Was also going to comment 8 bit + frc lol as far as im aware only Sonys 90 series and OLEDs have 10 bit
No I'm not it's 8bit +frc does this TV support Dolby vision?
When comparing my Sony 7002 to hitachi that was uploaded year last year (also 4K) we definitely noticed the difference. However maybe not a fair comparison as as Sony has HDR too, unlike the Hitachi that only had 4K
I know nothing about that issue but it clearly doesn't affect every Samsung TV else they'd all be returned! (ok, not all but return rate would be high). Common sense. LG for OLED, watch for RGBW models Sony AND Samsung - definitely Panasonic Hisense - good value for money, not high end ALL makes have pros AND cons, none are perfect!
XF85 looks great but with no reviews yet i'll wait b4 spending £1k on a bedroom tv for movies/gaming!
