I'm still struggling to decide if want a more upgraded 65 or a TCL 75.
You won't regret moving up in size. I have a 75 and am seriously thinking about an 83.
Right. In my life, I've never heard anyone complain about their TV being to large.
I currently have a ten+ year old, 80" LCD. I've been thinking about upgrading for awhile now. I'd love to have an 83" (or more) OLED, but the price difference between the 77" and 83" OLED is pretty significant. Plus, my HT receiver is on it's last legs, and I doubt it would allow 4k pass-through anyway, so I need to upgrade that as well. Guessing that's going to cost me an additional 2k.
