3rd monitor

I need to add a third monitor to my PC but not sure if it can be done so before I buy the monitor I thought I'd check here first and hopefully get some advice.

I am currently running 2 monitors, 1 of them is running off the onboard card connected to the motherboard, the other is connected to a 128MB PCI card which I purchased separately. I was told that if I wanted to run a 3rd monitor then I might need to replace my 128MB PCI card with a dual head type card. This question was put to the technical support guy who I purchased my machine from but he did not know for sure whether it would work!

I have 1024MB PC2700 DDR-memory (333MHZ). I take it this is enough to run 3 monitors?

Appreciate any help as I have hit a brick wall on this. I'm sure it can't be that difficult..

Thanks
Martin

Martin - no problem running a 3rd monitor. I do this on a PIII-667 with 576 MB RAM using a Matrox G880 dual head AGP card plus an Appian geronimo dual head PCI card in a spare slot, giving me the capacity to run up to 4 monitors. Not easy to set up, but that's what teenage sons are for! Chartman's your man for specific advice on this subject, and anything he recommends that conflicts with anything I have said should be given precedence.

Hi Martin
2nd PCI card should go in no problem you may have to manually assign PCI IRQ but thats easy to do.

if you want to have a test first PM me your address I can send you an old cirrus logic PCI card

I did ask the technical guy from Mesh Computers if I could just install another PCI card but he said there is no room for it which is why he suggested maybe replacing the one I have with a dual head card. Is he talking out of his back-side?

That's very kind, thanks. I just need to know first if I have the room for it in my machine. It's not even that my machine is that old, purchased it approx 7 months ago so I am not sure what the guy is talking about.

I'm sorry Martin, but I just had to laugh when you mentioned "Mesh" and "technical support" in the same sentence, but I won't divulge here the problems I've had with this nightmare of a company!!

However, I would agree with what your advisor said: sell one of your graphics cards on eBay (preferably the least powerful one), then search the eBay listings for a pre-owned Matrox dual-head card like RogerM uses. Do some research and you'll see you can pick up a powerful 2-3 year old card for under £40 that has 32MB+ of memory and hopefully 2 digital ports for sending a nice stable signal to your LCDs (presuming your LCDs can accept a digital signal!). Drivers are reasily available on the web.

An AGP card would be recommended because it works faster than PCI cards, although unless you're into gaming as well, you probably wouldn't notice any difference. However, check first how many AGP slots you have... some PCs only have 1, but have 4 or 5 PCI slots instead.

Manually assigning PCI IRQ's, as already mentioned by dc2000, is not that hard, but can be a hassle to get every card working properly. Often the best way is to just have 2 graphics cards from the same manufacturer in the one machine.

Oh, and after reading this reply, probably best to remove your address from the boards (Edit: ok, you've done that now ;) ). Then PM (Private Message) your address to dc2000. Best not to be so public with your address on forum pages. :confused:

Good luck and let us know how you get on or if you need more help!

Hi Martin
1024 DDR RAM souns like more than enough memory. I have 512 DDR RAM (PC 333) and have run more than 2 monitors. I don't think the PC memory capacity is a major factor influencing running multiple monitors. You just need to concentrate on getting the right combination of graphics cards and having the right number of sockets to plug the monitor into!.
It seems that if you install two cards by the same manufacturer (ATI AGP card & ATI PCI card) you are quite likely to experience problems - because the two cards share the same chipset. If you by individual graphics cards from seperate manufacturers (Matrox, Nvidia etc) things should run OK. Matrox and ATI definately do dual-head cards, some even do quad-head cards - so I believe.

Good luck

Okay guys thanks for your help. It looks like the best way is to get a 'dual header'. I will have a look around.

Now to find that third monitor to compliment my twin 17 inchers! I am looking for the largest quality screen I can get for under £1k. Any recommendations?

Cheers

http://www.matrox.com/mga/corp/home.cfm

scroll down to the bottom of that site and click one that suits u. The P750 is sufficent for runnign dual head. get a G450 if u want 4head.

In terms of computer power getting a high quality graphics card will do all the work on its own. The G450 may cost over 400 pounds, but is designed with 4 graphics card on one chipset, so that u can have different resolutions on different screens. Most corporate traders are using Matrox hardware.

www.dabs.co.uk is a great place to buy this kidn of hardware as most of the retailers only sell 50 to 100pic to corporate clients. Dabs.co.uk will sell u one with the lowest price avablilbe on the net.

RogerM - no posts have disappeared. Martin1973 posted the same question, with different thread titles, in Gen Trading Chat and the other in Techies Corner. You must have responded originally to one thread, then seen this thread which would have prompted you to question where the posts had gone to.

I have now merged both threads into one, and deleted Martin1973's duplicate posting.

I have experienced the opposite, hence why I wrote before about using 2 cards from the same manufacturer. Ok, hardware wise, it probably makes no difference if the AGP card is a Matrox one, and the PCI card is an ATI (or whatever brand) one, but different manufacturer's drivers running on the one PC can cause many weird and wonderful incompatibility problems.

Especially with ATI, who seem to have a knack of producing drivers which are "sticky" and need a good registry cleanout before attempting to installl another graphics card and driver!

For LCD ratings you can try here: http://www.reviewcentre.com/products93.html

I have never found Dabs that cheap when I have compared their prices. You also get stung by their delivery charges, especially if you are not on the mainland.

These people, however, do offer nicely-priced LCDs, and a good range: http://www.monitors-online.co.uk/ but no reviews.

Again, if you know what you want, and are not after the best LCD for graphics work (let's face it, financial information doesn't really require top displays!), then try eBay again. I picked-up a nice second display Iiyama 17" LCD, for all intents and purposes brand new and boxed, for around 25% less than retail. I just can't see the point spending massive amounts on a 3rd monitor which is not going to be your main display and doesn't need super-accurate colour or a fast screen redraw. You might as well buy a mid-range one and use the money saved for trading. But then I am a skin flint ;)
