Amazon delivered yesterday so had to wait until I was back from work before I could open it up. Tried first to use the Display Port cable provided (well, the provided cable to a mini adaptor then to my 7970) but there wasn't any signal detected. Wondered if it needed configuring before it would work, so switched to the dual link DVI cable provided and that displayed fine
Switched it to native resolution and then went to paint and brought up a black screen. Luckily there didn't seem to be any white pixels showing, so I did the same with a while and coloured screen. Again, noting noticeable, so looks like I currently have no dead/stuck pixels.
Next, I used the settings on the first page to set the colour and then brought up the black screen again to check the backlight bleed. Thankfully, there wasn't anything that jumped out instantly, unlike the Dell U2713HM that I tried previously. There probably is some to a degree, but if I cant really tell the difference between that and the PLS glow then I'm happy. The main thing was that there didn't seem to be any changing of colours in the corners.
Fired up a few games, which I have been replaying recently as I've just got a second 7970 to crossfire. Went through Dishonored, DMC, Sleeping Dogs, Crysis 3 and Metro Last Light and tried to gauge how much performance drop I would get. I basically removed all AA, or left it low, and was quite pleased that I was getting pretty much 50s and mostly 60s, without any microstutter.
I'd come from a 1920x1200 24 inch so getting used to the dimensions of the PB278Q was the first thing to overcome. Nice to just have that much more screen to fill my scope of vision.
I did go back and try to use Display Port again, but no luck
Had a quick google and there seems to be a few people with that problem, but I might try and swap my 7970s around as on of them has a full DP port on the card, so might make that on my primary. Was hoping to use that as my main connection so that I could connect a separate machine over DVI but we'll have to see. I've read that its worth using another cable, but surely the one they provide should be good enough?
At the end of last night, I was just removing all the stickers, as I think that I will keep it, then I noticed the bottom bezel is very loose and that there is a gap probably in the central third, around the ASUS logo. Just wondering if others have had build issues like that? Its a little disappointing, and something that I expected from cheaper models, but I'm thinking that the panel is the most important thing. Its just a nagging doubt. Will try to add a picture later.
Not to end on a rubbish note though, its a lovely monitor, and happy with the panel, the manufacture date was January 2013 going by the sticker on the back.Shame about the build issue and the DP problem, but I'll have to spend a bit more time to see if its worth taking anything up with it. I'm also stuck between the settings in the first post and the sRGB mode - the whites just look whiter in sRGB, but time will tell I guess.
Overall, happy with it - lets just hope the whole monitor doesn't fall apart!
