QNIX QX2710 LED DPmulti True10 Review
by Chris Heinonen on April 11, 2014 6:00 AM ESTDisplay Uniformity
The uniformity of the QNIX display is where we really start to see the cost savings become visible. As I've found when looking at the ultra-wide displays, the taller the monitor the harder it is to get a backlight uniform to within a certain tolerance. If you have a larger tolerance, it will be cheaper and easier to manufacturer but you'll have less uniform backlighting. This is why professional monitors can be so expensive, and it's an area where it looks like QNIX has managed to save on costs.
Looking at the black uniformity, while the two top corners have a large drop-off in light level, the lower right corner is quite bright.
Looking at the White Uniformity, the same drop-off in light occurs here. Somewhat surprisingly this fall-off occurs in the bright corner as well. The center measures in at 198 cd/m2 but most of the panel drops off below that. Corners fall as much as 22% which is clearly visible if you look for it. If a monitor is within 10% it is hard to tell the difference I find, but once you get to 20% you can notice it when you are viewing something that uses the whole screen.
This causes the contrast on the whole panel to max-out at 750:1. In the corners is can fall as low as 468:1 which is a rather washed out appearance. Overall the contrast is fairly consistent, but the contrast of 750:1 isn’t great to start with.
The real issue is the color uniformity of the QNIX panel. While the center is fine, the edges have visible color shifts. Since we consider a dE2000 error level of < 3.0 to be invisible when in motion, but only 1.0 when looking at still images, these are errors you will certainly see. When it comes to using the QNIX for photo editing and other color critical work, it really won’t work well because of these uniformity issues.
The uniformity is where the QNIX really falters. It’s the first display with color uniformity errors that fall into the red zone in multiple regions. This could be just my sample, or it could be that the tolerances are lower for backlight alignment, allowing more monitors to pass inspection and lowering prices. I can't be certain but it seems that uniformity is a major area where costs have been saved.

This is the model that QNIX had available for me to review. None of the other models have been made available for review to this point.okashira - Friday, April 11, 2014 - link
Whoa, I just noticed a huge mistake in the article. This monitor can NOT be overclocked beyond 60Hz.It will accept high then 60Hz input, however, it will only result in skipped frames and poor juddery movement.
Stuck with the DP2710LED or QX2710.

WHy is anand deleting my comments?This monitor is one of the worst of the Korean's. The DP2710LED and the QX2710 are superior.
Also, this monitor is not overclockable. Over 60Hz and it just drops frames. Bad information.

"WHy is anand deleting my comments?"We haven't been deleting any comments. As far as I can tell, all of your comments are present and accounted for.

Yep, sorry about that. I thought comments were sorted by descending date.Badelhas - Monday, April 14, 2014 - link
Ryan, please buy the single dual-DVI input and test it. That is the Korean Monitor you should be testing, not this one ;)Laststop311 - Friday, April 11, 2014 - link
If you keep an eye out on craigslist you can find really good deals and people will usually negotiate. I got a dell u3014 2560x1600 and I only paid 625 including the gas to drive and get it. The outer bezel had some scuff marks but the panel performed flawlessly. It was still perfectly calibrated, almost perfect uniformity and it ran very cool to the touch compared to other monitors.Yes 625 isn't as cheap as basically close to 400 after all is said and done getting a korean monitor. But this is 16:10 and 30" with more pixels. When you are only saving that much though is it worth the risk of dead pixels and crappy build quality and questionable longevity. Keep an eye on your local craigslist's for high end monitors. This is where you'll find the best deal.
I'll be sticking with the dell u3014 for a long time as the only upgrade i can look forward to is one of the 32" 4k UHD monitors and they are way overpriced for quality ones.

That was a good deal. At the time I was looking at 1440p monitors, 30" 1600p ones were still going for 750 to 900€. I got my Samsung one for 540€ because of a discount. And besides the refresh rate, it is a super great panel with the right amount of anti glare. I'm looking forward to a 4k model in a year or so, when 60Hz and compatibility of good. :)pierrot - Saturday, April 12, 2014 - link
so the version with less inputs should be just as good in the other areas right?cheinonen - Saturday, April 12, 2014 - link
There's no way to say at all how it would perform. The firmware is different, and as we've found before (look at the two LG 29EA93 reviews), a firmware update can make a monitor completely different. So the panel might be the same, but that's just one part of a display.
