Connecting a Third Monitor


Recommended Posts

Hey guys, I have the XFX GeForce 7800GT as my video card. It only has 2 output display plugs at the back. Right now I have a Samsung monitor and my Sony HDTV connected to them. I'm planning to get 2 ASUS monitors for my desktop. But when I get them, how do I connect my HDTV again? The 2 ASUS monitors will occupy the 2 plugs at the back of my video card, so where do I plug my HDTV? Thanks

I 'm confused. You have 1 video card with 2 DVI outputs and you want to connect 3 monitors to it? If i'm correct, you can't do that.

I'm not saying I want to plug all 3 into that video card.. I'm just saying that's what I have. So I want to know what I have to do or what I need to purchase so that I can plug another monitor(HDTV) into my computer.

@nub DVI splitters will allow to plug in all 3 monitors?

Yea another board member recommended that to me. But I don't want another box taking up space. I'm thinking about the Splitter or getting another video card at the moment.

What video card do you guys think will work well with my XFX GeForce 7800GT 256MB. By the way, since I'm getting another video card I might as well get something that will allow me to watch 1080p movies smoothly. Right now my card can only play 720p smoothly. 1080p is really choppy for me.

Thanks.

a new card, or just SLI?

With a splitter you your monitor and tv would share an one output. They would be cloned.

Ohh... I definitely don't want it to be cloned.. so I guess my only option is to get another video card.

I'm still a bit confused about what Kaboose said. I can just buy the SLI and I can connect another monitor?

To run 1080p movies smoothly, you will need the lastest/fastest computer with powerful videocard(s) and probably more powerful power supply if needed. You don't need 1080p for movies on computer. You can watch movies on your DVD player via your HDTV that can run 1080p no problem.

Check your computer for empty slots and see what slot type is available for your video card such as PCI or PCI express... so you will buy the right video card for that slot.

That's a pretty cool setup man.. similar to what I'm going for, minus one of the monitors on the desktop.

So I checked my motherboard and I'm pretty sure it's the PCI express slot. I found a picture of it here: http://www.tbreak.com/reviews/fullimage.php?image=9185

Since I'm hooking up my HDTV to my computer I don't use my DVD player. All my movies are on my computer. Also I would like to watch some vids on Youtube in 1080p.

What's the requirement for 1080p anyways? My video card has 256MB, so if I get another one that's like 1GB wouldn't that help?

Anyways, what PCI-express video card do you think will work well with my card?

Thanks guys

you will need 2 identical video cards for 3 monitors hooked up to your pc.

it might be hard to find a new 7800 or even used.

it might be time to upgrade your whole pc.

It has to be identical??

I already told you what you need.

Having said that though, apparently if you do get a second of the same video card and run them NON-SLI, then you can use the nvidia software to make use of one of the outputs on the second card. If you wanted SLI, then you would need 3 of the same video card, a motherboard supporting 3 way SLI, a 3 way SLI bridge, and a pretty beefy power supply. Of you could go for the dual head 2 go or triple head 2 go devices (which work VERY well) and is probably the cheapest solution.

If you're ruling out a splitter (which I agree with), you have 2 major options. The best choice is to go buy another 7800GT and run SLI. It'll increase your performance along with letting you have up to 4 monitors. If you dont have a free PCI-E slot or cant run SLI for some reason, your other option is to buy a PCI video card. You can use any card that uses the same drivers as your 7800GT, it does not have to be the same video card itself. Doing it this way will NOT increase performance though, so it would be a much wiser choice to get a matched card and do SLI, but it really comes down to what slots you have available.

Incorrect. You can just get any PCI card to drive the 3rd monitor, but ideally you will want the same brand (NVidia/ATI) so it uses the same driver.

nope getting a non identical video card you will have to choose video output of one or the other.

believe me i have 2 non identical video cards in my system currently, and putting the video in the lower version one produces no video, though it detects the monitor.

ati cards are a little different though. but for nvidia they have to be the same model.

Ohh... I definitely don't want it to be cloned.. so I guess my only option is to get another video card.

I'm still a bit confused about what Kaboose said. I can just buy the SLI and I can connect another monitor?

by that i meant, 2 identical cards in SLI or getting a new single gfx upgrade?

If you put it into SLI mode, it disables the slave card's video out ports. No need to even be worried about SLI.

Thanks.

The pic you showed me, that is ram slots... I am talking about the slots where your current video card is at. You can put another card and place it under your current video card.

Understand what I am saying?

How much ram you have? I am not talking out that comes from your video card. If you have 1 gb ram or less, then you might need to upgrade to about 4gb or higher ram so it might work that you can run 1080p movies smoothly... see if it helps.

You don't have to get the identical, you can get same brand or different brand... mine has different brands on it... no plm.

I have no idea how much you pay for... it's up to you to get a video card of your choice depends on how much you want to pay for and what you use it for... Like I said before, if you want to run 1080p movies, you will need to upgrade some parts or whole system.

Wow a lot of different answers here. So I'm guessing I need an identical card in order to run 3 monitors?

Also Mr Candyman said I need 3 identical cards to run SLI, but homeboy rocketshoulders said I only need 2 to run SLI. So is it 2 or 3?

But anyways whats the big difference between running SLI and not running SLI?

Thanks

    • Not even an OLED display on the laptops. Also it seems that the laptop design isn't the same as the Surface Ultra model. Looks like bargain bin at high prices.
    • VirtualBox 7.2.10 by Razvan Serea VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. Presently, VirtualBox runs on Windows, Linux, macOS, and Solaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, 7, 8, Windows 10 and Windows 11), DOS/Windows 3.x, Linux (2.4, 2.6, 3.x, 4.x, 5.x and 6.x), Solaris and OpenSolaris, OS/2, OpenBSD, NetBSD and FreeBSD. Some of the features of VirtualBox are: Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox. Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.

    • OK, now ask yourself how are they going to enforce that law? By requiring every single adult to prove their age and provide their legal identity documents to an UNREGULATED 3rd party company that already has a long track record of multiple data breaches. Not to mention, parliament have voted AGAINST this ban, twice, and Starmer is going ahead anyway. So, where's the democracy here, because that looks like dictatorship to me. The solution here is parental responsibility, not government control. Run some public service announcements on TV and UK social media teaching parents how to setup parental controls. That's already been proven to actually work. But the, this is not and has NEVER been about keeping kids safe. It's about control and monitoring. Watching what you're doing online and controlling what you can see and what you can say.
    • Interesting read. I knew the adware was quite controversial at the time, however never realised to the point The Guardian wrote an article about Patchou. I just said no and enjoyed his creation, I’d probably be a lot more wary of something like that today though.
