I use a 42" and a 40". Currently still trying to get dual screen working for hackintosh but it's been a blast on win10 and ubuntu. Crisp and clear.
I use a Samsung 40 UHD TV the real annoyance is I have to turn it on with a remote it does not sense that the computer is now in use like a monitor does. I love it, have one at home and one at however my video card died and I am using Intel 4000 graphics which means 2k, its the suck but I have an old i7 system that cannot handle Sierra, and an unwillingness to pay the prices for a replacement GT 970. I am going to do a new build as soon as High Sierra is out and iBoot and Multibeast are updated. At that point, internal Intel graphics will be fine and I can upgrade to a video card later.Anyone here use a 40" HDTV as a monitor?, and if so, what do you think of it as far as a monitor goes?
