Graphics Cards

Journeyman III

Display is black with RX 6750 and Asus VG 279

Hi everyone, I've already talked to the support of Gigabyte (graphics card manufacturer) as well as the support of Asrock. Furthermore, the graphics card has already been sent to the manufacturer and returned as tested. The bios is up to date and also reset. WIN 11 with all updates. I have the following problem: 

When I switch from my GTX 970 to the Gigabyte RX6750, the system gets stuck in the ASrock boot menu. At this time, the Asus VG279 is connected and a DELL P2414H. If I then only connect the DELL, the system boots up and the monitor has a picture.

If I now connect the Asus I also get a picture and even after a restart I have a picture on both monitors. The next morning I start the system and I don't have a picture on either monitor. Then I connected the PC to my 11 year old Asus VG236 monitor and have a picture again. The monitors are connected via DP and these have already been replaced.

Many greetings
