Dual monitor support on Intel 815 motherboard?

Well, okay, I don't really know my motherboard's model... actually, it's VERY similar (if not the same) to the Intel 815EEA motherboard... however the setup program is different, so the user manuals I've found around aren't the ones of the mobo... anyways...

The motherboard came with a small AGP memory (named the GPU or something like that, it's like a kind of 4Mb cache, according to the manual) which I had to remove for adding the GeForce4 Ti 4200 128Mb AGP 8X with TV-Out.

So then, I wanted to have two monitors running, but no matter my tries in the BIOS, I can't make it so Windows detects the internal card again, even if I override it in the setup (Internal VGA device: Enabled), it still does not work...

The specs are a Compaq Deskpro EN with Intel i82815 graphics card, that GeForce one I mentioned before, 256Mb... etc. Well, some help here could be helping me how to make the dual monitor support work on here, or if someone could find me the real manual would be awesome, or if someone experienced could tell me if this motherboard supports dual monitor or not, and if it does, how to do it?

Thanks in advance :)

P.D.: I don't have the manual because the computer was a gift from a friend of mine... used comp, so it didn't came with manual :(
 
I just skimmed over this... It's not the motherboard that supports duel displays, but the video card. Basically any fairly recent video card supports two screens, either VGA and TV or VGA/VGA. Of course, that's VGA and/or DVI...

Anyway, so that video card should work. If not, you could probably find another video card to replace it for fairly cheap that would have duel display capabilities. I would say just get a second one, but rather than worrying about compatability between the cards and such, it'd probably be best to just replace that AGP one...
 
Well, talking with a friend of mine... he told me there are TV/DVI adaptors for using another monitor (so he's using two on the same video card, and it's the kind of thing I wanted to do) so I guess I could try searching for one. I thought by connecting a monitor to the internal and other one to the AGP one would work if Windows could use two displays at the same time but guess not here... :( I can't replace the AGP card - hardly I could grab my hands on this one... don't have a job and can't get one, not even allowance, so I'm stuck in money terms :P trying to do dual monitor with what I have, if it's even possible :P. Thanks for the info, though :)
 
Okaaay I'm back, looks like I'll be able to get some 16Mb PCI video card or something like that, but if I place a PCI here, it will disable the AGP one, right? or if it's possible to have the PCI work along with the AGP, how to do so?
 
I dont get this- your nVidea card should have two or more outputs on the back. You cannot have two video cards running unless you have SLI or Crossfire. You will connect both monitors to the one card you have.
 
@MrJack: LoL! old monitor that's not being used, and I wanted to give it some use :P

@Burgerbob: Well, this one doesn't - it just has one output, and a DVI connector, plus it came with a DVI -> TV female adaptor + one digital video cable (that one that looks like the PSX's one that you plug to the TV) so...

Dad told me maybe a PCI card or the AGP one or the mobo could be tweaked in some way so I could use the PCI for the secondary monitor, and the AGP for the primary... possible, too?
 
You can use several PCI cards if you wish, and most likely an AGP and PCI. But when you play games things will get messed up.
 
Yeah, that's what I've been reading... looks like I'll have to use a program or something like that for setting games to use a monitor instead of another.

However, I'm scared the sh** out of myself... when starting, the setup seems good.. I can do everything right - however, when starting, after the boot screen is about to finish, the primary monitor starts... left half of the screen vertically is black and the right half is orange... that's good.. bad... or normal... or do I have to put the PCI in another PCI slot (Currently I put it on #2, as in #1 is WAY too close to the GeForce's fan and I'm afraid it might overheat) or do I have to activate VGA primary device instead of S3 VGA as in the BIOS?... someone please answer, I'm worried about this orange screen of hell :(
 
:bump: anyone? I changed it to PCI #1 and after the second reboot after everything works, half black and half orange screen again... what the heck is going on?? :(
 
I have an intel 845G mobo, well it's a Trigem Glendale with an 845G chipset. It has onboard video, and I bought a PCI video card. With all the drivers installed, make sure you have all the newest video card drivers, and both enabled (I also switched the primary video card to PCI in BIOS) I could have both running wtih dual monitor and a TV - one onboard, the other and TV on the PCI card. When I ran games and such on the PCI card, the secondary monitor went a tad different, but nothign messed up. So what I suggest is get the newest video drivers, and to temporarily fix your orange screen, remove all but your primary video card. From there, download the newest drivers for your onboard and all other video cards, this is rather important.
 
Also, is half of one screen orange, or is it one screen normal and one oranage? Also if this is on that 4mb video card there is a chance it's somewhat broken or incompatible.
 
from my understanding of all of this, you have an AGP slot.

If so, then just grab this video card or something like it:

and use the DVI to VGA converter to run ur 2nd monitor. If you cheap out to something else, then make sure it comes with a DVI to VGA converter or just buy one for the 7 dollar waste they are to buy seperate. It's just a bad idea to use your decent regular AGP card with ur crap onboard, you mite as well spend the 50 bucks on a decent dual monitor supporting AGP card and be done with it.
