ATI eyefinity (3 monitors) how to?

[intel]

Hi guys

I wanted to have a single video card for my three monitors, so I purchased a MSI ATI Radeon HD 5770 http://www.frys.com/product/6139339?site=sr:SEARCH:MAIN_RSLT_PG

On the website it said

- Support up to 3 monitor outputs simultaneously and independently.(one of the outputs must be DisplayPort.)

I bought a displayport adapter from Monoprice DisplayPort to DVI adapter http://www.monoprice.com/products/p...=10428&cs_id=1042801&p_id=4827&seq=1&format=2

However, my setup won't work. The card only allows me to output to two monitors and the third monitor is not seen by Windows.

Neither of my monitors are DisplayPort capable (samsung models from early 2010) and I thought the adapter would do the trick. Any tips, ideas?

Thanks

I believe you need an active DP adapter to convert DP to DVI.

Here's a good resource if you want more general eyefinity knowledge

Thanks. I did buy a passive DP to DVI from Monoprice but it did not work. 1920x1200

Any cheap ACTIVE adapter suggestion? Thanks

Saphire and Powercolor both make active adapters for about 30$

acctually, that adapter from monoprice isnt ATI certified, so it wont work.

in my experience this one works and is certified by ati.

fixed that for ya.

Sapphire, PowerColor and XFX active DP to DVI Adapters I know work.

And keep in mind, if the mDP /DP to DVI doesn't say it's active it will not work.

FYI, I believe that you also need Vista or Win 7 to even run three monitors, definitely to run eyefinity. I had a 5750 that wouldn't drive 3 monitors under XP even though all connections were native (2x DVI 1x DP).

This is also correct.

They require WDDM based operating systems to create the Single Large Surface.

This is a single link, is there such thing as a dual link?

 

[Ludic]

Yes, dual link is only required for resolutions over 1920x1200 however.

you don't need active adapters for 1920x1200. i would know, I've used them.

I run 3x dell u2410s and use passive adapters and it worked. (2x dvi to mini dp and 1x dp to mini dp)

Because you have a native DP in the chain of three.
