This issue may be caused by electrical interference or incorrect signal settings.
To troubleshoot:
- Ensure the monitor cable is firmly connected.
- Move nearby electrical devices (speakers, power adapters, etc.) away from the monitor.
- Check that the correct refresh rate is selected in your display settings.
- Test with another cable or port if possible.
If the screen image is not centered or properly sized:
- Use the monitor’s Auto Adjust function in the on-screen display menu.
- Ensure the resolution is set to the monitor’s native resolution. Adjust horizontal and vertical position settings in the monitor menu if necessary.
If you notice dead or stuck pixels, these appear as very small dots that remain permanently black or show a constant color. A stuck pixel usually displays a single color (red, green, or blue), while a dead pixel remains black. You may try the following:
- Use pixel-fixing software or videos that rapidly cycle colors to attempt to reactivate stuck pixels.
- Avoid applying pressure to the screen, as this may cause additional damage.
- Check your monitor’s warranty terms, as replacement policies may apply if the number of defective pixels exceeds the allowable threshold.
If the issue persists, document the location and behavior of the pixel and contact customer support.
A fuzzy image or ghosting effect may be caused by incorrect resolution or signal interference. Please try the following:
- Set the display resolution to the monitor’s native resolution in your operating system settings.
- Check that the video cable is properly connected.
- Use high-quality cables where possible.
- Run the monitor’s Auto Adjust function (if available) from the on-screen display menu. If the issue continues, try another cable or graphics port.
If one of the primary colors is missing or the image appears tinted, this may indicate a cable connection issue. Try the following steps:
- Check that the video cable is fully inserted on both ends. Inspect the cable and connectors for bent or damaged pins.
- Try another cable if available.
- Reset the monitor’s color settings via the on-screen display menu.
If white colors appear tinted or inaccurate, it may be due to incorrect color settings. Please try the following:
- Reset the monitor’s color settings through the on-screen display menu.
- Check the color temperature or color mode settings.
- Ensure the graphics card color settings in your operating system are not overriding the monitor’s settings.
- Test with another cable or device to rule out signal issues.
If your monitor or connected device includes a rechargeable battery and it is not charging:
- Ensure the charging cable is properly connected.
- Verify the power source is functioning.
- Try a different cable or power adapter if available.
If the battery still does not charge, it may require service or replacement.

Accessories
If your device stops responding, confirm that the device or USB receiver is working properly. The steps below will help to identify if the issue is related to the USB receiver:
- Open Device Manager and make sure your product is listed.
- If the device or USB receiver is plugged into a USB hub or extender, try plugging it into a port directly on the computer
- Windows only — try a different USB port. If it makes a difference, try updating the motherboard USB chipset driver.
- Try using the device on a different computer.
- If it’s still not working on the second computer, check Device Manager to see if the device is recognized.
- If your product is still not recognized, the fault is most likely related to the USB receiver rather than the keyboard or mouse.
- Clean the button/key with compressed air.
- Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.
- Unpair/repair or disconnect/reconnect hardware.
- Upgrade firmware if available.
- Windows only — try a different USB port. If it makes a difference, try updating the motherboard USB chipset driver.
- Try on a different computer. Windows only — if it works on a different computer, then the issue might be related to a USB chipset driver.
- Replace with new batteries (wireless product with dry batteries]
- Pointing devices only: If you’re not sure if the problem is a hardware or software issue, try switching the buttons in the settings (left click becomes right click and right click becomes left click). If the problem moves to the new button it is a software setting or application issue and hardware troubleshooting cannot resolve it. If the problem stays with the same button it is a hardware issue.
- If a single-click always double-clicks, check the settings (Windows mouse settings) to verify if the button is set to Single Click is Double Click. NOTE: If buttons or keys respond incorrectly in a particular program, verify if the problem is specific to the software by testing in other programs.
Check whether you are using the mouse on any reflective, transparent or uneven surface, if yes, not to use the mouse on these operating environments.
- Try to replace with a new battery.
- Check the setting to verify if the DPI is set at a proper value.
- Check whether it is connection issue.
- Try on a different computer. If your cursor does not move or the buttons or keys don’t work:
- follow the synchronization method mentioned in the manual of the receiver you buy;
- contact with local service center to get the synchronization method.
If you have wired devices follow the next steps:
- Plug the device into a different USB port on your computer. If possible, don't use a USB hub or other similar device. If using a different USB port works, try updating the motherboard USB chipset driver.
- Windows only — Disable USB Selective Suspend:
• Click Start > Control Panel > Hardware and Sound > Power Options > Change Plan Settings > Change Advanced Power Settings > USB Settings > USB Selective Suspend Setting.
• Change both settings to Disabled. - Update firmware if available.
- Try testing the device on a different computer. If you have wireless devices follow the next steps:
- Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.
- Move the device closer to the USB receiver. If your receiver is in the back of your computer, it may help to relocate the receiver to a front port. In some cases, the receiver signal gets blocked by the computer case, causing a delay.
- Keep other electrical wireless devices away from the USB receiver to avoid interference.
- Unpair/repair or disconnect/reconnect hardware:
- Update the firmware for your device if available.
- Windows only — check if there are any Windows updates running in the background that may cause the delay.
- Mac only — check if there are any background updates that may cause the delay.
