WOW, the plot thickens. Thought we had it nailed down. Good thing you didn’t send back the monitor. My GPU is normally mounted.
So, your issue here has me thinking about an issue I have with my fourth monitor which is NOT a PG42UQ. I have an Acer 27 in mounted above the triple screen in the pic. That Acer monitor will go black once in a while. The only way to get it back on is to change the REFRESH RATE. The value of the refresh rate doesn’t matter, but it definitely goes black when I stand up or make unusual movements in my chair.
What I finally figured out was there is some electric static going on around my pc and chair, desk area, etc. If I stand up and throw my blanket into my chair, the screen turns off. Or if I pet my dog rigorously the monitor turns off. I know without any doubt there is some electrical interference causing the monitor to go black.
So how does this relate to the PG42UQ? Well, I didn’t have this problem before. However, I did have to use a HDMI-male to DisplayPort-female adapter on the Acer 27 to connect the monitor to the HDMI port on my graphics card.
Since the monitor only goes black while playing games, I am thinking this issue doesn’t apply to you. I thought it is worth mentioning since we both have three PG42UQs monitors. It might be reasonable to think the monitors radiate electrical charge that could penetrate the protective wiring and create signal issues. I will post something on REDDIT in an appropriate subreddit and see if anyone has any insight or way to test this. I will report back after!
P.S.- Let me know if anything changes on your end. I am under the impression lowering the refresh rate to 100hz is a temporary “fix” for the problem and, the monitor is no longer going black/dark on you.
