* What operating system is installed on the samsung 930xcj? * List all of the samsung 930xcj video out ports * Explain how the samsung 930xcj is currently connected to the U4025QW using which cable and ports * Are there mulitple computers connected at the same time to the U4025QW?
I have a similar issue. When attached to two different systems via HDMI cable (Nvidia 3070 Ti and 5070), the screen will blank out for a second or so at random times. Both cards support HDMI 2.1 and I am using the Dell-supplied HDMI 2.1 cable. Changing refresh rate doesn't help. No similar issues observed for DP or USB4. I contacted Dell support who wanted me to reinstall Windows even though I was having the same problem on two different machines (one is Windows 11 23H2 and the other is 24H2. When I suggested this was not helpful, the service rep terminated the chat. Wow.
I was able to do a fresh install of Windows 11 24H2 on a different system with all updates. As expected, the problem remains. Dell is shipping me a replacement.
