I haven't had a TV for 18 years. I used large monitors for a while, then when I moved 10 years ago I bought an 42" LG "digital signage" panel. They're the flat screens you'd see used for advertising, product display or notification in hotels, stores etc. They still sell them.
If I had to replace mine now, I'd probably get the 65UH5F-B, a 65" LED, 500 nits, 3840x2160, 60Hz, HDMI 3.0, DP, DVI, RS232, RJ45, IR.
Gross, 500nits willingly? Why wouldn't you just go for the standard 1000nits where HDR content is mastered for usually or 100nits where SDR is mastered for?
That's a hilarious opening question. I just watched an excellent Columbo episode from 1976 on a 10 year old LED screen, willingly, and I didn't even throw up.
