I am running Windows XP Professional and I'm trying to get the dual monitor support to work. I have an on-board ATI graphics card and an S3 Trident adaptor in a PCI slot. Both cards detect and run fine. Although Windows works great whichever display I set as primary in the BIOS, They won't both work at the same time. In the device manager the secondary card is shown with an exclamation mark and gives the error - "This device cannot be started". I am also running Windows 98 on the same machine in a dual boot setup and the dual display feature on that works perfectly. I have also tried using Mulitmon (A program for using multiple monitors) and had no luck. Can anyone provide any input on this problem? Nick.

I have found that some of the video cards that would work with 98 and me will not work with xp from experiance. I suggest going here http://www.microsoft.com/windows/catalog/wcbody.asp?subid=22&catid=415c62ba-c636-4375-8ed9-ef2b19d5b67e and see if your card is supported. I have had the same problem and i have read about it in some xp books. Best if you want dual display to purchase a dual display card with dual outputs that is compatible. Im using a ati radeon ve dual display card with xp and it works fine. Good tidings to you.

This probably isn't going to help you much, but I'm running duel monitores with xp pro using a Matrox G450 Duel Head card and it works great. Sorry not to be of more help for your problem.

I am using xp pro ....I did have some difficulty at first but after I got the hang of it was fine.. I am using 2 verto 64 meg cards...compatabilty is mainly your issue...many years of experiance tell me to always use 2 of the same..now then since you are using a mismatch...I which I have in the past in a pinch...do the following put both cards in find out which one wants to priorty...after you idenify the priory card...boot twice...make sure you do...first boot is always going to be for the board bios..never fails...second boot is going to be for the bios on the card..trust me...after the second boot ...take your machine down into a cold boot ...install second card...due the same process...bios has a nasty way of doing an override...espically if you are working with AWARD...with an intel chipset......if you are using an amd chipset...defiantly...use the same cards...amd does not accommidate mismatch well...defiantly not if you are into the older bios....I work around alot of fcc equipment also...I can tell you from experience that one thing also that will affect video cards is high freq static waves from a tv...you may think its a driver or your system...and all it can be is a tv or the wrong Cat5 or 75 ohm cable running too close....I hope this will help...I know I rambled on some here ...but I am trying to make a point... thanks :)

I am using XP with A Gforce3 ti200 with s/video out. I have tried to hook up the s/video connection to my TV, along with my MAg 19" monitor, but I can only get one of them to work at the time????? any ideas??? Thanks

This is a trip... You can make your computer have dual monitor support without having to buy an expensive dual monitor port video card. I think those are a waste of money unless you dont have any available PCI slots on your computer. All you have to do is install an AGP card (if you dont have one already) and install a PCI video card, using PCI slot 1. In your bios, you will want to choose your AGP card as your primary card. This will most likely be in the peripheral/video card settings option in your bios. After your set this, the other video card will become your secondary card by default. You can also have more than two monitors if you have vacant PCI slots. Just install the additional cards in order from PCI slot 1 to the next PCI slot. Some cards will not be supported, however, these cards are basically older 2D cards that you probably will not be able to buy in the store anyway. Once you have done everything I've mentioned above, go to your display settings in the control panel, and the two (or more) monitors will be listed. Depending on your OS, there will be a setting available in your display settings to extend your windows desktop onto the secondary monitor. The AGP will be your primary card, so your PCI card will be the slave which will control the secondary monitor. Hope this helps.

I have been asked a question by a client on dual monitor support on thin clients. Is there a thin client out there that supports this.
