Monitor loses signal within 5 minutes of turning on the computer (self.techsupport)

I have an Benq EX2510 (the older model from 2020) and I have a gtx 1660 super with an i5 10400f in my pc. The motherboard is MSI b460 m pro vdh wifi.

This the first time I'm experiencing an issue like this. The monitor loses signal and doesn't even turn back on even on plugging the hdmi cable again. This has been Happening on every single boot for the last 2 weeks.

The monitor literally loses signal even when it's at the bios logo screen or boot menu sometimes.

After it loses signal, the monitor will stay in that state for the next 30 minutes even if I power off the entire system and turn it back on. The monitor does recognizes different input connections although none of them gives any output.

I tried connecting a laptop to the monitor and it seemed to work fine. This leads to me think that something is up with my GPU.

So far I have tried -

  • Different cables - 1 HDMI cable as well as 2 different DP cables but same result.
  • Turning the monitor on after the computer has started.
  • Powering off the monitor and turning it on again.
  • Taking the GPU out of the PCI slot and placing it back in properly.
  • Checked the PCI power connecter for any lose contacts. Also tried with a different PCI power connector.

What do you suggest I do next ?

You need to try a different display if you can. You've already ruled out the cable, so try the computer with your TV if you can, and see if it works. If it does work, try the cables that you've already tested too. If they work with the computer and the TV, then you know that the monitor is faulty and can go from there.
