The monitor’s brightness and contrast are both set at 50% by default. I lowered them both to 35% to achieve a 100nit white. You should not increase the contrast setting above 50% as it leads to an increase in the level of green relative to the other basic colors and then to a loss of light halftones. The monitor’s brightness is regulated by means of pulse-width modulation at a frequency of 145Hz.

The monitor’s color gamut is indeed much larger than sRGB but only in greens. If you put a 2407WFP and a 2407WFP-HC next to each other, you can see the former produce a slightly yellowish green. The latter model yields a purer green. The color gamut coincides with sRGB in blues and reds just like on many other monitors.

Users have complained at a yellowish tincture of the image on the screen of the 2407WFP-HC, often relating it to the extended (towards greens) color gamut. This is not correct because the color gamut cannot affect the monitor’s reproduction of white or grays. If these colors have unwanted hues, pink or green or whatever, it is the consequence of certain flaws in the color reproduction setup. For example, I saw such a defect on the Hanns.G HG216D model before although it had quite a common color gamut.

As I said above, selecting a high contrast in the monitor’s menu leads to the appearance of a green hue in the picture. That’s why I don’t recommend you to use this monitor at a contrast of higher than 45%. If you feel the picture is too green on your sample of the monitor even at such settings, you should lower the level of green manually in the color temperature settings.


The average uniformity of white brightness is 5.7% with a maximum deflection of 21.9%. For black, the numbers are 4.9% and 17.0%. These are average results, especially for white where, as the picture above shows you, the right part of the screen is darker. On black, there is a brighter center of the screen but no brighter bands at the corners and along the edges of the matrix as are common for many other monitors.


The monitor’s gamma value is too low at the default settings: darks look lighter than they should.


It only gets worse at the reduced settings. The image is whitish, colorless. The monitor doesn’t offer a gamma setting in the menu, so you can only correct this by changing your graphics card settings or by means of hardware calibration.

The response time average is 6.6 milliseconds (GtG) with a maximum of 13 milliseconds. As you can see, Response Time Compensation technology helps PVA matrixes, which are traditionally considered slow, outperform TN matrixes with a specified response of 5 milliseconds.
