But when i use 3 asus vs228 lcd monitor it works perfectly fine by using this cables
mini display port - DVI
mini display port - HDMI

the cable setup for 3HDTV Since the TV doesn't have DVI Port

mini display port = HDMI
mini display port = HDMI
mini display port = HDMI

I have a similar problem, only my 3rd Monitor is a LED TV, I have to disable one of my monitors to use the TV as a display...

Also have Asus monitors (2)

Sorry I have no solution for this, just wanted to see if we could get some activity here.
