Even though the Benq Zowie XL2735 and the XL2540 are not monitors meant for image processing, it would still be nice if they offer a somewhat decent colour quality. After all, games find some use in – for example – sufficient saturation.
First, we take a look at the coverage of the sRGB colour space for both monitors and are not disappointed. They might use tn-panels, both models use very capable ones that offer enough saturation.
Secondly, we take a look at the colour temperature of white with the standard setting. Both the XL2735 as well as the XL2540 perform well here, getting close to 6500 K.
For the colour deviation according to the CIE2000 norm we keep to the simple colour- and grayscale deviation. If you want to know more about the standard deviation and the individual colours, you can find them on the products pages of the tested products.
We see quite a colour deviation for both models, where the XL2735 is pretty severe at 5.65; at least the XL2540 is below 5. That said, the measurements were performed in the ‘standard’ setting – out-of-the-box both monitors are in a ‘gaming’ preset that has a lot bigger deviations.
The average grayscale deviation is not very small either for both models.
First in ‘standard’ mode, following that the out-of-the-box FPS1-setting.
Note that the gamma for both monitors is way too low in the standard mode, meaning detail loss in lighter image parts can occur.

As stated before, you do not purchase these monitors for image processing.
