Would 20" + 24" + 20" work for Eyefinity ?

Just bought the 5870 last week, looking to go triple screen gaming to mainly play WoW. I do have the Apple 30" Display, but that is not meant for triple screen gaming, besides adding 2 more 30", no thanks way out of my price range.

I do have a 24" Samsung of 1920x1200res on my 2nd computer, how would adding two Dell 2007FP's of 1600x1200res match up on either side of the Samsung 24" ?

Would be the same as 2 of these; http://accessories.us.dell.com/sna/products/Displays/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=320-4687
and 1 of these http://accessories.us.dell.com/sna/products/Monitors/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=320-6272

Would those three combined line up well across Eyefinity ? The dot pitch or pixel count would look uniform between the 24" and 20" ? Thank you

They need to be all the same resolution for triple screen EyeFinity.

Currently the only option for running non-identical displays is SoftTripleHead.

Really ? I know they all have to be in Landscape mode or Portrait mode, no mix and match, but I thought different resolutions could be mixed together as long as the vertical height resolution is the same. For this all three would be 1200 height res, that still would not work ?

Perhaps I misunderstood the details. You could ask one of those members who have a working EyeFinity setup... :)

So any official word on whether AMD will allow a mix and match of Portrait and Landscape modes soon ? I just do not understand why they wouldn't allow the same vertical height across three displays to be allowed in the drivers ?

20" in Portrait + 30" in Landscape + 20" in Portrait, that would give total 4960x1600 resolution, and all three monitors would have the exact same height res. You would use two 1600x1200res 20" monitors but flipped upright in Portrait mode, and one 2560x1600res 30" monitor in Landscape.

I'd better chase a definitive answer on my situation. I have a 24" 16:9 centre and 2 x 22" 16:10 sides. Is this simply not going to work with Eyefinity? I was hoping to run them at 1680x1050 even though that's not the native nres of the 24". It looks ok using SoftTH. Have I just wasted AU$196 on an active adapter?

well you still get the power house of the 5850/5870

For now, SoftTH is the only option for this configuration.

Oh dear. That's a shame. The limitations are turning out to be a disapointment after the initial excitement of thinking this was going to be a solution to the nuisance of using SoftTH.

If you have at present only one 24" 1920x1200 display, just get another 2 x 24" (1920x1200), just make sure at least one has a DP port.

2 x 20" 1600x1200 will not look right, as it is or different pixel-pitch (0.27 vs 0.255), even if you can run them using SoftTH style.

as BHawthorne said "For now" ...

keep in mind EyeFinity is a new technology for ATI driver team ...
Was SoftTH awesome from the first day it went public ?
Did Matrox have all current options on the first day with the first TH device ?

I know its months ago but I would like to throw my 2 cents in:

Afaik Eyefinity only works with 3x the same resolutions - same as Matrox TH2Go. You may use 20/24/20, as I do at the moment, only via SoftTH. Looks like this:

5120x1200:

2 x 20" 1600x1200 will not look right, as it is or different pixel-pitch (0.27 vs 0.255), even if you can run them using SoftTH style.

Right but it will fit well with 20/30/20 - this is what my current goal for next spring is:

But becaus of Eyefinity and a potentially coming new Matrox with resolution up to 3x1920x1200 I´m also thinking about 3x27" triplehead - same power rquirements as 3x24 but huge display. :shock: Dunno what to do...

What I really would like to see is a proper support of 20/30/20 with Eyefinity and/or Matrox TH2GO - you will have 1600 pixels in height which is a much better trade in than having more horizontal pixels with 3x24" or 3x27".

EyeFinity currently runs all screens at the same resolution and orientation.

That is the only hard limitation.

The monitors don't have to be the same brand, or the same model, or the same size. It's perfectly fine to mix and match whatever you like, so long as all of your screens support one resolution in common.

E.g. 30" 2560x1600 + 24" 1920x1200 + 17" 1280x1024 will run as a 3 x 1280x1024 array (3840x1024).

Asthetically, this would be horrendous, but there's no technical reason why it can't be done.

On the flip side, the current implementation of EyeFinity cannot stitch together different resolutions into a single large surface.

e.g. 1600x1200 + 1920x1200 + 1600x1200 will NOT create a 5120x1200 surface in the current implementation of EyeFinity. You could probably get it to run as 3 x 1600x1200 (4800x1200), but the center screen would look pretty weird.

Just for testing purposes, I've been using a 24" center and 19" sides, all running 1680x1050.

The overall effect is, surprisingly, quite convincing. Not enough to dissuade me from my eventual goal of 3x32" LCD running 720p - but damn good.
