This is my first real consideration for a 1440p panel, i have come across some games i enjoy that have become cpu limited cause of high framerate so looking to put the bottleneck back to my card with a quality monitor upgrade.
Looking at this monitor cause i hear much about it, wanting to go with the $370 pixel perfect model on newegg but looking for a little input about this monitor from any owners of 1440p panels especially the Qnix QX2710.
Some questions of course are how compatible are vesa 100x100 mounts with it, are 1080p and 720p quality video more blackbarred over my 16:10 panel or less?
I figured a 27'' 1440p panel will be the last monitor i purchase for quite a long time,unless 4k comes down to 27'' and single mainstream cards can play with a comfortable framerate.
I bought a pixel perfect version from Amazon (was supposed to be glossy but they sent me matte). I hooked it up and it was great (except for being matte), I got no dead pixels and it had no noticable backlight bleed. There is a chance of bad panels, but don't let A or A- fool you into thinking that every monitor has problems, that isn't how QC works. What happens is this:
The factory has batches of monitors, they select random samples to test. If a certain number of issues arise with the selected batches they "fail" the batch and rate them based on those test panels, assuming that it is likely that most of the batch is similar to those test panels. That means that 75% of the batch might be A+ but got rejected by Samsung or Apple or whoever it was intended for. It turns buying one of these into a *bit* of a lottery, but it's still not much of a risk. If you pay for pixel perfect all that gets you is grounds for forcing the seller to cover shipping for a replacement if you get a REALLY bad one. Which is complete luck just like with any monitor you buy. There is just as much chance of getting a really crappy Dell or Asus, no company tests every single monitor individually, it's just not price/time efficient. That's what the warranties are for.
The only real downsides to these:
1) no actual warranty, shipping to Korea costs more than the monitor. If you want a warranty buy a SquareTrade one. Otherwise be prepared to destroy it or throw it away if it breaks.
2) no OSD, you can't adjust settings besides brightness and contrast at all unless you do it on the software side of things. You can get ICC profiles from several forums (overclock.net has a huge thread about these).
3) No scaler, this means very little input lag, but it means you MUST run in 2560x1440p. You can run games in 1080p but you'll have black bars on the side and that isn't fun, it looks really bad. Running in 1440p means you need decent graphics power to keep FPS smooth.
I'm ordering a glossy model if anyone actually has them in stock (seems QNIX and XSTAR ran out) because I want to overclock to 96-120hz, but I've got two very very powerful graphics cards to keep my FPS high...
Final note: backlight bleed is usually pressure on the panel from the Bezel, if you're careful you can open the monitor up and fix it pretty easily with some electrical tape. There are guides all over youtube and overclock.net on how to do it. Oh, and to VESA mount you have to open up the panel and take the mount off or it looks really silly. The stand itself comes right off but the base of the stand is attached inside. The VESA mounts themselves are right on the back, couldn't be easier...
Edit: As for sellers, they are almost all the same. Green-sum was very nice with me, I ordered one he didn't have in stock and he refunded my order immediately when I requested it. He answered my questions and was pretty nice about it even though I was upset. ECOMADE Arena on Amazon is not a good seller, they sent me the wrong monitor and tried to deny my return and was very shady, even trying to bribe me to keep the wrong version. Amazon/Newegg are all resellers, so you don't return to those places...you ship back to Korea. The only benefit to that is you can open a case with them instead of Ebay. Honestly, no difference. I'm going to order my next from Hulustar on Ebay. If this one doesn't work out I'm going with an Overlord and I'll just pay the price premium. LOL.
