In many cases it is a problem of nVidia drivers. NVIDIA video card users try the following:

1. open the NVIDIA Control Panel
2. under "Video" select “Adjust video color settings”
3. under "How do you make color adjustments" select “With the NVIDIA settings”
4. under "Advanced" make sure "Dynamic Range" is “Full (0-255)” not “Limited (16-235)” (“Dynamic contrast enhancement” should be unchecked)

In my case it worked, anyway I don't understand why Dynamic range for video is limited by default...
