Cinema display and TiG4

[powertoolyzf750]

Hi, Plugged my 15" G4 laptop into my cinema display this morning and WOW - the screen looked like an acid flash back. Tried the laptop on another cinema display that was working fine and it was just as nuts! Re-installed OSX - still no joy? any ideas. It works fine as on it's own 15" screen - but not on the cinema display - weird and worrying!

Thanks

is this cinema display the new DVI models or an older ADC one?

it's the older one - but I think the problem lies with the lap top as it produces the same problem on another cinema display in the sam office when i plug it into that.
