Deals seem to keep appearing for Vizio 4k tv's... also LG,
but the best pictures IMO come from the Samsung HDR and Sony HDR sets!
These prices don't drop like a stone often! I recently got the ks8000 series 55"
and the picture is pretty Amazing. It took me 3-4 hours looking at all the sets literally up close-- closer than you would normally look at them, from angles, etc. and the ks8000 series was my top choice, followed by the bravia 850d. Not even the overpriced OLED's matched overall quality, IMO-- maybe the new ones coming out this year would amaze me, but still, not worth paying a PREMIUM for!
So, in decending order:
Samsung ks8000 series
Sony Bravia 850d or higher series (non OLED)
Vizio hdr series (forget the model #)
Hisense HDR (8c is 8-bit hdr but still pretty impressive on a budget 1/2 that of ks8000).
Anything else, your not in HDR price range (or it sucks).. looking at ~$500+ for an hdr set topping out around $1150 for 55" +- depending on size variation. I look at the ks8000 as a long term investment. IMO, sets can not get much better than that over the next 5 years.. improvements in energy efficiency and max nits of HDR will come, but there will come a time when it's overkill on aging eyeballs. My generation had analog TV's and it twas good 'enuff. Our minds filled in the gaps. Perhaps that's why we see more ADHD in people. More is done for the minds' convenience so they don't work the same anymore!
