Mac Mini, HDMI, no picture

Hey everyone... I'm helping a friend setup a Mac Mini to his Hitachi Plasma screen. We purchased a DVI to HDMI adapter and plugged in the mini to the TV. It looked great until we went into System Prefs. and clicked on Display. *As soon* as I clicked on it, the whole screen when blank and we can't get anything back. If I plug in a monitor to it, we get an image but not to the TV.

This is a 1.83 Duo Mac mini, 1GB RAM. This is his first mac and he's pretty irritated with it... you already know what he's saying. "I though Macs were easy to use." Of course, I'm more inclined to say the TV isn't working properly vs. the Mac but ya know. Any thoughts? Thanks!

This would likely be a problem with the Mac not getting a correct ID from the TV to allow it to set the appropriate resolution and refresh rate.

Try booting into Safe mode by holding the shift key down during startup. That puts the system into a basic mode and should allow the system to work with a standard display setting. You can then reset the display as it was before.

If that doesn't work, use the Find command in the Finder to locate 'windowserver' (no quotes of course) which should identify 2 or 3 matching files. Delete these and reboot with the monitor attached, so that it can then find the display and reset the preferences to that.

Adrian, once started in safe mode, when you go to set your resolution in the Display Preference pane (make sure you are doing this while connected to the TV, and NOT the monitor) be sure to click on the options button and be sure that "overscan" is off. On some Flat panels (like my Samsung LCD) the very same thing that happened to you has happened, and the overscan was the issue.
