GTX 750ti 2GB problems

[mickrick]

I recently bought a Gigabyte GTX 750ti 2GB for use in my home entertainment pc, and so I could stream games to my Nvidia Shield console. I have one hdmi connection going to my tv for hd and 4K 60hz video, while the second goes to my Onkyo AVR for Dolby Digital HD and DTS HD audio. Video output is set to mirror screen 1 to screen 2

I have had nothing but issues since day 1. When I try to run a game on the pc, the screen goes pink and green, the upper half of the screen is split, like a 3D image, and the bottom looks like its corrupted. I also use Kodi for video and audio playback from bluray, dvd or network storage (no internet streaming) and the picture has tearing. Trying to change the resolution causes kodi to crash and the screen goes pink.

My pc is built around pretty high spec components - Asus ROG Maximus VIII Gene motherboard, 24GB (2 x 8GB matched, 2 x 4GB matched) DDR4 ram, 256GB Samsung system SSD M.22 and 480GB Sandisk II Ultra SSD, Win 10 x64 Professional.

So, any ideas what might be happening here?

I have always noticed page tearing on mirrored mode(try to swap what screen is primary.). I noticed this first when trying to side by side compare monitors. It may have to do with slightly different timings between the screens. I have never noticed this in any other mode.

Bluray it self is kind of picky and may object to the mirror mode as well(copy protection is not user friendly).

Does your Onkyo have any other inputs you can try. OR better yet can it pass the HDMI signal so you are only using one HDMI port.

Another option would be to try your luck with audio return. This should send any audio from the TV back on HDMI to the receiver(but it may not may not support uncompressed audio). You will need to see the manual on your TV and receiver to get this set up.

4K adds allot to this since many commercial products that extract audio or split HDMI may not yet support 4k

Yeah everything is up to date. I'm pretty diligent about things like that. I'm just dreading having to do a clean reinstall of windows only to find out that it makes no difference.
