I’m using this as the primary monitor for my PC right now and it’s absolutely stunning. Colors are accurate, off-axis viewing is solid, and it has tons of features for gaming (like G-SYNC). Not OLED, so reduced risk of screen burn-in.
I’d cheaped out and gotten a HISENSE first, but it had issues displaying text and I had to return it. I don’t know that I’d want to roll the dice on a factory reconditioned model, though. When I was digging into replacement monitors for my old 40" 4k Vizio (which I miss!) I was repeatedly warned by repair shops to avoid Samsung. A month in, though, and so far so good!
I see this deal is back up and can report that the TV is still going strong. No issues.
BTW Best Buy has the 85" version for only $200 more brand new. Plus they have 24 month no interest going on if you are in to that.
