Need help making the choice

Hi guys,

I gotta get a new tv for my living room. The room is not super bright, I have shades I can close too. In the summer it’s moderately bright I guess.

I mostly stream movies/series and play PS5. Not sure if I’m gonna save a bit on 65” or get 75”/77”, depends how much money I can gather haha.

The models I’ve been thinking about and the prices

LG B5 65” ~1000€, 77” ~1350€

LG QNED92 65” ~805€, 75” ~1100€

TCL C6K 65” 799€, 75” not sure yet but propably 1000-1200€.

TCL C7K 65” 999€, 75” not sure yet about the price.

LG I can auto calibrate with Calman free of charge.

I’m open to other suggestions as well. I live in Finland if that helps

Thanks
