Zhang Yuming Posted July 28, 2022 Share Posted July 28, 2022 Hello everyone, I have a screen of 1280x800 resolution. while connecting the screen to my rockpi-4b, the resolution is set to 1024x768, and there is no 1280x800 option in the display setting panel. after learning from Internet for days, I think the root is that my screen doesn't have a correct EDID information. so I made some changes to let the kernel ignores the screen's edid information and use specified edid file. The resolution is successfully set to 1280x800, the only problem is that the screen display is shaking, as the attached video shows. The edid file's timing settings are shown as below: I tried to change the settings but it doesn't work. It would be greatly appreciated if somebody can share with me the correct edid file of 1280x800 resolution. Thanks, Yuming normal video.mp4 0 Quote Link to comment Share on other sites More sharing options...
