AOC Q2577PWQ 25″ IPS Monitor Review

Datacolor Spyder 5 Elite Testing

Using the Datacolor Spyder 5 Elite, we are able to consistently test the colour gamut, accuracy and uniformity, brightness levels and uniformity and contrast ratios.


Generally a monitor should have about 85% AdobeRGB once calibrated, however, it seems the factory settings were just as good as the calibrated settings; although it still falls short of expectations.

When testing the accuracy of the colours, Delta-E is the overall score. With an average of 2.23 when uncalibrated, the monitor is set up pretty well from factory. Once calibrated, the results drop to 1.22, that is seriously impressive, but I was expecting under 1 from this IPS panel.

Colour uniformity is simple, you want the colours displayed across the entire screen to be the same and as low as possible, under 3 ideally. If the numbers weren’t displayed, it would be hard to tell the charts apart. However, to the eye, the colours are more consistent across the entire screen.

Brightness Levels

Brightness is generally ignored to an extent, the brighter the better for image editing, but poor for movies and gaming as you have to turn the settings down to give the best experience. The differences between uncalibrated and calibrated is very slim, but the calibrated version just edges the win. It just goes to show that some companies can send out a very good display from factory.

Much like colour uniformity, brightness is ideal when it is the same across the entire screen. Again, as with Colour Uniformity, the differences are small but noticeable to the naked eye in the right lighting conditions.
