That's not a bad TV when calibrated correctly, I also get similar reactions when mot people still think PC's only use monitors. I was actually going to buy a 65 inch Samsung KS8000 last year but the LG TV I bought was for some odd reason returned to MicroCenter and I bought it open box for only 2K, not bad for an open box OLED TV. I love gaming on my recliner and since my gaming room is downstairs, it's always dark and that actually is good for my OLED TV since I only have the brightness set to about 25% along with a dark screensaver/desktop wallpaper that prevents screen burn. HDR helps make the picture look brighter while having the brightness and such lower.
I plan to rock this Stacker 830 for many more years since it's a full size tower that will comfortably fit any build including EATX builds with lots of breathing room. I may buy another one if I can find them so that I can assemble my retro then-overkill build being the old school QX6700 and dual 8800 GTX I bought back in 2006. Too bad my Dell Ultrasharp 1600p 30 inch monitor from back then is dead though. I still even have both the Logitech G15 and G5 and both still work good. I mainly game with an XBOX One Elite controller for most games since I'm more of a casual gamer these days and my wrist isn't very comfortable with a dinner tray on my lap when using KB/M.
well the only problem with my samsung is that that it has lots of input lag when not in game mode. So when it's in game mode it turns off all the calibration and I'm pretty sure it turns the chrome to 4:2:2 from 4:4:4 in game mode. For movies it's great and I also keep my brightness low as I'm in my basement too. I'm mainly setup in my basement because my home theater consists of 4 JBL L16's ( 2 way 8" speakers) and a pair of JBL L100's (3 way 12" speakers). These things are so powerful that I'm not kidding when I say I could run a small concert with them. I have them in my basement so my neighbors can't hear me. I know they can but nowhere near what they could if it was upstairs.
I, however have my TV resting on a 6 foot desk shell and have a couch in the back. I still sit about 3 feet away from my TV at my desk though. The thing is I always wanted a large setup but before the only was to do it was with a multimonitor setup and the bezels drove me nuts. This 65" is the same effective DPI at the distance I sit as Im farther away not to see the whole thing. but when I'm in productivity mode I have what is effectively 4, 1080p windows open. If I really need some space I can put it in a 3X2 configuration
