baka makatulong, sir itong RTINGS.com reviews... if you so believe on such reviews, also check their recommended settings/configurations.
https://www.rtings.com/tv/reviews/sony/x800ghttps://www.rtings.com/tv/reviews/samsung/ru7100I have the 49inch Sony x800g (2019 IPS panel) and 43inch Sony x800D (2016 VA panel)... parehas naman okay PQ niya either daytime or nighttime watching movies and Netflix/Youtube streaming. I don't find any issue with how they depict black levels. para sa akin, okay na okay PQ nila. on 4K HDR, both model produces stunning colors and very detailed PQ. I only do USB-connected harddisk when watching local/downloaded 4K/1080p movies via installed Kodi and SPMC. you could do some Android TV gaming as well. just buy a separate PS4 Dualshock 4 game controller =)
for Sammy RU7100, I have seen it in stores and they look good! but I haven't demo it yet using my movie collections.
basta sa VA panel mapapansin mo talaga degraded PQ niya starting at a certain angle. just watch directly in front of a VA screen.
as for LG IPS panel, try their 2019:
- top of the line NANO LEDTV: 55SM8600
- mid-tier NANO LEDTV: 55SM8100
i have the top-of-the-line 2016 LG IPS 55UH8500 too.
https://www.rtings.com/tv/reviews/lg/uh8500this tv gets very bright on HDR/Dolby Vision materials. watching on a dark room, it tends to produce a very obvious light blooming especially seen during the movie's end credits (when the background is purely black). but on normal scenes, you won't notice it either on lighted or dark room. and I find its PQ with stunning colors and it is very detailed. you'll easily get wowed with its PQ.
test them all and bring your own movie materials...
good luck!
