I finally got some good pics to show what im talking about here.

Pics:

Important things to consider:

  • -This ONLY happens when watching full screen videos, regardless of the player (youtube, windows media, VLC), and it happens anywhere from 20 seconds - 10 minutes into the video).

    -Graphic intensive games do not cause errors, everything looks great no matter how long I play.

    -It seems to only happen when watching anime or videos recorded through personal cameras.. it doesn't happen when watching actual movies (unless they are anime).

    -This never happens when my laptop is connected to the TV with the same HDMI cord.

    -Its not the GPU, my old GPU did this, i RMA'd it, new GPU does it too.

    -After this happens, cycling inputs on the TV will revert it back to normal.

    -After this happens, changing resolution via NVIDIA control panel will revert it back to normal.

    -If i take a screenshot of the screen while the colors are messed up, it looks like a normal screenshot (so the error is clearly with the TV).
Hardware details:

More notes from my reply below

  • -Old GPU was also a GTX 970 (gigabyte tho)
    -Same issue with different HDMI cords
    -Same issue with different ports on the TV
    -Onboard graphics doesn't cause the issue
    -I don't have different OS to try it on (although laptop is win 7 and this PC is 10)
    -I don't have a different TV to try it on also

I would appreciate any help with this. I really have no idea what is causing this. It doesn't make sense to me that this PC causes this error, but my laptop doesnt. All drivers are updated and all that.

Was the old GPU a NVidia as well? Have you tried removing the GPU and using the onboard graphics? Have you used a different HDMI cable? Have you tried a different port on the TV? Have you tried the PC on a different TV? Have you tried a different OS like a live Linux distribution?

So it seems the issue is something to do with Nvidia and the TV.. which I thought.. but i don't know how to go further from there.

Please go into nVidia driver settings panel. Then on left hand list, select display->change resolution. On that page go down to "output dynamic range" and set it to limited. If that doesn't work, you can also try altering output color format, which is on that same page at the bottom..

Already tried using both Full and Limited. Same issue persists.

Also tried all 3 options under output color format. The second option causes artifacts on my screen. With the 3rd option the issue still persists.

Sorry for the stupid question here, but did you hit apply after changing driver settings and cycled TV power?

Ahh i have seen this before try changing the resolution to 1080i.
wait have you tried a certified high speed hdmi cable using multiple low speed cables will have no effect.
Have same tv had same problem high speed cable fixed it for me.

1080i causes blurry lines and makes the text kinda hard to read on my TV. Isn't 1080i worse quality than p?

If it works that'd be great, but i dont know if i would take the overall quality hit just to prevent this error. Do u know why that would cause it? Maybe theres something i can do other than that?

But that's awesome you have seen this before.. literally everyone i've asked has not seen this before.

I'll have to try a high speed cable... i don't have one on hand so i will have to order one. Does that make sense that the 970 would require a different cable than the onboard graphics?

I don't know how to do all that unfortunately. And if i did do that, and there is no error, what would that show me?

That it's a Windows/Driver issue. Have you totally remove NVidia drivers using a removal tool and then tried installing an older version possibly?

Seems it's an issue with that TV model and what it expects and what the GPU actually puts out.

You could also go into the advanced properties and try and make sure the refresh rate is 60, or try 30.

Refresh rate was set to 60 causing errors. I read some guide that said changing it to 59 might fix it, so i tried that and it still causes errors. The error is also at 30 refresh (and 30 looks ugly).

I've tried uninstalling/reinstalling the driver (using that removal tool), and have also tried about 5 diff versions of nvidia drivers, all causing the same error.

I'd give ubuntu a shot then. Either it's a very weird, rare, incompatibility hardware wise between the TV and GPU regardless of anything, and Ubuntu would help determine that possibly, or it's a rare imcompatibility between the gpu, tv and windows drivers and some possible default setting, that wouldn't present itself when in linux.

Have you tried other resoutions, like 720p or 800x600 or something and how does it work, can't remember if that's been tried and it's results or not at this point. lol.

I have not tried using lower resolutions, but I will give it a shot and report back. Testing this is a bit of a pain because like I said sometimes it can take 10+ minutes to see if it actually glitches out or not.

The other poster said he had the same TV and said using a high-speed HDMI cable fixed it for him. Does that make sense that a high speed cable would be required for the 970 and not for the onboard graphics? Given, i have no idea what cables im using right now (they might be high speed already, i dont know).

Again, thanks for all your help with the troubleshooting.

Hmm that is interesting, i did not know that about it being 2.0 and those being rare.

I'm gonna try lower resolutions, and if that doesn't work i'll order a high speed cable. I'll report back once i tested all this stuff (might be a few days), again thanks so much for helping!! Mucho appreciated

If this happens only with video that is streamed from the internet then I would suspect the problem may be caused by one of the Windows power saving settings. I've encountered times when a "browser" fullscreen video does not disable the screensaver as it should. There is also a "powermizer" setting in the NvIdia control panel that might not work properly with your card... just a guess. I change that setting to maximum performance for my low-end gpu. But on my other PC with a more powerful gpu, the setting doesn't seem to have any impact on performance.

Happens with both streaming videos and local files. It's important to note that it happens ONLY in full screen. If i have a video maximized to the full boundaries of the TV but its not in "full screen" it won't glitch out.

Edit: where is that powermizer option? I don't see it

Tried everything in this thread.. still no fix.

I'm getting a new TV in 2 days so will see if that fixes the issue. Maybe it is a weird incompatibility between the TV and nvidia.
