    Hey guys, I'm having a terrible time finding a solution to this problem, so I just created an account here to see if any of you could help.

    I have a Mid 2010 17" MBP with a mini-displayport adapter, HDMI cable and Optoma HD65 projector. I was able to get my laptop to work on the projector once with this setup, and never again since then. Set-top boxes such as DVD players and game consoles running through HDMI work fine when plugged into the projector, but my Linux desktop, older Macbook and MBP don't work any more (all of which used to work through HDMI). I've tried lowering the resolution on my computer to 720p before plugging it in and forcing the projector to use HDMI to no avail. :( What am I doing wrong?

    Is there an error? Does nothing come up when you hit detect displays? etc..
