I just ordered a 27" Qnix PLS glossy panel (Samsung version of IPS)- hopefully in a week I can update with feedback on this one.
As a follow-up, I have had this Qnix 2710 PLS monitor for several days now. It is indeed a very nice looking display. I would compare it favourably with my 27" iMac screen at work, and in its favour, a somewhat less reflective screen.
The bezel is a bit wider than those on my 24" Dell and Samsung monitors. The stand is fine- it only tilts and has a fixed height. It was a little too low on my desk, so I have inserted a 2" thick book under the stand to get it where I want it. The stand does not vibrate unduly and seems to damp out vibrations as fast as the 24" Samsung beside it.
I plugged it into my 650 Ti graphics card (Dual Link DVI cable included) and it was recognized automatically. The default color profile looks good and I tried a few profiles before going back to the default one. The colors look at least as nice as on my Dell Ultrasharp 2412 monitor, and better than on my older Samsung 24" screen. There are hardware screen brightness control buttons that work fine.
The included power brick is rated at 12V 5A DC (100-240VAC, 50/60Hz input), and although there was a Korean plug and an adapter provided, the brick accepts a normal north american power cable, so I just plugged in the one from my previous monitor. It does not get very warm during running, and has UL and CE approvals printed on it (I assume those are legit).
This monitor also has twin speakers in the back, hardware volume controls and a supplied sound cable- predictably the sound quality is poor so after testing that I have not used it.
The 27" (2560x1440) monitor (on the right) is only slightly taller than my 24" monitor (1920x1200) beside it- the pixel density is higher (the same as on the 27" iMacs), so text looks sharp though a bit smaller. You can see this below in a window that crosses the two monitors- the Safari window is about 1000 pixels high.
As far as dead pixels go, I did not order a "perfect pixel" model. I can see a single pixel (lower right corner, close to my trash can) that does not work- that is pretty good given that there are over 3.5 million pixels in total. The illumination looks pretty even to my eyes.
So far I am pretty impressed with this, and the bang for buck looks very good (I paid $315 US, shipping included). I bought this from "excellentcastle" on eBay, and they were fine. It was well packaged. The only assembly was a single screw to attach the stand base plate to the mounting post, and to remove the plastic protective sheets. It was shipped out a couple of days after purchase and received it one week after ordering, so no real complaint there.
