Is my graphics card dying? Visual artifacting

[Boothy128]

Hey. Hope you can help. 

 

Powered up my pc today and noticed a vertical line going top to bottom on my screen. 

 

I can only describe it as a visual artifact. It flickers constantly. Only really noticeable on darker backgrounds. 

 

RTX 3090 connected to an LG C9 OLED via a HDMI 2.1 cable. I've updated the drivers in geforce experience. 

 

I've tried a different cable, and I've tried different hdmi port on the TV. 

 

The TV doesn't show the issue on anything other than the pc. 

 

There's only one hdmi port on the card so I tried a Display port to HDMI adapter and the issue has gone, but now it can only do 1080p 60hz. 

 

My guess is that the low res and refresh is a limitation of the adapter more than anything else, but it still allows HDR. 

 

What do you think? 

 

Broken hdmi port on the graphics card? 

 

Could I get a better display port to HDMI adapter to get 4k 120 VRR again?

check ur temps

Does not necessarily mean your GPU is failing. As aforementioned, checking temperatures of the VRAM in particular will give you a better idea of the root cause. Can it complete a FurMark test with no issues? (Make sure the temps are acceptable before doing this, of course.)

Does it show up in screenshots?
