I have a tcl 4 k with out HDR its very good screen. Cheap Samsung, like Volkswagen is to a Skoda.
The new LG 4 k did cost twice as much $1200, but has Dolby vision and 3 types of HDR, The panel is awesome Dolby has 12 bit stream against HDR 10 bit. 120 Hrz motion refresh and the cpu power is much better. Its faster between applications. Connected by optical to a 5.2 system. The Pioneer system has no hdmi, would have used the arc instead.
Strangely music sounds better when playing from a out side disk to the usb 2.0 then from the computer trough the hdmi. Maybe the tv has a better decoder the the hd realtek that the computer has.
