Been on my cx all year now, and my poor high end qleds never get touched any more. I have 3 Samsung qleds, a 2021 and two 2019 models. My LG CX OLED 70" is hogging my every free moment lol.
Differences from my anecdotal experience as well as personal friends and family hot takes:
Clarity - it's visually stunning in almost every setting. Movies, games, videos, hdr and non hdr. Noticably better picture in all comparisons.
Color - both normal and especially hdr color is far and away superior on the cx. Blacks are practically plasma level and I'm a bitch about proper blacks having come from a proper plasma screen prior. As for gaming, holy shit when dialed in correctly with a game that does proper hdr I lose my shit from time to time as does my brother and father lol
Movement and motion blur - being a self proclaimed cinephile, I am extremely picky about 24p, film grain, and all the different luts and blurs that go with my film watching. I know when it's faked, and when it stresses me out incredibly when poorly done. I'm happy to report when the settings are correct, it has the best proper motion blur of all my screens.
It's been a year of hard gaming from my self and kids as well as nightly movies and YouTube videos. 0 sign of burn in.
This is coming from a horrible experience with 3 previous LG b7s that had burn in in less than a year of use. I was super anti OLED 3 years ago. The CX has converted me 100%
