreen to verify that the source’s USB function is working correctly.

Common Causes

• Using USB-C cables intended only for charging, without data support
• USB-C ports without Alt Mode or with limited data capability
• USB-A ports that provide power only (no data)
• Docking stations or hubs with insufficient bandwidth or power for touch input
• Outdated or unsupported operating systems.

A failing or unstable touch connection is almost always caused by interruptions in the USB data chain or by power-saving settings that disable the source’s USB port. The touch layer of Beetronics displays is fully powered and controlled by the 5V USB connection (USB-A or USB-C). If power or data communication is interrupted at any time, touch functionality is immediately lost.

By systematically going through the steps below, the cause can be quickly identified and resolved.

1. Check the Physical Connection

• Check that the USB cable is securely connected to both the source and the display.
• Avoid loose connections or adapters that introduce extra movement or instability.
• Use the included cables (USB-C to USB-C or USB-C to USB-A) whenever possible. Not all cables support stable HID communication.

2. Check Cable Length and Signal Quality

• Be aware of the maximum recommended lengths for USB 2.0 and USB 3.0.
• Avoid passive extension cables or hubs, as these often cause voltage drops or signal interruptions.
• Use active extenders or USB-over-Ethernet solutions if longer distances are required.
• Ensure the source provides a stable 5V power supply via the USB port. Some sources (e.g., laptops, thin clients, USB hubs, or embedded systems) may not supply enough power, causing the touch layer to disconnect.
• Keep in mind that multiple USB devices connected to the same power source can exceed the maximum current capacity. Even if a single port provides enough power in theory, total load can cause instability. In that case, a powered USB hub or direct connection may resolve the issue.

3. Check Power Management and System Settings

• Disable USB selective suspend (Windows) or similar power-saving features in your operating system, as these can temporarily turn off USB ports when active.
• In Device Manager (Windows), check whether the USB Root Hub has any power management options that allow the device to turn off.
• On macOS and Linux, confirm that power-saving features do not automatically disable USB ports.

4. Inspect the Signal Chain

• Connect the touchscreen directly to the source to eliminate any issues with hubs, KVM switches, or docking stations.
• Test with a different USB port to rule out port-specific limitations or defects.
• When using USB-C, verify that both the port and the cable support USB data (HID), not just power or video.

5. Test Alternative Configurations

• Test the touchscreen with a different cable.
• Test with a different source to determine if the problem is with the display or the source.
• Reboot both the display and the source to reinitialize the USB handshake.

1. Check Resolution and Display Settings

• Make sure the source is driving the display at its native resolution (see datasheet or product specifications).
• Different resolutions cause interpolation, meaning the touch layer no longer aligns exactly with the screen’s pixel mapping.
• Check that the refresh rate (Hz) is supported by both the source and the display as unsupported rates can cause lag or stuttering.

2. Check the Calibration

• Windows
  • Open Control Panel → Hardware and Sound → Tablet PC Settings.
  • Click on Calibrate → Touch input.
  • Select the correct screen (in multi-monitor setups the wrong screen is often selected by default).
  • Tap the displayed calibration points as precisely as possible.
  • Save the settings and restart the application or session.
  • Please note: When the resolution is changed, the calibration must be performed again.
• macOS (via UPDD Driver)
  • Install and open the UPDD Console.
  • Go to the Calibration tab and start the procedure.
  • Calibrate according to the on-screen instructions and confirm.
  • In the UPDD settings, verify that the touch input is assigned to the correct display.
  • For multiple screens, use the Assign function in the UPDD Console to create the correct connection between touch layer and display.
• Linux
  • Check if the HID touch input is recognized correctly with xinput list.
  • Use xinput_calibrator or configure libinput to set the correct mapping.
  • For screen rotation or unusual setups, manually adjust the Coordinate Transformation Matrix.
  • Make the settings persistent by adding the configuration to /etc/X11/xorg.conf.d/ or the relevant udev rule file.
  • Please note: On some distributions (e.g. Ubuntu with Wayland) it may be necessary to confirm the display assignment separately via Gnome or KDE settings.
• Multi-Monitor Setups
  • Confirm that the touch layer is explicitly assigned to the correct display. A common issue is that touch input is registered on the wrong screen.
  • Windows: Use Tablet PC Settings → Setup to assign the input to the correct display using on-screen prompts.
  • macOS: In the UPDD Console, assign the controller to the correct display.
  • Linux: Use xinput map-to-output to explicitly link the touch input to a specific monitor (e.g. HDMI-1 or DP-2).

3. Check USB Connection and Power

• Connect the touchscreen directly to the source without hubs or extension cables.
• Please note the maximum cable length: 5m for USB 2.0 or 3m for USB 3.0. For longer distances, use active extenders or powered hubs.
• Confirm that the USB port supplies a stable 5V power source. Voltage fluctuations or drops below the minimum threshold can cause lag and inaccurate response.
• Please note that multiple USB devices connected to the same source may collectively exceed power capacity, even if an individual port theoretically provides enough power.

4. Check System Settings and Drivers

• Disable any power management features that may put USB ports to sleep.
• Confirm that the correct drivers are installed (e.g., UPDD on macOS). Outdated or incorrect drivers can cause latency.
• On Windows: Check Device Manager for conflicts under Human Interface Devices (HID).

5. Avoid Interference and External Factors

• Keep magnetic or highly conductive objects away from the touchscreen surface, as they can interfere with capacitive touch detection.
• If possible, test the touchscreen in a different environment to rule out sources of electromagnetic interference (EMI).

6. Test Alternative Configurations

• Test with a different source (such as a PC or media player) to rule out source-related limitations.
• Test with an alternate USB cable or a different USB port.
• Reboot both the display and the source to re-establish the USB handshake.

When using a Beetronics touchscreen in a multi-monitor setup, the touch input may not correspond to the correct screen. For example, touches on the Beetronics display might register on another connected screen, or the touch position may be offset. This occurs when the operating system does not automatically pair the touch controller with the correct monitor.

1. Check the Resolution and Layout

• Make sure all connected displays are running at their native resolution. Different resolutions can disrupt the touch input mapping.
• In the operating system’s display settings, confirm that the screen layout (left, right, top, bottom) matches the physical arrangement of the monitors.

2. Windows

• Open Control Panel → Hardware and Sound → Tablet PC Settings.
• Click on Setup and follow the prompts to pair the correct screen with the touch controller.
• If necessary, perform a new calibration afterwards via Calibrate.
• Please note, if the screen order or resolutions change, the touch assignment will need to be reconfirmed.

3. macOS (UPDD Driver)

• Open the UPDD Console.
• Go to Assign and select the correct connection between the Beetronics touchscreen and the display.
• Then perform a calibration via the Calibration tab.
• For multiple touchscreens, explicitly assign each controller to the correct display to avoid conflicts.

4. Linux

• Check the list of available touch devices via xinput list. Map the touch input to the correct display using the command: xinput map-to-output <device-id> <output>
• Where <device-id> is the HID touch controller and <output> is the display name (for example, HDMI-1 or DP-2).
• Make the mapping persistent by saving it in /etc/X11/xorg.conf.d/ or by adding it to a startup script.
• When using Wayland, check whether your desktop environment (GNOME or KDE) supports native input mapping settings.

5. Other Points of Interest

• When using USB extenders, docking stations, or hubs, the enumeration of USB devices may change, requiring the pairing to be reset.
• Make sure all cables are connected correctly and that only one active touch controller is connected to each display. Multiple touch devices connected to the same source can cause conflicts.

Beetronics displays are supplied with a power adapter that includes a standard 2-meter cable. For video, audio, and data connections, maximum cable lengths depend on the resolution, refresh rate, and cable type. For longer distances, active solutions such as extenders, boosters, or optical cables may be necessary.

• HDMI: Up to 10 m (beyond that, only with an active HDMI extender)
• DisplayPort: 3–5 m, depending on resolution (maximum 3 m at 4K@60Hz)
• VGA: Up to 15 m (analog signals lose quality over distance)
• RCA (video): Up to 50 m
• BNC (video): Up to 100 m (professional CCTV/broadcast coax)
• 3.5 mm audio (in/out): Up to 5 m with standard cables; for longer distances, shielded cables or active audio solutions are recommended
• USB-C: Maximum 3 m with passive cables (USB 3.1 and DisplayPort Alt Mode). Beetronics includes a 2 m cable as standard.
• USB-C → USB-A: Up to 3 m according to the USB 2.0 specification. Beetronics includes a 2 m cable as standard.
• USB-A → USB-A: Up to 3 m according to the USB 2.0 specification. Beetronics includes a 2 m cable as standard.

Beetronics touchscreens use USB-C for video, audio, and touch. Proper operation depends on the source device, the cable used, and any combination with video ports. Two cables (USB-C to USB-C and USB-C to USB-A) are included with every Beetronics touchscreen to ensure compatibility.

1. Support from the Source

• Check if the USB-C port on the source device supports DisplayPort Alt Mode and USB data.
• Not all USB-C ports can transmit video and touch; some only support charging or data.

2. USB-C to USB-C Cable

• Depending on the source, this cable can provide video, audio, and touch through a single connection.
• Both the source and the cable must support Alt Mode and USB data; if either is missing, some functionality will not work.
• Always use a certified cable and stay within the recommended cable lengths to avoid signal loss.

3. USB-C to USB-A Cable

• This cable only provides touch functionality.
• For video and audio, one of the video ports (HDMI, DisplayPort, VGA, BNC, or RCA) must be connected simultaneously.
• This configuration is recommended when the source does not have a full-featured USB-C port with Alt Mode.

4. Common Problems

• No touch function: Often caused by using a charging-only or data-only USB-C cable.
• Image but no touch: The source’s USB-C port does not support USB data. Use the USB-C to USB-A cable in combination with video via HDMI or DisplayPort.
• Unstable operation or failure: May indicate excessively long or uncertified cables. Test with the supplied cables to rule out defective cables or incompatibility.

5. Recommended Practice

• Always use the supplied cables as a starting point for installation.
• If a longer cable is necessary, check that it is certified for Alt Mode and data.
• If you experience any issues, first test with the standard cables to isolate source or configuration errors.

Beetronics displays are equipped with integrated speakers. Depending on the model, 3.5 mm audio inputs and outputs may also be available.

Consult your model’s datasheet for the exact audio connections, as these may vary by product line.

Digital video ports (HDMI, DisplayPort, USB-C) support both video and audio, while analog video ports (VGA, RCA, BNC) transmit video only. In those cases, audio must be connected separately via the 3.5 mm input.

1. Check the Source Configuration

• Ensure that audio is being sent through the correct output from the source (e.g., HDMI, DisplayPort, or USB-C, not VGA).
• In the operating system, verify that the Beetronics monitor is selected as the output device.
• Check the volume level and mute settings on both the source and the display.

2. Digital Connections (HDMI, DisplayPort, USB-C)

• These connections support both video and audio. Check that the cable and port support audio transmission.
• Verify in the source settings (Windows, macOS, media player) that audio is being sent through the correct output device.
• Test with an alternative cable or source to determine if the issue is connection-related.

3. Analog Connections (VGA, RCA, BNC in Combination With 3.5 mm)

• VGA, RCA, and BNC outputs only provide video. For audio, use the 3.5 mm input on the display.
• Ensure that the 3.5 mm cable is connected securely.
• Use a short, shielded audio cable whenever possible to reduce noise.

4. Audio Output (3.5 mm Line-Out)

• Many models have a 3.5 mm audio output to route sound to external speakers, headphones, or amplifiers.
• This output is only active when using a digital connection such as HDMI, DisplayPort, or USB-C.

5. Test Alternative Scenarios

• Connect another source to rule out source-related audio issues.
• Test with a different cable or port to verify for cable or connector faults.
• Check whether the integrated speakers output sound when using a direct digital connection (HDMI, DisplayPort, or USB-C).

Beetronics displays can be operated in several ways. By default, all models are set to automatically power on when connected to power or when a valid video signal is detected. These settings can be adjusted as needed through the on-screen display (OSD) menu.

Control Buttons on the Display

• Basic functions such as power on/off, menu, input selection and OSD navigation can be operated directly via the buttons on the back of the display.
• Through the OSD menu, you can adjust brightness, color, contrast, timers, and automatic power on/off settings to your preference.

Included Remote Control

• Each display comes with an IR remote control.
• This allows you to intuitively operate the display’s OSD menu, switch directly between different input channels, and adjust the brightness on the fly (similar to volume buttons).

Optional External Dimmers

Most displays include a connection for an external dimmer, which is offered as an optional accessory. Two versions are available:

DMK7 (Single Channel)

• Function: Controls the brightness of one display via a rotary knob and turns the display on/off by pressing the knob.
• Connection: Connect the dimmer to the 3.5 mm dimmer port on the display.
• Configuration: Set the brightness to be controlled via the dimmer in the OSD menu (by default, control is set to the remote control).

DMK8 (Multichannel)

• Function: Controls the brightness of up to five displays simultaneously using a single rotary knob.
• Connection: Connect the dimmer to the 3.5 mm dimmer port on each display.
• Configuration: Set the brightness to be controlled via the dimmer in the OSD menu (by default, control is set to the remote control).
• Limits: The DMK8 does not feature an on/off function. In mixed setups, where different monitor models are connected, dimming performance may vary by model.

All Beetronics displays feature an adjustable backlight that allows for seamless brightness adjustment from 0% to 100%. The maximum and minimum brightness (in nits) varies by model. At 0%, brightness typically measures between 1 and 3 nits (not completely black). Exact values are listed in each model’s datasheet.

Brightness can be adjusted in three ways: via the physical control buttons, the included remote control, or the optional external dimmers.

The backlight is controlled internally via dedicated electronics. It is not possible to adjust the brightness externally via software (host operating system) or solely via voltage variation. Without custom firmware, software dimming is not supported. Therefore, for reliable control, only the physical buttons, the included remote control, or the DMK7/DMK8 dimmer are suitable.

Operation via the Physical Buttons

• Use the buttons on the back of the display to open the OSD menu.
• Select Backlight Brightness to adjust brightness directly.
• Changes are applied immediately and are retained after the display is turned off.

Operation via the Supplied Remote Control

• Each display comes standard with an IR remote control.
• The remote control has dedicated buttons for adjusting the brightness (similar to the volume control). This allows you to adjust the brightness step by step directly, without opening the OSD menu.
• Additionally, the remote control can be used to navigate the OSD menu and manage brightness or other settings from there.
• Control via Optional External Dimmers
• Most displays are equipped with a 3.5mm dimmer port for external dimmers. These are available as optional accessories and do not come standard with the displays. There are two versions:

DMK7 (Single Channel)

• Function: Controls the brightness of one display via a rotary knob and turns the display on/off by pressing the knob.
• Connection: Connect the dimmer to the 3.5 mm dimmer port on the display.
• Configuration: Set the brightness to be controlled via the dimmer in the OSD menu (by default, control is set to the remote control).

DMK8 (Multichannel)

• Function: Controls the brightness of up to five displays simultaneously using a single rotary knob.
• Connection: Connect the dimmer to the 3.5 mm dimmer port on each display.
• Configuration: Set the brightness to be controlled via the dimmer in the OSD menu (by default, control is set to the remote control).
• Limits: The DMK8 does not feature an on/off function. In mixed setups, where different monitor models are connected, dimming performance may vary by model.

To minimize the risk of damage during cleaning and ensure the longevity of the panel, follow these steps:

1. Turn Off the Display and Disconnect Power

• Turn off the display, unplug the power cord, and let the panel cool down.
• Never clean the screen while it’s powered on.

2. Remove Connected Equipment

• Disconnect all cables and peripherals to prevent moisture exposure or short circuits.

3. Do Not Use Liquid Directly on the Panel

• Never spray liquid directly onto the screen or housing.
• Excess moisture can leak inside the casing and damage internal components.

4. Use a Suitable Cloth

• Clean with a dry, lint-free microfiber cloth.
• For stubborn stains, lightly moisten the cloth with demineralized water. The cloth should be damp, never wet.
• Wipe in straight lines with light pressure.

5. Only Use Approved Cleaning Agents

• If water is insufficient, use a specialized LCD or glass cleaner.
• Avoid benzene, solvents, ammonia, abrasives, alcohol and acetone.

6. Avoid Excessive Pressure

• Never apply strong pressure, as this may damage pixels or the backlight.
• Do not use brushes or paper towels to avoid scratches.
• All Beetronics touchscreens are equipped with an IK08-rated glass front, providing excellent resistance to everyday pressure on the surface. The glass layer fully protects the underlying LCD. However, sharp or abrasive materials can cause scratches, so contact with metal objects or rough materials should be avoided.

7. Let the Screen Dry Completely

• Make sure there is no moisture or streaks visible before turning the display back on.

Beetronics displays are designed for long-term, reliable operation, even in integrated installations. Due to their low power consumption and wide input voltage range (9–36 V DC), they generate relatively little heat. However, proper heat dissipation is essential to maintain component longevity and prevent malfunctions.

1. Keep Ventilation Openings Clear

• Ensure ventilation openings are not blocked by surrounding panels or materials.
• For integrated applications, limited open space is often sufficient, but avoid completely closed spaces without air circulation.

2. Limit Heat Build-Up

• Avoid mounting in sealed cabinets or enclosures without airflow.
• For continuous operation in warm environments (above 40 °C), add ventilation or passive cooling if needed.

3. Avoid Direct Heat Sources and Sunlight

• Do not position the display directly next to heat sources or industrial machinery.
• Direct sunlight can raise surface temperatures beyond rated limits, even in cool environments.

4. Check Operating Temperature in the Datasheet

• Refer to the datasheet for permitted operating temperatures.
• Please note that prolonged use outside these values ​​may shorten the lifespan.

5. Inspection and Maintenance

• Periodically check that ventilation openings are free from dust or debris.
• Carefully remove build-up with compressed air or a soft cloth, without liquids or aggressive agents.

Proper configuration and usage significantly extend the display’s lifespan. Although Beetronics displays are designed for continuous use, there are factors that can affect reliability and lifespan. The guidelines below will help prevent failures and optimize overall service life.

1. Use Within Specified Environmental Conditions

• Maintain the operating values ​​for temperature, humidity and ventilation as stated in the datasheet.
• Avoid prolonged exposure to direct sunlight or heat sources. Even with models with wider temperature ranges and UV filters, the internal temperature may exceed the specified limit, negatively impacting their lifespan.
• When possible, provide shade, active cooling, or additional ventilation if the display is installed in an environment with high heat exposure or limited airflow.
• Keep housing and connections free from dust buildup as this can lead to overheating or malfunction.

2. Backlight and Brightness Management

• Set the brightness only as high as necessary for operational reasons. Backlight modules wear out faster at 100% brightness.
• Use automatic or external dimming solutions (e.g., optional dimmer) to adapt to ambient light.
• In applications where the display is operating 24/7, keeping the brightness at 70–80%  can significantly extend the lifespan of the backlight.

3. Limit Burn-In and Image Retention

• While LCDs are less sensitive than OLED or plasma panels, static content can cause slight image retention when displayed for extended periods.
• Avoid static logos, grids, or UI elements by periodically refreshing screen content.
• Enable a screensaver or periodic content refresh where possible.

4. Power Supply and Voltage Control

• Use the power supply included with the monitor or a Beetronics-certified power supply.
• Avoid voltage spikes by using surge protection or UPS in critical installations.
• Power off the display completely during extended inactivity.

5. Regular Maintenance and Inspection

• Clean connections and ventilation openings periodically to prevent dust and dirt build-up.
• Check cables and connectors for wear and tear and replace immediately if damaged.
• Schedule preventive maintenance inspections in continuous-use or industrial environments.

6. Consider the Total Lifecycle

• Each LCD panel and backlight has a specified MTBF and typical lifespan (see datasheet).
• By following the above guidelines, the operational life can often be extended substantially.
• When planning your projects, consider display replacement in line with the lifecycle of the entire system.
