This may be caused by many factors, but in general can be described as unstable brightness, and happens. When you can see light gradations changing too harshly, instead of in a subtle and smooth manner, flicker becomes noticeable. The monitor changes brightness levels in a sudden and fast way that can be very irritating and adds eye strain. But if the flicker gets too bad, there are some things you can do.
- Reset your monitor. Open the monitor’s OSD menu, go to System > Reset all > Yes.
- Except for the power cord and video cable, remove all devices connected to the monitor.
- Ensure your power cord is plugged directly into the wall socket to avoid an unstable power supply that may be caused by a third-party power supply, UPS, or other adapters.
- Ensure your input device only connects to this monitor and removes unnecessary connected devices to the input device.
- Ensure all video and power cables are properly connected on both ends.
- Download the Resolution File from the BenQ website and set your monitor to its native or supported resolution and refresh rate.
- Close all software programs, especially drawing software or browsers, to avoid color shift problems caused by software switching ICC profiles in the operating system.
- Try a different video cable and video port for the monitor and the input device.
- Try the other different types of video cable and video port of the monitor and the input device.
- Test the display with another device. If the flicker occurs when using your PC, try the monitor with a console, a different PC, a Blu-ray player, and so on.
- If your input device is an M series Mac device, please refer to the article for more information or contact BenQ Support for a solution.
If the flickering persists, the monitor may have defective hardware. Please get in touch with BenQ Support for further assistance.
