Windows 10 21H1 Laptop: HP Elite Dragonfly G2 Display: HP Z27k G3 (3840 x 2160p) Docking station: HP USB-C Dock G5
All firmware, BIOS etc. uptodate and tried everything possible.
Following problem: According to these specs, it should be possible to operate at least 1x 4k display @ 60Hz without any problems with DP 1.4 even without High Res mode DP Alt Mode (not an alternative for us). (According to specs even 2 displays should run at 4k@60Hz)
