He is talking about for desktop use.Only looks large a few days then you feel you should have got larger.
Today if buying I would be looking at 65" min but look up the ideal viewing distance for 4k in my room its like 100", most are sitting too far way for their screen sizes so may as well be 1080p, same as when 1080p came out as I grew up when we sat across the room from a 20-32" SD CRT.
for me anything over 40” would be way too big. 32” is ideal.
