I have  a U2723Qe, an HP Elitedesk PC with a Radeon R7 430 graphics card with 2 DP out, and a Dell Inspiron 3020 Desktop with a NVIDIA® GeForce RTX 3060.

Only one displayport seems to be working.

The HDMI works, one DP works, but when I change the cable to the other DP it does not work.

I cannot set up the 2 PC view, as the monitor does not see the second PC.

Either PC can work on the one DP.

I have run the diagnostics as the documentation says.

As I only received the monitor yesterday, I am wondering if I am doing something wrong or do I need to return it?

Thank you
