adding 3rd monitor

  • The help section says that you can have multiple monitors, but I can't get this to  work. 

     I have a dual monitor set up on my Dell 8300, P4/3.0/HT/800fsb board. I am using an nvdia ge force 5200 that came with it and it has a dual output, one dig, one analog.  I use an optional Dell offered adapter for the digital out to convert it to VGA. Works great, no configuring at all. I have 'screen spreader' enabled.

    I've been trying for hours to add a (known good)3rd monitor to my system and I can't seem to get any of the 3 diff video cards that I have available recognized. They are old spares, but they all work fine for running dual monitors in a compaq presario 98SE machine.

    In this Dell 8300, the matrox/compaq video card was ok in dev manager, but wasn't recognized anywhere in Display Prop/Settings. The S3 trio's 32/64's caused a yellow asterisk in Dev Manager and they also weren't in Display Properties. I tried all the t/s steps with each card , to find a solution, like updating drivers, the hardware troubleshooter steps, xp updates, and different PCI slots, #1 and #4 for all 3 cards and I'm out of ideas

    I read some where in the hours of troubleshooting/reading, that if you use a mix of an AGP and a PCI card, the PCI has to be in the #1 slot, and it will always be the primary. ( I wonder if I did get these 3 working, if having an old card with probably 2 or 8 megs of memory on it would affect the overall performance of the better card in the AGP slot) Maybe call this question #3 if it applies.

    I did try to find a HCL to see if the devices will be compatible in this computer, but I just get directed to the commercial MS site that has compatible devices for sale.

    I took out the agp card (5200) and the PCI S3 worked fine by itself Seems like a compatibility issue between the cards, but I hope there is a way to can get them all to work together. 

    ---------------------------------------------------------------------

    The short of it are these 2 questions:

    1. Is there a URL to pull up an HCL by vendor for XP ?

    2. Are there any issues that I haven't addressed in order to successfuly add the 3rd monitor ? Something in the Bios setup ?

    thx for any ideas

  • hi, thx for the reply.  I tried the one thing that I should have thought of earlier,  before

    all the r&r'ing, and it did allow me to use a PCI slot video card. 

    I changed the bios setting: primary video... AGP, to the only other choice,  which was AUTO.  This enabled the card to work. (duh!). 

    But....as I was asking about in the initial post, my performance seemed to sufffer using this card and I removed it for the time being.   One thing I discovered was that even though 'help' said it would become or needed to be,  the primary video card, when I checked in Display Properties, I discoved that the #2 monitor, (the one plugged into the anolog output of the dual AGP card),had made itself the primary, and also discovered the checkbox option, 'make this my primary monitor'. 

    So I ask the question again, do you think this old 2-4 MB card will affect the overall performace ?  When I get ahold of a more modern PCI card, I'll find out,  but a reply would be appreciated too.

     

    thx again and have a nice evening

  • oops, second question I would like someone to answer..............is there a HCL website where I can check a compatibility list for XP hardware ??  thx.
