Multi Monitor Setup Questions

post #1 of 7
Thread Starter 
I've been thinking about getting a three monitor setup for my next rig and I've thought up a few questions I need answering.

Since most cards come with 2 DVI and 1 HDMI, will there be any loss having to convert one HDMI output to DVI?
How would multi card setups work?
If I had 2 cards and plugged all outputs into one card, would the other card still help?
Would those cards need to be in SLI/Crossfire? What if they weren't?
What if I had 2 monitors on one card, 1 monitor on the other?
Will I likely need 2 cards to play high res, highly graphic intensive games at like 45fps+? (3 monitors? 3 times the work?)

HDMI and DVI are both digital.
0 Loss in quality, though DVI doesn't carry audio.

Multi card setups work good. Depending on your goals, you might just be able to enable onboard graphics alongside the dedicated GPU for a 3rd monitor. Just beware anything put on the monitor plugged into the onboard will be tons slower than the stuff on the GPU plugged ones, so it's not ideal for triple monitor gaming but works fine for multi tasking.


3 Monitors of equal resolution is 3x the pixels, but isn't exactly 3x the work.

so I can just use 2 dvis on the card and an hdmi -> dvi and have 3 dvi monitors without any problem?

so since that means I can get all 3 monitors on one card, how that work if I wanted to add an extra card for some extra futureproofing? Would I just put them in crossfire/sli to get them to work together? Or would I do 2 into 1 card and 1 into the other or something crazy like that?

It depends on the card, sometimes cards come with 3 outputs but can only use two at a time. They add the extra output plugs for compatibility and convenience.

You really have to check with your specific card for more info. What the model of it?

It would likely be more beneficial to run the cards alone, not in SLI/Crossfire if you're looking for multi-tasking but if you want to game across all three, SLI/Crossfire is the way to go.

When in SLI, VRAM capacity is not added.
When alone, VRAM is on a per-card basis.

Why would I need to mess with the display port? Couldn't I just have 2 DVI -> Monitor and then HDMI -> DVI adapter -> Monitor and leave the DP connector alone?

can't do that unless the video card is exactly like the Sapphire Flex (which as a active adapter built in) or any Geforce 600/700 series, need to use the DP I/O with a active adapter to get Eyefinity in general to work.


at least there are options out there in terms of video cards if needed on either side.
