downunder52 Posted October 7, 2023 Share Posted October 7, 2023 I had the same problem and solved it by using the other HDMI port on opi5+. Good luck 0 Quote Link to comment Share on other sites More sharing options...
thanh_tan Posted October 10, 2023 Author Share Posted October 10, 2023 I tried to use every HDMI port, but no sucess. Even use only 1 HDMI, still 1920x1080 0 Quote Link to comment Share on other sites More sharing options...
royk Posted October 10, 2023 Share Posted October 10, 2023 @thanh_tan Are you using X11 or Wayland? Orange Pi has the option "NoEDID" "true" for X11 which you could try https://github.com/orangepi-xunlong/orangepi-build/blob/next/external/packages/bsp/rk3588/etc/X11/xorg.conf.d/20-modesetting.conf 0 Quote Link to comment Share on other sites More sharing options...
InfernalWolf666 Posted October 24, 2023 Share Posted October 24, 2023 (edited) Greetings! I had the exact same problem. On all the non-official images on my 4k TV, there was a purple screen, then black! For a long time I could not understand what was wrong and how to solve this problem! It turned out to be simple, in the TV settings, you need to select improved quality on the HDMI source! And everything worked Edited October 24, 2023 by InfernalWolf666 0 Quote Link to comment Share on other sites More sharing options...
