Mac losing display through hdmi matrix....any ideas

["noel" <noel@xxxxxxxxxxxxxxxxx>]

Hi all,

I'm hoping some of you may have experienced this and have a fix for me!!

I've just installed my MacBook pro into node 0, running the dvi output to a
dvi-hdmi adapter and into a 4x2 hdmi matrix

The second source into the matrix is an apple tv.  Just using this for
video only with audio being handled separately.

Outputs of the matrix are my lounge projector 720p and a bedroom LCD also
at 720p

Problem I have is if i switch the matrix so both screens are watching the
apple tv ie no display routed from the mac then the mac 'loses' the
external display so when i select the matrix to show the mac again the
projector/tv show no source.  I have to click detect displays on the mac to
get them to pick them up again.

If I use the matrix to keep one display on the mac then when i switch the
other back all is fine.

So I need to find a way to ideally have the mac auto detect the displays or
find a solution to the problem?  It's not likely to be a massive issue as
the apple tv will get minimal use but it's annoying so I'd like to resolve.

Thanks all

Noel
