    Just opened my new U2713HM and connected it to an Haswell MBA, realized that I should use a famous hack to get a proper RGB signal out of the miniDP-DP cable, but the monitor is still recognized as a TV by OSX, why?

    What are you using to connect with?

    I'm guessing HDMI.

    Try a mini displayport to display port and it should work much better.

    You can safely ignore the icon. Check the resolution list, it lists 1080p/720p when the display is recognized as a TV.

    What about anti-aliasing and text smoothness? I find that small fonts look very thin...

    i have the same problem with my Dell U2414H.
    What hack did you use to get full RGB? How do you check if you have full RGB?
    Mine is also connected with mDP to DP.

    Here you will find the patch to get an RGB signal that you can double check in the system preferences (see my prev screenshot), and in the monitor menu where before the patch it would show YCbCr.
