Okay. Got myself a TCL 85C7K (or QM7K in some other parts). The difference between C7K and C8K doesn’t seem to be mega large, and in some things the C7K seems to be slightly better. And for less money, I could get an extra 10”. Total light output is then still higher than a 75C8K.
It is indeed plenty bright at 3000 nits max, and more than large enough for my room. Image quality is quite excellent. Coming from a 55” G1 OLED, that’s pretty good. Contrast is excellent and I haven’t seen any obvious blooming yet. Overall, for a relatively budget TV, very nice. I was a bit scared about the viewing angles, but really it’s plenty for my seating area. Have it wall mounted, no visible cables.
