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.

HD refers to 1280x720 so it logically follows that QHD refers to 2560x1440. Look at some laptop spec sheets, they all claim HD for 1366x768 and Full HD for 1920x1080. This review is not confusing in any way, it just sounds like you guys weren't very familiar with the terminology (which is admittedly kind of confusing).LordOfTheBoired - Sunday, April 13, 2014 - link
The terminology isn't confusing. It's stupid, and it always has been. The *GA line isn't any better(it's actually far worse, for various reasons).Specify resolution with a perfectly good X by Y spec, or don't bother at all. Leave the cute nicknames on the mass-marketing bullet lists where they belong.

HD = 1280x720FullHD (FHD) = 1920x1080
QuadHD (QHD) = 2560x1440
UltraHD (UHD, 4K) = 3840x2160
The confusion has come in when people have begin referring to 1920x1080 as "HD". By that definition, "QuadHD" then implies 4x1080p or 4K, which is incorrect. QuadHD has always been 2560x1440. So the confusion doesn't come from how the article is written - it comes from the incorrect definition of "HD" that has perpetuated over the last few years as new confusing acronyms are coined for higher-resolution displays.

The confusion comes in when people refer to the vertical resolution for years and years (480p, 720p, 1080p) and then switch to using the horizontal resolution (2K, 4K), especially considering those monikers are off by several hunder to a thousand pixels.If everyone just keeps using the vertical resolution, then nobody gets confused.
480p
720p
1080p
1440p
2160p
Nice, neat, simple. Changing definitions in the middle is what's causing all the issues.

4K sounds way cooler though. and when it sounds cooler, it sells more. kaching!skifiddle - Sunday, April 13, 2014 - link

Panel grading refers to manufacturing defects, these ebay panels are usually B grade on a scale of A+,A,A-,B,C. Also WQHD is 1440p as the keywords, article, charts, and text state...blackoctagon - Thursday, May 1, 2014 - link
They're not only sold on eBay and the panel grade is actually A-
