Anyone using HD 4870 X2 + triplehead and is it compatible. Thinking of changing my card and HD 4870 X2 is a possible card.

Looking to play Arma2


Thanks

It's possible, but as with all ATi cards, the maximum resolution you will be able to use is 3x1440x900. ATi seem to have no interest in dealing with this issue... which is a shame, as it means that anyone wanting wide-Triplehead at WSXGA+ resolutions needs to use nVidia.

The Matrox forum rep said the new ATI drivers will do 5040x1050, about 2mths ago! Its just no one here seemed to have an ATI card (or monitors) to test it.

Really? Awesome. When I asked ATi about it (about four weeks ago) they had no idea what I was talking about. So I assumed nothing had changed.

So. Ignore me, then.

well suppose going to find out just ordered ati 4890 " black edition " will keep my fingers crossed :)

Id wait till someone confirms its all ok before going ATI though!

EDIT: Screw it, I dug out a Radeon and tested it and made a guide, see:

Hi all,

I wanted to wait to make this announcement until Catalyst 9.7 was officially released, but since I forsee lots of discussion about this, I've decided to let everyone know now.

As of the 9.7 Catalyst build (releasing in July), combined with Matrox's new Powerdesk 2.05 (released yesterday), all of the outstanding ATI bugs should be officially resolved.

This includes:

- Lack of general 5040x1050 resolution for all ATI HD series cards.
- Problem with the "DVI 4" output head not allowing 4320x900 and 5040x1050 mode. (Now both heads of ATI boards will behave the same and will offer all modes properly)
- Fix to enable widemodes with multi-board crossfire configurations
- Fix to enable widemodes with X2 series ATI cards
- and a big final item: increased timing support for 5040x1050 mode with ATI cards to allow 5040x1050@59Hz in all scenarios. (This has been tested with most panels previously found not to sync with nVidia GPUs at 57Hz. Those panels now DO sync correctly at 59Hz).


To enable these fixes, users will simply need to install ATI's 9.7 Catalyst, and then install Matrox's 2.05 Powerdesk:
http://www.matrox.com/graphics/en/support/gxm/software/
the powerstrip method mentioned above should not be necessary. (Cataylst 9.6 also has a few of the fixes already, but not everything. So feel free to use it for trial & error in the meantime at your own discretion).

We will be counting on feedback from you guys to determine if all the fixes are functioning correctly for various scenarios. So we'll be watching your comments carefully.

We should also give thanks to ATI for this support, since I have been working with them for almost a year now to enable these features and they have been very receptive to making the necessary changes. (It just took some time) :)

Happy TripleHead gaming everyone :triplewide

Ha! It's great! Really great because I just wanted to change my 8800GTX to something more powerfull. I nearly decided to buy really expensive nVidia 280, but now with new Catalist drivers I can buy cheaper 4870 or even 4870X2 with better pricehorse power parameter :D

Hi all,

Just a minor update to my previous post:

In addition to the 2.05 Powerdesk and 9.7 Catalyst driver, you will also need to flash your TripleHead2Go firmware to a new version that supports the 59Hz timing.

This will be available for download around the same time that 9.7 releases.

I will keep everyone posted.

This is excellent news!

Im running a 4870x2 and will be trying this as soon as possible.

Do you have any estimates of a release date for the 9.7 build?
