QNIX QX2710 LED DPmulti True10 Review
by Chris Heinonen on April 11, 2014 6:00 AM ESTDisplay Lag, Power Use and Color Gamut
Measured using a Leo Bodnar lag tester over HDMI, the QNIX has 33.3ms of input lag. This is likely going to be too high for most people that want to seriously game on the display. There is no game mode or anything else to reduce this input lag, though as always using a native resolution might improve the situation. This might only be by 2-3ms and so it might not make a huge difference to people.
The QNIX color gamut encompasses 69.1% of the AdobeRGB gamut. This is slightly short of the sRGB gamut (which is 71% of AdobeRGB). The shortcomings are going to be in the Cyan and Blue area of the gamut as there is over-saturation in Reds and Greens. With standard white LED backlights this is expected.
Power use is average for a 27” QHD display. The maximum light output power usage is very close to everyone else, but the minimum power usage is a bit worse. Since it is only a couple of watts difference here, it isn’t a large enough difference to even worry about. The QNIX is neither more or less efficient than other LED backlit displays on the market.

"At a time when a $700 monitor was considered cheap in the United States, these were available on Ebay for around $300 and utilized the same panel as more expensive offerings, though often with a lower grade panel."What's confusing about that? Several years ago, the cheapest QHD panels in the US cost $700+, but you could find a Korean brand display off of eBay for $300. They used the same panel (as there are only a few companies that actually manufacture LCD panels -- AUO, Chi Mei, LG, and Samsung are the biggest), but panels are also graded on quality as well. So the same panel out of LG will have a set resolution and generally similar characteristics, but if it's not very uniform or has a few dead pixels it would receive a lower grade. The shortened form of this explanation given in the article is due to the fact that this is all generally common knowledge, so we don't tend to go into a lengthy explanation every time we talk about a display.
And as to the 4K vs. QHD aspect... sorry if you're not up to speed on acronyms, but QHD has always been 2560x1440. QHD+ is sometimes called 3K (but there are multiple "3K" resolutions) whereas 4K is generally referred to as UHD (and again, there are multiple "4K" resolutions). Here's a link covering nearly every commonly used resolution: http://en.wikipedia.org/wiki/Graphics_display_reso...

I hardly believe insulting the readers is the best way for one of the authors to express himself. It's unprofessional and goes against everything I have read or heard from Anand when he refers to the readers.Yes it's true that not everyone who reads this site is familiar with all of the terminology, and in this case the terminology even stumped Google because the first thing I did when I came across QHD was a search and the first result was the 2160p article on Wikipedia. Perhaps referring to the vertical pixels early on would have been helpful in this case, because a number (1440) is a lot harder to confuse than letters when describing the number of pixels on a monitor.

Since when did stating FACTS become insulting? Get your terminology right and there will less "confusion"brucek2 - Monday, April 14, 2014 - link
"Same panel" and "lower grade panel" appear mutually exclusive to a casual reader or to a literal one (with the latter heavily represented here, I bet.). A lower graded panel of the same model family is still not the "same panel" anywhere outside of a used car lot.At best this was a sloppily constructed sentence and more realistically it was unnecessarily confusing to a lot of readers.

2560x1440 panels are called QHD, while 4K are called UHD.By grade, the author means that they are not rated A or A+.
A panel with a defect, like a dead pixel or a tiny scratch is rated below this, and OEMS like Samsung or Apple won't accept them. Local companies buy them and manufacture monitors like this.

quad hd means 4 times as many pixels on the screen as 720p ie 1280x720 (921600 pixels) 2560x1440 (3686400 pixels) is quad hd. 4k is a stupid misleading term.jaydee - Friday, April 11, 2014 - link
Could you please review the new Microcenter Auria EQ276WN?dylan522p - Friday, April 11, 2014 - link
Pretty much same panel and monitor.QuantumPion - Friday, April 11, 2014 - link
I have an X-Star DP2710 and my results are quite a bit different from this review.-My model is the DVI-only version which I got because they supposedly have lower input lag. I don't have a way of testing the input lag, but I have not perceptually noticed any, coming from a 120 hz VA LCD previously.
-My model has no OSD, only brightness up/down buttons.
-My model overclocks to 120hz, however overclocking severely affects the gamma and contrast.
-Similar to the article, my panel has bad uniformity issues and only average contrast.
-My model has nearly perfect gamma calibration right out of the box. This monitor has the best default calibration settings I've ever seen. I don't have a color calibrator but this guy's review indicates similarly that these panels have excellent default color calibration: http://www.youtube.com/watch?v=0EMmNmvFcAA
I wonder if I just got lucky and got a good batch, or did they change their product since last year or what.

These are low grade panels. There's probably a lot more variation between individual screens than with a Dell or Apple branded monitor; never mind professional level NEC or Eizo monitors.
