Despite modifying all the display settings (brightness, contrast, sharpness, gamma, color temperature etc.) of my BenQ XL2730Z, I can't seem to get an acceptable contrast, especially with grey colors. Here's a photo of my Macbook display from Google Maps:

As you can see, on the Macbook display, the roads appear fine (the contrast between the white of the roads and the grey of the non-roads is acceptable). However, on the BenQ display, it's like there's no contrast at all.
This happens in several other web applications (including Gmail) rendering the LCD display almost unusable.
