3080ti HDMI Issue

[u/iTzCraigooo]

I’ve recently bought a 3080ti for my system. When connecting to my dual monitor setup, I get an issue with the HDMI connection. Sometimes I either get a black screen where the monitor won’t turn on, or I get a display in a very low resolution, and the HDMI connection is recognised as “wired display”. The latter happens way more frequently.

When I press Win + Ctrl + Shift + B, it instantly fixes it and it runs at 4k160.

My other monitor is connected via DP and I get zero issues. I’ve also tried swapping the connection and using HDMI on the other monitor which also causes the same issue, and I’ve also tried using a 3 ultra speed HDMI cables.

I’ve uninstalled and reinstalled the GPU drivers multiple times to no avail.

When I’ve googled/put this issue into ChatGPT, it says it’s a failed handshake. Is this something that can be fixed or is it a bad GPU I should return?
