3 Monitors on 1 4000 series card?

[Strawberry]

Assuming I have a DisplayPort, HDMI and DVI monitor, and one of each connector on my 4890, is there any way to use all 3 simultaneously?

I read something about the 4000's only being able to use two. Is it possible to flash the bios / modify the driver's registry to bypass this, since the 5000 series can use as many as you want (sort of like using the registry to allow SuperSampling on 4000 cards).

Or otherwise, is this possible at all? I'll test in a few days once I can.

Edit: Also if this belongs in the Graphics section, please move it there.

AFIAK, all the 4800 series only have two digital outputs and can only drive 2 monitors each.

It would not be possible to flash the cards with a 5000 series BIOS as they are totally different architectures.

Nope. Two out of the three.

But, the card has 3 digital outputs.

Also, I meant flashing the card using the exact same BIOS as it was using already but changing the model number to something else, or similar.

It does? What is the make/model?

Doesn't matter. The GPU itself has two display controllers. The OEMs chuck more connectors on the card to make the output options more flexible.

A lot of laptops are the same. DVI/HDMI/DP + VGA + internal display. Any two can be used at the same time.

Sapphire HD 4890, has a DisplayPort, an HDMI and a DVI output.

Damn, that blows. Guess I will need to saw open my motherboard's PCIe ports after all.

tried this my self tried every thing with no success. So i bought a cheap ati graphics card that wass able to use the same drivers as the 4000's and hay presto 4 monitors. put it in the third pciex16 slot so it didn't interfere with the main cards performance.

Bought a 3850 for £15

I'm wondering about this too I got a gainward 1gb golden sample 4870 and it has 4 outputs: 1 HDMI, 1 DVI, 1 displayport and VGA. http://www.gainward.com/main/vgapro.php?id=86

 

[ard-tullaich]

email the company and see if will run 3 monitors at once

It actually can... but you'll need to buy a triplehead which costs a fair bit?

The short story... buy a new card as triplehead is £100+ if I remember. You could honestly buy something TERRIBLE as your second GPU, unless you're running spanned video or some weird stuff. I know for me it would display firefox with a new feed.. nothing graphical there.

I do like my ellipses today!

 

[MagicBoy]

Fair enough. Triplehead is not listed on the ATI site though...

For what it's worth - it's indeed impossible (Adapter which I foolishly bought before knowing this just arrived and I tested it).

Oh well, cheap+used PCIe graphics card is on its way.
