How to fix flickering and pixelated display with HDMI output?
When the display monitor is flickering or pixelated, it is recommended to clarify the time of the occurrence. First, troubleshooting with the hardware installation such as graphics card power connectors and the PCIe installation. Then switch video input interface and the cable on the monitor, run the testing under BIOS environment to identify the issue is with the operating system or it happens all the time. If the problem does not exist under BIOS environment, it is recommended to follow the software troubleshooting method.
● Hardware troubleshooting methods
o Graphics card power connectors
The 6pin or 8pin power connector should be properly inserted to the graphics card.
(If the graphics card has multiple separate connectors, please load all of them to make sure the power is fully supplied)
o Reinstall the graphics card
Remove the graphic card and assemble again to make sure the PCIe pins are well attached
o Switch video input interface on the monitor
Switch the video input to the other interface of the display card for testing. For example, switch the monitor input to DisplayPort and connect it to the DisplayPort output interface from the video card, see if there is display. If there is display on the DP interface, it means the graphic chip is fine, it is still providing the images. Please replace the HDMI cable for testing to confirm whether the cable is abnormal.
o Check the issue under BIOS
Upon powering on the PC, please start hitting the [Del] key continuously to enter the BIOS menu. See whether the screen is still flickering.
Note: If the problem is not exisiting under BIOS, the problem of the flickering screen should caused by the operaing system and the drivers. If the issue still occurs, please continue the troubleshooting method.
