Monoprice IPS-Glass Panel Pro 27" LCD Monitor

As accurate as the post calibration numbers might be, to really be a professional display the Monoprice also would need to display good uniformity. If images looks different depending on where they are on the screen, that won’t work well for serious photo and print work. Before I even run the uniformity data I can see light leakage in all the corners that is very noticeable. I don’t work much against a black background as I do more spreadsheets and word processing, so I don’t see it as easily. If you watch a lot of movies or play a lot of games it will stand out more.

The White Uniformity is OK, but you can see the upper corners are dim while the lower corners are much brighter. The center of the screen produces very good numbers here but once you get to the edges some uniformity issues appear.

Black Uniformity really shows the scope of the issue. The upper corners have some noticeable changes, but the lower part of the screen really shows the problems in the uniformity. Black levels rise to be close to double that of the center of the display. Both bottom corners are bright and the left side has issues as well that can easily be seen. This is unfortunate but also a common complaint people have left in the reviews at Monoprice so I don’t believe it is confined to my sample.

These issues cause a big swing in contrast uniformity as expected. The two bright corners fall below 600:1, 33-43% lower than the center of the screen. The overall uniformity here is pretty poor and is the first place that the Monoprice display really shows its price point.

Those bright corners really cost the Monoprice when it comes to color uniformity as well. Most of the display is excellent, measuring very close to the center, but the corners really fall off. Two of them have average dE2000 errors of 2.0 or higher, so some colors will have visible errors, while the lower-left corner comes in at 3.17. Perhaps that corner will usually hold the start menu or some other, non-important content but it certainly won’t color match the center of the display.

If you’re able to use the Monoprice IPS-Glass Panel Pro and confine your critical work to the center portions of the screen you will see excellent overall results. Even for color critical work you’ll be able to use it without a worry. If you need that performance to extend all the way to the edges of the display as well then the Monoprice is going to fall short.
