Older S3 and ATI cards are only supported as primary VGA devices in XP The work around is make the older card your primary in bios ... then you can change the settings software side. If you have multiple older cards however (like i do) ... though beans.

I am running into a problem with XP on a laptop running to an external display and the lcd. It recognizes both fine, displays both fine, problem being, I can't switch display I am using, it only displays on both. Not just that it wont display digital video on the external display. This stinks for two reasons, normally, when I running the external monitors I can switch the display to a much greater resolution, as well as it is a much better monitor than the poor old lcd on my laptop. Has anyone run into this? This has worked on every version of windows (9x,2k,and beta releases of xp) until this final release. Microsoft states that the hardware is does not support this, which I have proven wrong with every other OS. I am running FOSA Extreme 8900 Laptop PIII 700 512MB pc100 memory 2 @ 30GB Hard Disk Drives It's running the ATI LT Pro video chipset w/the video input (for capture) and video output. It's the Intel BX Chipset WinXP 2600RTM Any Ideas?

I had the same problem with an ATI Radeon 64Mb and an old PCI RAGE 3D, to fix it, set it to boot from PCI in the bios, that's worked for me, I don't know about 4 monitors, this is only with 2, I had another question if anyone can help, with this dual monitor setup I'm trying to watch a movie of any format, DVD, VCD, AVI, or whatever but the only way to full screen on the secondary display is to make it the primary. I'm wondering if anyone knows of a program that lets you play video files full screen on a secondary display.

Kalidor got it spot on! Thanks for the advice - select the old PCI as primary in the bios and multiple monitors works a treat in XP home. Thanks again Kalidor.

I'm having the same problem with my system. How do I select my PCI card as primary in BIOS? I'm assuming this is easy to do, just need some instructions. Thanks

Matt, regarding your question about multi-monitor video players - there's a great one (IMHO) called Zoom Player. Its learning curve for the advanced options is pretty steep, but if you're lucky, you might be able to just move the window over to the monitor you want it to display on and hit Alt+Enter. If that doesn't work (like, the video is too big or too small for the screen, when you're running your displays at different resolutions), you'll have to fumble with the "zoom presets," which you can cycle through by just hitting the numbers 1-0. Hope this helps!

here is something from microsoft website: The information in this article applies to: Microsoft Windows XP Home Edition Microsoft Windows XP Professional ---------------------- SUMMARY The following adapters are supported natively in Windows XP as secondary display adapters or Dualview adapters: Desktop Computer Display Adapters for Use with the Multiple Monitor Feature 3DFX Banshee 3DFX Voodoo3, Voodoo4, Voodoo5 3DLabs Permedia2, Permedia3 ATI Rage128, Rage128 AIW, Radeon Intel I810 Matrox Millennium, Millennium II, Mystique, G100, G200, Productiva, G400, G450 Number Nine Imagine 128, Imagine128 v2, Revolution 3D, Revolution 4 Nvidia NV3 (Riva128) Nvidia NV4, NV5 (TNT, TNT2, TNT2, TNT2 Ultra, TNT2 Vanta, TNT2 M64, Geforce, Geforce3) SIS315 so my question is: Is there anyone who can hack a fix for this lazyness of microsoft before I go back to win98 when everything worked

Same problem here, older video cards. I think this tiny number of video cards that do dual view is part of a big plot of MS's to make money or do something underhanded. Why would win98 support more video cards for dual display than winXP? I am not sure what, could be lots of things. Anyway, I hope someone tells us how to get around this quick. Bob, you say Win 98 will do dual view with most video cards? thanks all, psol
