Monitor recognized as television

[Shockre]

Hi,
I have MacBook Air 13" 2012, OSX Mavericks 10.9.1 and just got a Dell U2414H monitor. Settings in OSD are: RGB color, Mac Gamma, sRGB color preset and in OSX Dell U2414H color profile. It is connected with mDP to DP cable, works good and image appears good, but it is recognized as HDTV by the OS. This annoys me and I am not sure if the OS sends full (0-255) or limited (16-235) RGB.

Here are a few screenshots:

I just bought one

Got mine in the post today too, same problem.

Do you need to put overscan on as well, to make it stretch across the entire screen, even at 1080p setting.

Found this

Forcing RGB mode has stopped the display coming up as a TV.
