Ok, so while I am running a TH2G at the moment, I am tempted to convert to the dark side and buy a 5850.

I am somewhat worried about all the fuss and dissatisfaction from previous TH2G owners. I have a couple of questions that I have searched for answers for and have not been able to find, sometimes due to one person saying one thing and then another posting that they can't do the same thing.

Advantages
No expensive middle box
Great video card performance over equivalent-price Nvidia card

Disadvantages
Still need at least one active DVI - DP adapter
No bezel management but I assume driver updates will correct this eventually
No option of a fourth monitor from a secondary output <-- this is the killer downer for the flight sims I build.
Eyefinity users on the whole still seem very unhappy?

1. Can I run a resolution of 3 x 1680 x 1050? If so, does it support 59-60Hz or not? I have 57Hz compliant monitors anyway but for future proofing.

2. Can it run at a 16:9 aspect ratio monitor native resolution, ie 3 x 1920 x 1080, also for future proofing?

3. How easy is it to set up for games (ie Oblivion, FSX, GRID, Left 4 Dead)? For example, I find the Matrox SGU really good.

I am very tempted. Very, very tempted. The small voice in my head still has doubts... help me silence them?

At the moment all we are only seeing from ATI are the 5770 and 5870 series card on the market. I suggest you look in to the up coming 5870 (SIX) series cards that will be able to connect 6 monitors on one card. I think this card will do the trick for you.

The card is the 3rd card down on the left. See the connectors on the back they are mini-display ports. ATI is also working on their own connectors that will go Mini-Display-to-DVI for this card.


Also take a look at this early video review of the Eyefinity technology.

If watching this video and it doesn't do it for you then give me a few days as I'm waiting for my card to arrive and I can tell you first hand.

HTH :wink:

Disadvantages

yes for TripleHead

No bezel management but I assume driver updates will correct this eventually

yes it should

No option of a fourth monitor from a secondary output

yes on the current 5870 card. however the future 5870 "Six" will be able to do what you want since it'll have more than 1 DP port and so support up to 6 screens total, however for a 4 screens setup you'll need 2 DP Panels or 2 active adapters. (or 1 of each of course ;) )

1. Can I run a resolution of 3 x 1680 x 1050? If so, does it support 59-60Hz or not?

there no such limits on eyefinity, you can run as high as each output supports, 3 x 2560x1600 is possible & 120Hz monitors should also be an option

2. Can it run at a 16:9 aspect ratio monitor native resolution, ie 3 x 1920 x 1080, also for future proofing?

yes why couldn't it do that? just need 48:9 aspect ratio in games ...

Thanks for all the answers. The 5870 (six) looks interesting. <-- when does this come out?

For cost reasons, can I:

Install a 5850 in the primary PCI-e slot and run 3 monitors (for say out-the-window visual scene for FSX)
Install a lesser ATI card in the secondary PCI-e slot to run a fourth monitor for instruments only?

Or will that ruin the able to run Eyefinity?

After reading the post that JKeefe wrote which was a summery of the information in the EyeFinity Discussions thread it is clear that...well read on.

[quote]Example, having 2x 5850's in Crossfire, have a SLS 3 monitor setup, and have 2 of the monitors connected to the DVI ports of the primary card, and the 3rd connected to a DVI port on the secondary card. If this feature was enabled, it would save alot of hassle and money in having to buy an active adaptor, which then could be spend on a 2nd ATI card for better performance, (CrossFire 5850's > 1x5870 + active adaptor)

To do this type of setup you'd need a genlock/framelock type connector that is typically a workstation feature. Without this it would make the timing/syncing of the panels between card particularly difficult and you'd be getting "panel" tearing.

Excuse me for not visiting the forums very much since Monday as I am recovering from major surgery.

MS operating systems recognize two graphics cards uniquely, which is to say that one card can operate in EF SLS mode, and the other in traditional modes. So the scenario of having something like a 5850 drive three displays in SLS mode and another graphics card (such as an evil green card) doing something else should work. I say should work because I haven't actually tried it myself.

For those who persist in saying an active DP to DVI adapter is required, I have to persist in saying "no, that is only true if you have more than two DVI monitors or are trying to match two existing DVI monitors with a third DVI monitor." There are people like me who are buying three monitors purely for doing EF. I know of a number of folks selling their Apple 30" displays to buy three Dell U2410s. And some folks are buying a third monitor that is DP capable.

Please be complete in your comments - anything less is erroneous. Active adapters are a configuration choice, not a requirement.

I'm not sure that answers my question, because the three panels displaying the 'one' image are all coming out of the same card, and an entirely separate window / panel / image is coming out of the second card.

The way I read it, the comment you posted relates to having one part of the original three coming out of the second card.

Ie the way I read it:

My question
First card - three panels - one group or virtual monitor
Second card - one panel - second group / monitor

Your quote
First card - 2 panels, forming 2/3 of one group or virtual monitor
Second card - 1 panel, forming remaining 1/3 of group

Happy to be corrected if I am intepreting it wrong.

I feel like you understand what I am asking, and that's about the same assumption I had made.

I am going to use a second ATI card to keep it in the family, no point being half red half green like some cheap plastic christmas ornament.

Well, in my case, I am modding an existing system that does not use DisplayPort monitors, so in my case it is a requirement when calculating cost of changing.

Here are the facts that I know to help clear things up.

> Currently No Crossfire in Eyefinity SLS mode, if you use 2 cards in crossfire you will only be using 1 of the cards the other wont be doing anything.

> You can not split the displays between two cardss for Eyefinity all the monitors must be connected to the same physical video card.

(FYI the demo of the flight sim running on multiple cards was multiple instances of that game each running only a section of the game)

> You can use 4 monitors with the current card, but only 3 of them at the same time, and one of them must be the display port connection.

> Bezel management is supposed to be on the way but never bet on what is to come only what is here.

> Crossfire support for eyefinity is also supposed to be in the works though sounds like the ETA for this is not nearly as close as the bezel management.

MS operating systems recognize two graphics cards uniquely, which is to say that one card can operate in EF SLS mode, and the other in traditional modes.

Yeah will work as long as you can get it working on the driver level.

I had a 4850 Crossfire Setup and when I got my 5870 I could not run the 5870 and 4850 at the same time using the 5870 drivers. I had to use the standard Catylist drivers for both cards to function at the same time, and that meant no 5870 functions like eyefinity.

These early 5870 drivers are ONLY working for 5000 series cards, they are not backwards compatible with older ATI cards, and if thats the case I would imagine it even harder to get a nvidia card working along side of it. Or it maybe easier as the ATI drivers wont install for the Nvidia card so it can just use stock windows drivers, nothing fancy but it will work for the purpose of more displays.

All of these 'parameters' will work for my proposed setup.

...and if thats the case I would imagine it even harder to get a nvidia card working along side of it. Or it maybe easier as the ATI drivers wont install for the Nvidia card so it can just use stock windows drivers, nothing fancy but it will work for the purpose of more displays...

Good point. It might be easier to use an Nvidia card as the secondary card to avoid driver conflicts.

Guess there is one way to know for sure...
