Terry,
I'd check with Dr. Bott (http://www.drbott.com/prod/db.lasso?QuickSearch=gHead) about their gHead product. It is a $20 VGA adapter that fools the computer into thinking the monitor can do every resolution there is. I think the 1024 x 768 resolution would then stick. Your AppleScript might work with this setup.
Most people use the gHead for Macs that run headless or with a KVM switch so they can run Timbuktu, or something similar, on it. They are very helpful and would be able to tell you if it will work for you or if there is another solution.

Hi all,
I have a severe problem with a Mac Mini I bought and I hope someone can help me. I am sorry for this off-topic post, but I wouldn't know who else I could ask.
I made an application in Revolution to display texts on a LCD projector. I previously used a mediaeval Windows laptop to run that on, but it responded way too slow. So I bought a Mac mini 10 days ago and tried it. But it didn't work. I called the Apple helpdesk and they didn't have a clue. I got some tips on other lists; some useful responses but still the problem isn't solved.
The problem is (probably) that when the Mac detects a monitor it hasn't known yet, it defaults to the 800x600 resolution during startup. But the LCD projector accepts only 1024x768 or higher. Because the previous monitor used a 1024x768 resolution it starts with that. So first it shows the grey Apple logo with the spinning wheel. But then it detects the unknown screen and defaults to the unsupported 800x600 resolution, so the screen turns blue. Because the Mac Mini only can use 1 screen at a time, I couldn't think of a way to change the settings without being able to see the screen.
So do any of you know a solution to this problem? Are there 'hubs' to split one VGA signal into two 'screens' (that both display the same)? Is there a way to change the default settings to a higher resolution?
I tried an AppleScript that ran on startup to change the screen settings automatically. The script worked with my test monitor; not with the LCD projector. Others suggested to boot the Mac Mini without monitor and then connect the LCD projector. No result. I also heard that hitting F7 might help. Nothing. Also booting with another monitor, switching to 1024x768 and then connecting the LCD projector didn't work.
Any other suggestions?
Terry
