U2515H, PC crashes after switching to another computer.
I encountered a weird problem with my monitor. I am not sure what's wrong with this. I have a desktop connected to my U2515H and it works correctly for several months. A week ago I bought an Intel NUC and connect it to my monitor as below:
Desktop (Windows) DP out port --> DP to mDP cable --> U2515H mDP in port
Intel NUC (Ubuntu) HDMI out port --> HDMI to HDMI cable --> U2515H HDMI in port
There's a problem that once I switch to the Intel NUC from the desktop, I always get a blank screen after I switch it back to the desktop. After a moment, the desktop would restart automatically and it seems my desktop had crashed. Can anyone figure out the root cause?

DP1.2 should only be Enabled if you are daisy chaining a second U2515H monitor to the first one via the DP out port.

Does the desktop PC have an HDMI out port to test on the U2515H HDMI in port that the NUC is currently attached?
Does the NUC have a DP or mDP to test on the U2515H DP or mDP in ports?

Hi,
THere's no DP on the NUC.
Fortunately, after I disable the DP1.2 (I am using GT1030), the issue is not happened for now.
I'll try more times to ensure if this is the root cause.
Thanks.

HI,
I checked the Spec. of nvidia 1030, it should be DisplayPort 1.2 Certified, DisplayPort 1.3/1.4 Ready.
Why I am not able to enable the DP 1.2 option?
Is there any limitation?
Thanks.
