Triple 1440p advice

[SimonMaltby]

I'm looking to go triple screen and not quite sure how to go about it.

I'm running a pair of MSI 780 Lightnings in SLI and have a single Asus PB278Q 27" 1440p monitor.

I also already have 3 Asus VN247H 24" 1080p monitors that I use for work.

I know I can connect up the 1080p monitors using the HDMI, DVI-D and DVD-I from one of the graphics cards, so using the 3 1080p monitors should be easy.

But what if I wanted to get another couple of 1440p screens, how would I connect those to the GPU's for triple 1440p?

I spend all my time in Driving Simulation games like iRacing and rFactor so I'm not pushing the graphics too hard.

Do you recon its worth going tri-1440p or should I go for the cheaper tri-1080p?
And if I do go tri-1440p how would I connect them?

Thanks for your advise.

When running SLI surround you have to have your monitors connected across both cards. If you wanted to run 1440p then two monitors on card 1 connected via DVI-D and one on card 2 connected via DVI-D would be the way to go. Indeed I would recommend using the same connections if you want to run your 1080p monitors (it's what I do). You can run a 3(surround)+1(accessary) display setup. Not sure I recall seeing anyone using a 1440p screen for the accessary screen so not 100% if this would work.

Edit: Just checked on the configurator: http://www.geforce.com/hardware/technology/3dvision-surround/system-requirements and it looks as though you would be OK connecting the 1440p display to the display port output on card 1 if running the three 1080p displays in surround.

Thanks for the link Stephen... that makes it clearer.

So Looks like I could use the Display ports from cards 1 and 2 and then run from the DVD-D on the first card for the 3rd screen.

I guess I would need a DVI-D to Display Port adapter to run the 3rd screen at 1400p therefore giving me 7680x1440?

3x 1440p would be quite immersive!

No reason not to use DVI-D on all three monitors, will save you having to use any adaptors. You can connect as you suggest but when I did something similar for my 1080p screens I found that I had a different colour space on the one that was connected by DVI-D, there is a fix in software for this but I didn't investigate any further and just connected them all via DVI-D instead. Useful for me anyway as the display port input on my screens (Asus VE278Q) had some oddities in the way it operated.
