Solve : Multiple monitors issue?

Answer»

I remember having a nice option on one of my older computers

I could physically connect 3 monitors, but the card only supported 2, so I could select what ones to use without restarting the computer


Now, i got a new pc and to change between the 3 displays, i have to disconnect the one i want to change, and connect the other one


Is there any way to enable such feature on my system?


Specs:
AMD Athlon II 250 3.0GHz
MSI GF615M-P33 (MS-7597)
ATI HD 5670 1GB
4GB DDR2 Ram
WinXP Pro 32Bit SP3It depends on the make & model of the graphics card.  I assume it's a PCI-e X 16, with 3 ports?  VGA, DVI, HDMI.  If that's what you have, you can only use 2 of the 3 at any one time.You didn't seem to understand it fully...

I'm asking if there is any way to have the tree monitors connected and just use a tool to select which ones to use

These are the 2 modes I wanna choose between:
AMITech 62x & HP Flat PANEL Monitor
LG Projector & HP Flat Panel MonitorPerhaps a KVM switch could be used to accomplish this but I'm really just making a guess here.  The way I envision it working is that the HP Flat Panel Monitor would be connected directly to your video card.  Then, the other port on your video card would be connected to a KVM switch which would be connected to both the AMITech 62x and the LG Projector.  I'm going to look around and see if i can find a good KVM switch for DVI then...Wish I'd thought of this before posting my previous reply but here's another suggestion.  Install a second video card so that you can keep all three display devices connected to the computer.  You could just turn off one not being used.  This might be a lower cost solution since KVM switches can be quite pricey.  I presume the second video card would have to a PCI card.  They generally cost more than PCI Express cards but cost less than KVM switches.  QUOTE from: Ryder17z on December 15, 2010, 06:09:29 PM

Q:  How can I run three monitors or more monitors?
A:  To run three monitors you will need at least two nvidia graphics cards. One of the two cards needs to have dual video outputs.* To run 4 monitors both cards would need two video outputs. Add additional cards for each additional monitor. If you run out of PCI-E ports, or are using AGP, PCI cards can be used, althought multiple PCI cards may not function well together and issues may arise. Not all cards can be used in conjunction with one another. Be sure that drivers exist for and offer support for both cards. UV+ and other usb to VGA or USB to DVI adapters can also be used in liu of video cards.
As a regular user of KVM switches i am pretty certain they are intended for the opposite use than was suggested.IE to use LESS monitors not more. As an example a KVM switch allows one monitor/one keyboard/one mouse to service whatever the parameters of the KVM switch is.As FAR as i know 2/4/or 8 computers with one monitor/keyboard/mouse. truenorth Quote from: Computer_Commando on December 16, 2010, 11:24:23 AM

Well, he'll need two graphics cards but they do not need to be nvidia.  He already has an ATI card so getting another ATI card makes sense in this situation.  When you say older pc you was able to run three monitors on tell me how old? Some How I suspect you had a video card that supported two monitors and a on-board motherboard video connection that supported your third connection you used at the time. Which is a different animal then what many reply's suggest...

Your current pc has two connections that are on-board video connection or a inserted video card?    Quote from: multifacetedview on December 17, 2010, 05:36:22 AM

You raise an interesting point.  The original post (see below) is not really clear on exactly how his old computer was configured.  Would be good to have more details on that.

By the way, welcome to the forum.I'm thinking it's never been done...
Without 2 vid cards i cannot see 3 monitors on 1 PC....
But i've been wrong twice this Month   in this case i don't think i am.Well I think the devil is in the vague details. He does not say he could view all three monitors at once but only to select which of the three to run without reboot such as perhaps the 2 monitors on the video card, turn those two off and then turn on the the third one being the one connected to the on-board video card. (I didn't say it made sense wanting to hook it up this way, just saying.) If I remember right some some makers of Pc's yrs ago ALLOWED you limited access to bios control on-board video controls to allow you to disable it while you was operating within OS. Thinking at time it was a VGA on-board. (Dusting the cobwebs off the Grey matter.) lol
 
So my question to you is. Was you able to view all three monitors at once in the old set up?  Or.. more along the line of the above suggested being you could run the two on the card or the the on-board one but not both ?

Yeah, AFAIK, most systems with onboard video will not allow using the onboard port(s) and a card in an expansion slot simultaneously.  In other words, installing card usually either automatically disables the onboard video or the user needs to access BIOS settings and disable onboard video in order to use the add-on video card. (Thanks for the welcome, soybean )



Agreed, I think that what he is running into on the newer system he needs to reboot to access the bios to disable one to run the other, unlike when he did not have to in his older system.

End result if this is how he is applying the original question. (a) NO, there is no way to enable the feature on the newer system.
