Anybody know if there is single-GPU 3-monitor support without displayport or FLEX?

I will resort to FLEX or an adapter if absolutely necessary, but I would rather get a 28nm card if it supports 3 monitors without the need for a displayport adapter. Anybody have info on Kepler or the HD7000 Radeons? I don't game much anymore but would like three monitors for multitasking. Right now I am only using 2 out of my 3 monitors (the third is on loan to my gf who asked to borrow it practically the moment it landed at our doorstep), but I'm going to want that monitor back someday.

If you want a card that supports 3+ monitors nativly then here you go

http://www.kfa2.com/MDTGTX560.shtml

If you want a 7XXX or kepler card that can do it then wait until they release....

Yea... 50Hz. Those kfa2 cards are mostly gimicks that don't work well at all. Remember the previous generation only had 1600x900 max for 3 displays.
So what's wrong with flex other than that they are more expensive than a regular card + adapter? And what are your graphics needs?

Don't expect any of the next generation cards to support 3 TDMS (DVI/HDMI) devices; it's an added cost that benefits very few users. The solution is always going to involve an active DP->DVI/HDMI adaptor.

If you use 3 DP monitors instead of relying on the DVI ports will the tearing go away?

theoretically yes, dp has its own bus timing and doesnt rely on tmds signal generation. going with 3 dp monitors also helps in keeping idle voltages down as the blanking cycles are not dependent on tmds intervals.

for 3+ monitors setups, buying a native dp monitor is always the easiest solution (certainly far fewer headaches) and saves you from buying any adapters.

I see your point but he asked for a GPU that supported 3 monitors and I gave him a link to one.

Also please explain what the previous generation of cards has to do with this one? That GPU is advertised as supporting up to 5760 x 1080 and as he specifically says he doesn't game much 50hz really shouldn't be much of a bother.

Asus hd6950/70 CuII. There's also a Powercolor 6870 2Gig eyefinity-six model You say "someday" though. Unless "someday" is "someday soon" though when you do get your monitor back those models won't available.

I don't want to buy old technology, I want 28nm power efficiency.

Eh, I suspect mini-DP will become the standard, but I am not sure, so I am trying to avoid buying a DP->DVI/HDMI adapter until the dust settles on that front.

My monitors don't do DP. :)

You could wait for a dual GPU keppler. All the dual GPU nVidia cards can run 3+ monitors native DVI.

KFA cards aren't perfect. Last generation (based on 460) had resolution limitation of 1600x900 and current gen (based on 560) has limitation of 50Hz. Given those limitations, I'd be surprised if there aren't other quirks/bugs.

Anyway, cheapest route would be a flex card (don't know about tearing issue with them) or a workstation card since you don't need graphics power.

There's the MultiView series that have 4 DVI outs:
http://en.wikipedia.org/wiki/Compar...nits#FireMV.2FFirePro_.28Multi-View.29_series
They are expensive new but they are relatively cheap used on ebay. One seller lists trouble with support (drivers for >2 displays in Win 7) for the 2400 PCI (PCIe version appears to have driver on AMD's website) so best research the driver support before getting one of them.
