Yeah, the second head is just a hack, basically using a chunk of memory to fake a second output, which means you can't do anything funky with it. Works well enough in most cases, though. > I am also lead to believe that these new fangled DVI video cards are capable > of driving two VGA plugs off of one DVI port; which means on a dual DVI card > you can run 4 monitors!

It's not something you get automagically, the hardware has to support it. The new Matrox Parhalia (or whatever) cards have one DVI and one VGA socket; you can plug a special cable into the DVI to let you drive two VGAs [1]. That's probably what you heard once. ;-) - Jeff [1] Which they think is very cool for playing FPS games and "reading PDFs and web pages, or large spreadsheets", which sounds like a hokey sales pitch to get business users to upgrade. ;-) Oh, they also do hardware-accelerated text anti-aliasing, which also sounds horrifically hokey. But I still have a love for Matrox. ;-) -- linux.conf.au 2004: Adelaide, Australia http://lca2004.linux.org.au/ "The Irish were next, being the only people who could credibly be accused of lowering the tone of a society of convicts." - Guy Rundle -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
