Because intel Graphic driver is not ready for EHL Lake platform if you want to change your resolution and change your display mode you need to edit /boot/grub/grub.cfg change this line $GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" add command to this line $GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.force_probe=4555" Safe the grub and update grub $sudo update-grub $reboot then you can control display mode and resolution in OS but can not use OS display setting toolbar and if you use triple display remove one that still get triple dispay can not control to mirror mode <Note> Synnex Suggest Q4 test again <Later test>Tracy test Can display three outputs, but occasionally drops frames when playing 4K movies When playing a video, if there are other actions that eat up CPU resources, there will be more obvious frame drops Can be mirrored, Can be extended, Can be displayed independently Resolution can be modified but cannot be modified alone Need to modify the resolution of three screens at the same time to change the resolution |
