I inherited a G4 MacMini from my mom after I gave her an Intel MacMini.

I've installed Leopard on it, and it works very well. I was initially
going to use it as a webserver, but have found it perfect for a second
computer at work.

However, I am having issues with getting it to drive a monitor properly.
I have two monitors, both which do 1920 x 1080, and this is just within
the maximum resolution of the MacMini (1900 x 1200).

I can select the appropriate resolution (1920x1080) but when I connect a
monitor via VGA using the supplied DVI to VGA adapter, there is a black
border on the left hand side, and everything looks squeezed up and
slightly blurry.

If I connect the monitor by DVI, it normally displays nothing (no
signal) but if I plug and unplug the DVI cable, the image appears
perfectly. However, if I do things like scrolling through a document,
the screen starts flashing (goes blank for a second, then reappears),
and there seems to be associated 'static' when this happens.

I've tried two different DVI cables, one of which appeared to have all
the pins connected, plus a DVI to HDMI cable, but this has made no
difference. It doesn't appear to be the monitor as I've tried both, and
they are different makes (Fujitsu and Ilyama).

I suppose there may be a problem with the VRAM of the ATI graphics (all
32 megabytes of it!), but it's odd that my mom didn't have a problem,
though the resolution of her screen was lower (I think it was 1400 x 900
or something like that).

Any ideas?
