Hello,
I have since the beginning of the year a xfx speedster merc 319 amd radeon rx 6900 xt black installed in my Rehner and as a 2nd monitor a Crossover 27Q LED over active (with USB power supply and Analogix ANX9830 chip) Delock adapter from DVI Dual to Displayport connected.
Since the latest update I have again the same problem as in the beginning, when I only used an adapter cable from DVI to Displayport, namely:
1. resolution is fixed at 640x480, both in Windows and in the Radeon software.
2. i can't set the resolution manually via the software under custom resolution -- >.
2.1 QHD which the monitor can actually do always gets the error message "The Custom Resolution is not compatible with the display".
2.2Full HD I can set and also confirm, but then have a black monitor.
Can someone please help me here, I'm really desperate!
