How to display the image from the video card at the same time with displayport and hdmi?

Question

AMD

I bought a RX5700XT video card and ran into such a problem - I use 2 screens, one via hdmi and the other via displayport cables, when both screens are connected to the video card, the image is displayed only on DP and the second screen is not detected in windows. If DP is disabled, then the BIOS image will be displayed on the HDMI monitor, and before windows starts loading, the screen switches to signal search mode (Windows is loaded at the same time). I know that there is a priority in the output ports of the video card, but I don’t know how to change it. Who knows how you can display an image from two video ports at once.
PS Before that, the RX580 was installed and there were no such problems.

Answer 1

If DP is disabled, then the BIOS image will be displayed on the HDMI monitor, and before windows starts loading, the screen switches to signal search mode (Windows is loaded at the same time).

That is, this monitor on this HDMI cable is not friendly with this HDMI output?
It was similar: I replaced the vidyuhi - some of the monitors on the DP began to fail. Replacing the wires fixed the problem.
Change the wire, look for a DP-HDMI adapter, swap monitors, ...
