Hi,
I have three monitors: 2 HD connected via dvi and 1 4k monitor (BenQ EW3270U ) plugged in via hdmi. This setup worked fine until I switched my motherboard and cpu today (I went from a gigabyte z97 gaming 5 with an i5 4690 k to a msi z490 pro a with an i9 10850k). Now whenever I start my computer up and the hdmi cable is plugged in, I do not get any display. I only get display (on my two HD screens) if I start the computer up with the hdmi cable from the BenQ unplugged. Once I start up, I can then plug in the hdmi cable to make use of my third screen. If I plug one of my HD screens in using the hdmi from my BenQ, there is no issue. I have tried lowering the resolution on the 4k. I have tried turning the power off on my 4k monitor when starting, but it I only get display if I remove the hdmi cable. I have also tried updating my graphics drivers and my bios... nothing has helped.
Does anyone have any idea how to fix this?
Thank you very much
