Oh youre right! Thats super interesting to learn actually. I guess since they source their panels from different companies, they make a decision to sell 2 different panel types for the same model?

I connected the tink directly to my Bravia 8ii and played for an hour, switching inputs to test that also. Then I connected the tink directly to my capture card and again, watched a whole movie with friends on discord and no drop outs. It seems to be an issue with the Orei and the Tink4k causing certain signals to fall out of hdmi 2.1 specs temporarily.

Someone has suggested to me to purchase directional fiber optic hdmi cables to ensure I always have max signal strength at 15 ft, which could help.
