    So I am working on getting a Mac mini (late 2009) to output video to two 1080p 40" LG HDTVs. I had plugged it in and video filled both screens happily, but then something happened somewhere along the line of replacing the old setup with the new and when I plugged them back in, only one of the displays was filled (the one with the mini-DVI -> DVI -> HDMI) while the one plugged in with the mini DisplayPort -> HDMI adapter has a black letterbox all the way around. System Preferences says that both displays are set to 1080p, but if it is outputting 1080p, why wouldn't it work?

    I've tried swapping which TV is on which cable, so I know it isn't the TVs at fault. Ideas? Can the Mac mini actually fill 2 40" TVs?

    One last detail, the old setup was a Matrox DualHead2Go DP Edition adapter that had the two displays acting as one big display. We had to replace it, so I'm trying just using native ports.

    ----------

    D'oh. Dumb. I replaced the MDP -> HDMI adapter with a VGA adapter and it is happy now. Thought I'd leave this up in case anyone else ran into it down the road. Thanks anyway!

    A DP to VGA adapter doesnt put out the same quality of video as DP to DVI or HDMI.
    I get constant flicker on our larger panels with VGA adapters.

    I noticed that it wasn't as nice so I put in a little more time. Turns out all I had to do to get rid of the letterbox was check the box to "Overscan." Works great now. I'm glad even an old Mac mini can push out dual 1080p. Such a great little machine. :)
