I picked up one of the clearance ones too, but haven't opened the box yet. It looks like a return as the top is sealed with packing tape and one of the box sides has a small hole in it. Going to try it out tonight.
What's the picture quality like on yours? Also any backlight bleed or other nonsense?
Got mine new in the end. I have mixed feelings about it so far, but I don't really want to taint your first impressions of your new screen, so perhaps don't read this until after you've got it running.
...
Pros:
No problems with brightness, I have it turned down to 20ish. The colours are great, as you'd expect from an IPS. Contrast seems good. No discernible flicker. The matte coating is really good -- LG have improved on this massively in the 8 years since I last bought (and returned) an LG.
Freesync is great, probably a must-have for me now. The monitor can be run at 75 Hz without using freesync as well, which is nice.
Cons:
The stand is pants, as discussed, but unless I really give my desk a thump, I don't notice it moving. Its too low for me, and would require a very sizeable book to lift it.
Mine has some bleed in the bottom left and top left - it isn't the worst I've seen (Samsung T24D390 takes that prize) but it does combine with the glow out at the periphery to be quite noticeable in the evenings when the light is lower. I'm snobbish about this so am on the fence about whether to return it and try again, make do, try a different model, or abandon IPS altogether.
I tried Arkham City the other night and there was something unsmooth/unclear about the picture during movement even at 75 fps. It wasn't frameskipping, vsync was on, and it didn't seem to be stutter, so I couldn't work out what the deal was. Last night in ARMA3 (looking out a window, so dark surround, bright centre) it became clear that there was a lot of ghosting visible. I've never noticed ghosting before. I still can't say for sure whether it is the screen or my eyes, but I think this might be why fast movement looks ugly. I'm going to try and get my camera working today to get some fast shutter speed shots and confirm this. And perhaps there is a setting that will fix it, although I think I've tried them all.
The specs say:
Response Time_Typ.(on/off) = 14 ms
(GTG) = 5 ms
So it claims to be fast, but is GTG actually a standardised measurement?
