You got 720p,1080p, 4k. More pixels. Doesnt take a fuckin brain genius to figure out if your tv's picture looks better because of course it does, and you don't gotta do anything to get it to work. but they realized that past 4k, shit ain't gonna look much better for the cost. so what do they do? more colors per pixel. only problem is color settings on tvs suck. tv manufactures handle this like dogshit. so now you gotta spend 30 minutes before watching a movie cause your fuckin tv automatically changes the setting from time to time for no fuckin reason. all this just to get slightly more colors. it's not even that noticeable. i fuckin hate HDR. i fuckin hate tv manufacturers.
the shining's still a beautiful movie but fuck me did i not notice the HDR one bit.
Not sure if my tv is just too cheap or if it's not intended to be used with subtitles, but it ended up making subtitles dim in some areas and was really distracting.
Interesting, what model? I never thought much about it but I could definitely see that being a thing. Outside of OLED tvs, one of the big problems you run into is light bleed because unlike OLED tvs where every pixel is individually backlight, most tvs have much larger zones. if the algorithm isn't sophisticated enough to account for it or it doesn't have many zones that could be an issue.
Vizio M-Series 50" has 16 local dimming zones, I'm sure there are other/better options but I got it from Costco last year on Black Friday so I have no intention of getting something else for another 4-9 years.
