Glitchy pixelated video playback. Only happens on video. Screen otherwise looks good on menus and Google TV home screens. Brand new Hisense 4k TV... Any help? Tried power cycling and factory reset...

Happens on apps, e.g. YouTube TV, YouTube, Prime Video, Netflix, Disney etc.

This is using the native Google TV built into the this 50" Hisense 4k TV.

Troubleshooting:

• Plex app played video well (interestingggg)

• Animated shows on Netflix are working but human actor content (lol) is experiencing the glitch (wow, this is odd).

• I even tested video within the browser on YouTube.com and it still experiences the problem! The video is glitchy but rest of browser Window content is good.

• I played a trailer off Google TV's movies section, and it actually played okay. But then when I tried to play the actual movie, glitchy pixelated screen.

• plugged in Nintendo switch to HDMI, that worked fine.
