I'm guessing you're hitting some dual mode adapter limit. Please file a bug over at [1], add drm.debug=14 module parameter, and attach dmesg from boot to hitting the issue. BR, Jani.

Intel UHD resolutions
Hi, I would like to use QHD resolution (2560x1440) with my shiny new computer and display. That resolution works if I boot Windows 10 (cough). What do I need to do to use that resolution in Linux? I first tried openSUSE 15.3 (kernel 5.3.18-59.19-default) then I build a v5.14 kernel and tried that. Both of them max out at FHD (1920x1080). I am booting with "i915.force_probe=4c8a" on the kernel command line. My desktop is XFCE4. CPU is: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 167 model name : 11th Gen Intel(R) Core(TM) i9-11900 @ 2.50GHz stepping: 1 microcode : 0x40 cpu MHz : 1021.742 cache size : 16384 KB physical id : 0 siblings: 16 with an H470 chipset.
