Computer Hangs for minutes when connecting TV.

[Crazedbiker]

Hi everyone, I am at a bit of a loss. I have a pretty badass PC, RTX 4090, 7800X3D, 32gb of ram, gen4 SSDs. It generally treats me well but when I connect my Samsung 4k tv to it, the whole computer hangs and is totally unresponsive for between 1-3 minutes. I am using HDMI 2.0 for the TV as all of my DisplayPorts are taken up by three monitors.

Making other changes like switching the TV to game mode (120 hz) from regular mode also cause this hanging to happen.

It does not happen when unplugging the tv. It does eventually work, but its very strange that it happens every time. This kind of thing has never happened to me with my laptops or older desktops. Any help would be appreciated. Let me know if I have forgotten any details. I have no screenshots to post as the issue is just a freeze. Thanks!
