QNIX QX2710 LED DPmulti True10 Reviewby Chris Heinonen on April 11, 2014 6:00 AM EST
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.
