so what did you purchase? an air parrot? Ive not looked at one before..
i know others have fixed vga, Im not sure if it worked or not on my frineds, but you know HDMI works (hd3000 btw, you may have different)
I purchased Apple TV, turns out that since ML most don't need airparrot because of mirroring support.
I tried to fix vga, I get vga out when restarting with the cable attached, but the screen is distorted.
about the HDMI, I have NVIDIA and as I understand from this thread, the HDMI port is going trough this disabled card.
