Question Connecting TV causes my PC to crash ?

[FinalKenpachi]

Hello everyone, sry it's little bit complicated to explain i will try my best to explain short as possible.
I also record quick video you guys can maybe check it out to see the problem.
I have 3 monitors and 1 TV. You guys can see detail of my system below this message.
Whenever i connect my HDMI cable from my TV to the GPU my main monitor doesn't work anymore.
If HDR is Enabled on TV, turning on the TV makes PC crash, even if I try to restart, the PC won't turn on until i unplug the cable.

Sometimes it works. But whenever PC goes Sleep (monitors go off for a while) Than my multi monitor setup got broken again. Main monitor wasn't coming on until i unplug the HDMI cable from the TV.

Here is the weird part. If i unplug the HDMI Cable from TV to the motherboard, GPU has 0 problem. But some reason Games don't like it i cannot increase the resolution to 4k even TV Displays 4k.

Hopefully you guys understand ask me any additional question to figure out whats the problem please and Thank you all!

We had the same mini nightmare your describing.

Three years back never a glitch on my sons computer. I bought him a 65 inch 4k TV that he as well hooks up to his PC.

Than the calls, dad can you swing by my place and see what's up between PC and TV.

Here the short version it was Windows 10 and HDR + TV that was the issue.

He was so angry over the same issue your having but we dug down and now fixed.
Two things we did on the day Windows 11 released grab it and installed the new OS and two even though we had just bought him a high end HDMI 4k video cable it seems he needed a higher bandwidth cable.

Will this help you IDK but if your running Windows 10 that's where we were hitting the wall and 11 fixed it.

Thanks for the answer, im already using Windows 11. The part that i don't understand same Cable working without problem at Motherboard HDMI port. Also it's not only HDR problem. PC won't crash anymore without HDR enabled on windows setting for TV but still my multi monitor setting messing up every time i restart pc or re-open. Unless im unplugging HDMI cable from TV on my GPU.

Sorry if I am way off here, but I would suggest you compare the video capabilities of your monitor and your TV. I less familiar with computers as a source but I have see crashes before at work do to video settings. I would suggest you step down your resolutions, maybe even step down to 720P and work back up when everything works stable with no issues.

Turn off HDR from the computer fist to remove that factor and make sure everything else works correctly. up to your highest resolution of 4k. Then assuming your computer has different settings for HDR, test them one by one, I would guess your computer monitor accepts a higher grade HDR then your TV .
