Late to the party as always. My desktop is plugged into a 1080 Real 120 Samsung tv. I find at 120h is actually smoother than the 2/4K units that run at 60h.
Hdr has it’s benefit but I won’t give up the refresh rate to get it.
I have a little 720p lcd I use for watching vhs tapes. With the expand settings tweaked right old vhs tapes look real good and not like the squished mess we put up with on 4:3 televisions for all those years when it was “modified to fit your screen”!
