Are you running the 50" at full res (3840x2160) @30hz over HDMI?
From my understanding HDMI 2.o will support 60hz w/4k but the current HDMI standard doesn’t and hence the 30hz.
Also, how does the text look!?? No sense in going 4k if I can’t read what’s on my trax…lol
ftr, This Seiki does support 120hz at 1080p… very tempting and wondering if a firmware upgrade would be feasible when HDMI 2.o the standard comes through…
