APantaloni said:Hello,
I have the same issue with an Asus XV280K when using displayport and a Zotac 3070. It was not doing that with an older geforce 970 (also on displayport). Tried 2 different displayport cables, no difference. Have you been able to solve it with a different cable?0 -
It's not just 3070. I have exactly same issue, with two computers, one happens to also have 3070, but same issue is also present with gtx 1080. Since displayport is somewhat broken in this monitor it makes no sense for nvidia gpus (since it won't support adaptive refresh rate over hdmi).
Also have to return it.

Apparently, you are not the only one, I also have the same problem but with Acer Nitro XV240Y P (DP 1.2) and Zotac 3060 ti (DP 1.4a). Got a different cable (DP 1.4) and that still doesn't work. However, previously using GTX 1060 6GB did not encounter this problem until upgrading to 3060 ti. I believed it has something to do with the DP 1.4 on the GPU itself, as it disconnects and reconnects when windows put the monitor into sleep (You can hear the windows device remove sound).
The only way I now is to test it on a different monitor to see if it's still the same issue, if not just manually turn off your monitor when not in use until the GPU supply is back to normal. I've not tried messing with the GPU drivers yet.
You can also try updating your GPU/Mobo bios to see if that helps.. For my Zotac card, I've tried updating but its still the same issue.
I guess for me RMA GPU is the only choice.0 -

Hi everyone.
I just wanted to chime in... I think I have resolved the issue !!
First off, I had the exact same problem. I tried almost everything - different DP-cables, BIOS-settings, BIOS-update, Windows-settings etc. I even turned off the PSU from my PC and the 2nd monitor would still turn on the backlight every 30s or so.
I too have an Acer monitor (Acer Nitro VG240YPbiip to be exact) and until I switched to DisplayPort I had no issue with it.
The monitor has a setting called "AMD Free Sync Premium".
Since I turned that off on the problematic 2nd monitor, it stays off when it's supposed to.
Just thought I would share this information since it resolved my issues

Never mind, it did it again last night0 -

xenon2000 said:Zotac will RMA my card. But they said it will take 2-3 weeks or longer and they won't start the process until I ship them my card first. So I would be without a computer since my Ryzen 5950X doesn't have integrated video. But after all the things I have seen with this monitor, I am not convinced it's an issue with the 3070 but likely how this monitor handles DP 1.4 GPU ports. So I am looking for a different monitor.0

For you two and anyone else still having this problem, the issue is with the DisplayPort cable. There is no other cause. DisplayPort cables have a power pin that is not supposed to be connected, read more here. Many displayport cable manufacturers ignore this and connect it anyways which causes problems such as this one. It can also fry your GPU. Find a cable on Amazon and check the reviews to make sure it does not have pin 20. BENFEI cables do not have this issue. You could also try to cut pin 20 ( look online for instructions on how to do so) but your mileage may vary doing this, and you might cause the cable to short.0 -

got the same issue with a VG242Y, RTX 3070 and displayport that comes with the screen. I have yet to try the different display port cable trick.

2x VG280K here. Same issue. I've tested my DP cables for pin 20 — it's not connected on any of them. Video card is a PowerColor RX580.
