I've owned TCL, Sony, LG, and Samsung 4KTVs. The only one I actually like is my Samsung QN90.
- The TCL got the dirty screen effect after a while and half the settings are hidden behind a goddamn phone app instead of in the TV where they belong.
- The Sony X950G last 1 month beyond warranty and suddenly ended up with a horizontal line across the center of the screen as if it cracked in half while watching a movie.
- The LG CX had the most annoying OS and issues of any TV I've owned, regardless of PQ. First off, it had a nasty HDMI bug that crashed all the ports until you do a factory reset. Never got fixed. Then the ADL had a weird issue where certain stupid bright effects (like getting hit with a wraith mortar in Halo) would crash the TV and make it reboot.
