Mac mini to Projector connectivity

[Zirax]

I have a mac mini which is being used to output to a projector (1024*768).

Now the cunning plan is to run an HDMI cable from the projector to a media point in the wall. Then you can have a splitter for xbox, blu-ray, mac etc. The snag that I have hit is with the connectivity for the mini.

Previously I had this setup which allowed me to output a higher than native signal (PJ downscaled but had a cracking picture):-

Mac (DVI) -> (DVI to VGA) -> VGA lead -> (VGA to M1) -> Projector

Now I have this:-

Mac (DVI) -> (DVI to HDMI) -> HDMI lead -> (HDMI to M1) -> Projector

The upshot of this change is that now the mac mini talks directly to the projector as it see's the connection as a DVI connection. This has confirmed two things:-
1. I really need to setup the colours properly when using VGA. There is a 3200MP profile under DVI and the colours look great.
2. The mac locks the output to the native res (1024*768).

Obviously this now means that HD films get squished in 720p and look a whole lot worse with the software compression.

Idea

The solution that I can think of for the mac mini is:-

Mac (DVI) -> (DVI to VGA) -> (VGA to DVI) -> (DVI to HDMI) -> HDMI lead -> (HDMI to M1) -> Projector

Not ideal by a long shot but stops the mini from locking the res to 1024&768. The projector in question is a Dell 3200MP, which does actually take an HD signal (scaling applied).

Anyone have any ideas or ideally how I can force the mini to output a non standard res signal when in DVI?

HDMI needs a digital signal path, which disappears when you do DVI -> VGA. In short, you'll get nothing - nada - zip - no picture at all apart from the very helpful words 'no signal'.

Try SwitchResX (http://www.versiontracker.com/dyn/moreinfo/macosx/15467) instead. I think that's what I used when I set up my Mac Mini. My KVM doesn't understand 16:10 resolutions and so doesn't send the DDC for them to the Mac, so I didn't get the resolution I wanted.

Caution! This tool uses the dreaded APE. Do not - I repeat - do not - attempt OS X upgrades with this installed. It will fubar your system. Updates seem fine but be careful - APE has a habit of hooking into undocumented things, and since they're undocumented, Apple can (and will) remove them. How very kind of them.
