Purchased the q90t. Old tv was lg c8, but I wanted to try something new. Also, the c8 doesn't have hdmi 2.1. Found out quickly that hdmi 2.1 is pointless w this tv. Hdr w vrr enabled on series x gives a washed out look...also, the tv dims by itself even w game mode off n none of the eco stuff enabled. Returning it tomorrow n will probably pick up the lg gx instead.
