Monitor is no longer recognized after AMD Software update


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!

This an English forum, so please speak English!
However, I might understand what You are saying.

You have a problem with resolution 640x480?
This is possible due the monitor firmware, which is causing this.

If Your monitor is a Gigabyte AORUS-FI27Q - then make sure it is loaded with Firmware F03
You will need a USb-cable to support the changes.

Or any other monitors, just upgrade its firmware.

Danke für Ihre Antwort, ich habe alle in englische Rede geändert.

Nein, ich habe einen Crossover-Monitor mit nur am DVI-D Ausgang.
