A Look At QD Vision's Color IQ And The Philips 276E6 Monitor: Quantum Dots for Wider Color Gamuts

Display Uniformity

While measurements taken at the center of the display are one thing, the accuracy of images across the entire panel is another. Even if you have a display that is accurate in the center, large errors relative to that may mean that the display actually doesn't show a very accurate image overall. This can cause significant problems with video and photo editing, as it's necessary to use most of your display when doing those tasks to see as much of the image as possible. To examine uniformity, I've used our standard white, black, contrast, and color uniformity tests, which are all based on the patterns from the Gretag-Macbeth ColorChecker test.

White Uniformity

White uniformity is definitely not bad on the Philips 276E6, especially by the standards of $300 monitors. However, it's pretty apparent when using it that the left side of the display is significantly dimmer than the center. Depending on what sort of work you do this may or may not pose a problem, but for color-critical work the brightness variance is probably going to be too high.

Black Uniformity

Black uniformity is a bit all over the place. If you divide the display into two sections along its right diagonal you find that the top section is darker than the center area, while the bottom section is much brighter. This is again fairly visible when using the monitor.

Contrast Uniformity

Contrast uniformity is really just a function of the white and black uniformity. In this case there's an area of lower contrast along the bottom of the display, with the rest of the display actually being fairly good aside from a couple areas along the very top. It's just unfortunate that there's so much backlight bleed at the bottom of the panel, as that's really what's causing the issues here.

Color Uniformity

Color uniformity on the 276E6 suffers from the same issues as the brightness uniformity. This is to be expected, as if your luminance level is incorrect your colors will also be incorrect. Even when doing simple things like browsing the web you can tell that the left side of the display is not as uniform as the area right around the center, and it's quite unfortunate because as far as uniformity goes it's only the bottom left part of the panel that really hurts the 276E6's usability as a display for image and video editing.
