Anyone got eyefinity working with 5040x1050 or 4320x900?

geniv2 · Post by **geniv2** » 06 Oct 2009, 05:03

just wondering..

as my monitors native resolution is 1920x1200 eyefinity seems to force it to 5760x1200.

though all my monitors are able to run at 1680x1050 and 1440x900. I can not get eyefinity on triplehead 1050 or 900

I am uncertain as to how Catalyst control panel handles adding custom resolutions, but have you tried to define a custom resolution for those screens at that then try to enable EyeFinity?

I think I tried that, I set all my independant monitors to 1680x1050 then I went to enable eyefinity it just uses my max resolution of 3x1920x1200

the reason I want 4320x900 is for crysis (amoung other high demanding games). because at 5760x1200 it is 15fps. if I can get it to run at 4320x900 then I can probably get a playable 30fps. (in theory)

Would hope that Eyefinity is not locked to native resolution of the monitors - would assume and hope that you can set the resolution to lower (respecting aspect ratio)

Hopefully this will be addressed in a driver update soon - it seems quite important and high priority to me.

Well the first drivers are still in beta, they havent finished yet so this kinda bug would be expected..

Have you tried turning eyefinity on and using a tool like Atitool or trying to create a custom resolution after?

I was working on building up to triplehead setup, I just finished my main setup (a couple of months ago)

I was targeting TH2Go so I currently have two monitors that support native 1050, i was looking at picking up the TH2Go and a third monitor, but then i saw the release of this card, it has me rethinking the TH2go. I am playing the waiting game, i will not buy (of at least i do not want to) 3 new monitors. I really really hope 3x1050 gets supported.

Waiting to see how things unfold over the holidays.

I do not have an EF card but from what Dave B says it will be OK at 5040 if that is the max res of your monitor it seems that people with 1920 monitors are unable to select 1680x3. This is the impression I have got from a lot of posts.

I run GTA IV in Th2go at 4320x900, even though I could run it at 5040x1050 because it's much more playable at that resolution.

I appreciate what ATI is doing by trying to make triplehead accessible, but they really need to work on some of the features. They're offering a lot of things that Matrox doesn't have and NOT offering all the nice things that Matrox does have. Examples:

EF
+ supports 5760x1200 and 5040x1050 at 60 Hz
+ no need to mess with extra software
- no support for lower than native res
- no support for XP
- no support for CrossFire
- no support for Bezel Management

Th2Go
+ XP
+ SLI and CrossFire
+ Bezel management
- extra software
- limited to 5040x1050 @ 57/59 Hz

ATI have usually gone for quality rather than performance, and running things at native res. even with less AA is just that.

It of course in part depends what display you're using and it's scaling engine but I've always seen a better image at native res. with lower AA than lower res. and higher AA.

The slight gain in performance by res. dropping ain't worth it to me.

That is good to hear, I think ATI has a hit here in EF.

Hi geniv2,

After you have all 3-mons grouped into 1 then go to CCC and from Desktop Properties change your Resoultion from the Desktop area: pulldown.

Not sure if this will work for you, but this where it would be done at.

it works yes and no..

YES - you can change to other triplehead resolution
3840x1024 and 2400x600 but they are 4:3 ratio resolution

NO - I don't see options for 5040x1050,4320x900, 4030x768 or other 16:10 ratio resolutions

Deke · Post by **Deke** » 10 Oct 2009, 06:49

Ya geniv2,

I tried what you want to do and was unable as well, as it appears the native resolution is used for Eyefinity at this time, hopefully that will be changed with other driver updates.

One can only hope.

What about one of those resolution changing programs would that work?

Forgive me for asking a stupid question, as I am new and just wondering.

Thanks,
Deke

I just need to clarify - there is support for non-native resolutions, though we do not offer all perumations dues to the complexities and setup time.

Catalyst will offer 3 modes of Display Group resolution - Native, "Medium" and low (basically a multiple of 800x600, chosen as a compatability option). Medium will change dependant on the other resolutions available to the panel.

There are ideas on how we go about offering more custom resolutions, but these will take time unforunatly.

Yes I knew that part, that you support 3840x1024 I think. But you may as well not even support that. 3840x1024 would look so messed up on my three 16:10 displays, I don't even see the point in using it.

As soon as you start offering bezel management and an option to get lower resolutions (3x1680x1050 and possibly 3x1440x900), I will very seriously consider getting an ATI HD 5xxx card. As you can see, I already have an ATI card, so I am supporting your company, but I think those are two things (the res and bezel) that you should be able to support with a driver update. I don't know how much work is involved in getting those things to work so I won't take a guess. Just like how ATI eventually did give us support for 5040x1050 @ 59 Hz on Matrox (which I am very grateful for), I'm sure that soon they will give us those things that I ask for.

As already mentioned, bezel management is already under development and is the next major feature to be added.
