I have an eVGA 3060ti FTW3 Gaming that I purchased from bstock. Upon boot when hooked up to a 4k display it immediately shows a very heavily Artifacted image and freezes right after the POST splash screen. I initially thought this was a defective gpu and evga was quick to replace it. However, the replacement is doing the exact same thing so I decided to do some trouble shooting to see what the issue might be.

I have found this image and freezing happens when the gpu is in two different systems, a b460i with an i5 10500 and Silverstone 550w Platinum (the intended system) and a b450m with a athlon 3000g with an evga 850p5 (slapped together for testing purposes)

This is only happening with a 4k tv display. I don’t have another 4k display to test, but all of the gpus work fine hooked to 1080p and 1440p monitors. The tv works fine at 4k 120hz with the ps5 via hdmi.

To make things worst I took the 3090 out of my main gaming pc and put it both test systems and this artifacting and freezing happens as well. That GPU runs fine on my main pc with 2x144hz 1440p monitors hooked up by display port.

Finally, I have found there is no freezing nor artifacting when hooking to the tv using the onboard graphics of both systems or a 1650 super. The onboard graphics on the 3000g did have very noticeable input lag but that might be unrelated.

I have tried a few steps with the tv as well. I used multiple different hdmi ports including the 120hz port and the 60hz port, with no difference. I used a few different HDMI cables including the one that came with my ps5 and has been able to push 4k at 120hz. I went through my signal setting on the tv trying standard, enhanced and VRR on the ports that allowed it. The only difference was the Artifacted image changed a little. Unfortunately there are no display ports on the TV.

I have also tried various bios setting that went along with the “black screen” issues in the forums. I forced pci gen 3 rather than auto, and I shut off fast boot. I tried disabling onboard video. I made sure fresh drivers were installed while I was hooked to a 1080p monitor.

At this point I am at a loss as to what to do next. The 3060ti, as mentioned before, works fine on a 1440p monitor under gaming and folding loads. The only two conclusions I have came to are:
The TV will not accept a 4k signal at a high refresh rate and is causing some sort of corruption rather than just clocking it down.

Or mining has destroyed the memory on the 3060ti (both of them from b stock) and 4k is the only thing that accesses enough of the memory. The 3090 had been mined on previously as well. This seems like the less likely option being that it happens on boot and that 3090 has ran a 1440p display in cyberpunk with no issues. That uses way more vram than windows booting in 4k I assume.

I am at work and can attach an image of the artifacting image when I get home. Sorry for the long story, but I wanted to list everything I have tried so far. I am happy to try any troubleshooting one may come up with as I’m starting to loose sleep over thinking about what to do next.

Edit: Wanted to point out I am totally fine with 4k at 60hz, I don’t really expect the 3060ti to push much beyond that anyways.
