Mac Mini unsupported resolution question

Hi All,

Since the Mac Mini in question is currently functioning as a media hub connected via mini DVI to HDMI converter to a 1080i plasma, I originally posted this question in the Audio/Video & Home Theater forum, but it might also get some traction from different people here:

My tv has a native resolution of 1024x1080, which is not supported by the onboard video on the Mac. I've looked at two programs, SwitchResX and newscreen, both of which are supposed to be able to force custom desktop resolutions, but when running on Snow Leopard the OS seems to revert to the closest supported resolution.

Has anyone here faced this?
 
You should feed the plasma 1280x720p or 1920x1080i and let its scaler do the work. That's pretty much what your cable box is doing, just feeding it a common resolution and the TV does the scaling.

Your TV has more vertical pixels than horizontal?
 
Did you try my suggestion? Let me know. My plasma is 1024x768 and 16:9 (non-square pixels) and feeding it 720p worked for me. I did have some scaling issues, so I used SwitchResX to knock off about 10 pixels from each dimension.

If you insist on 1:1 pixel mapping, use the VGA input on your TV if it has one.

No VGA or DVI input on the tv, just HDMI, component, and composite. Here is what I did tonight:

I think I have partially solved this. My tv has a "picture format" mode, which was set to Automatic. I set this to "Wide screen" so that it no longer attempts to dynamically fit the picture to the screen. Once this is set, if I go to the Mac display properties and disable Overscan the Mac desktop shows completely in the screen, with a black border around it. This works for either 1080i or 720p resolution, where 1080i has more screen real estate whereas 720p has much sharper text.

This solution, I think, is "Good Enough(TM)".
