Default what cards can drive multiple 2560x1600 screens?

A former classmate, now working for an oil company, boasted that they
have a workstation with 3 monitors - nothing new there.
But he said each monitor is 2560x1600.
So I presume this system has two cards. And since DVI can only spew out
1920x1200 (unless you choke the refresh rate), these must be using
DisplayPort. Is there a card with dual displayports that can pump out
8 megapixels worth of screen?

Plenty. Some hints:

- Look into Dual Link DVI
- Check out the latest high-end cards of NVIDIA in both the GeForce as
well as the Quadro range.

You could probably realize the mentioned 3 displays using a single card.

Patrick.

Since this came up recently:

1) ATI high end card with six ports on the faceplate.
ATI Eyefinity allows up to six monitors. And typically, you
might have to use DisplayPort for four of those. In other words,
two ports are "full flavor" of dual head (multiple options), while
the four others are only DisplayPort.

This one is all DisplayPort (six of them).

http://www.newegg.com/Product/Produc...82E16814129262

Mixed bag. Should run three monitors for you, somehow. Has two DVI dual-link
conventional dual head, plus two DisplayPort and one HDMI, for max 5 monitors.

http://www.newegg.com/Product/Produc...82E16814150665

ATI includes a table, for converting DisplayPort, to other standards.
When they list 4096x2160, it isn't likely 60Hz refresh. They can
cheat by doing 30Hz (useless). You have to use some care, when reading
resolution specs, due to the cheaters out there. Who wants to game at
30Hz ? They should really include a refresh number too.

http://support.amd.com/us/eyefinity/...y-dongles.aspx

2) A single NVidia card is dual head (as are many cards from the last
12 to 15 years). So you can drive two monitors. And a dual link DVI
can do 2560x1600 (see DVI article on Wikipedia). Maybe a recent version
of HDMI can do that too. DisplayPort right now, I think that sets the
record for pixels.

With the single NVidia card, you can drive two monitors.

http://en.wikipedia.org/wiki/Dvi

"Example display modes (dual link):

WQXGA (2,560 × 1,600) @ 60 Hz with CVT-RB blanking (2 × 135 MHz)
(30-inch Apple, Dell, Gateway..."

So dual head times dual-link DVI would be two 2560x1600 @ 60Hz monitors.

3) With NVidia surround, you use two cards in SLI, and you can run
up to three displays off that. Don't really know the details of
what driver does that. Or what other card configs (triple SLI, quad SLI)
might be possible. There is a web page (configuration checker),
that gives more details.

http://www.nvidia.com/object/3d-visi...echnology.html

(Configuration checker)
http://www.geforce.com/hardware/tech...m-requirements

Sample output for a GTX480 pair.

"3D Surround Configuration Tool

Geforce GTX 480, 2-way SLI, 3D Surround, Landscape

GeForce GTX 480 2-way SLI With 3D Surround (Landscape)

Maximum Resolution: 5760x1080
Maximum Resolution (Bezel Correction): 7680x1080
Maximum number of displays: 3 in Surround and any number
supported by additional cards"

While there are also hardware devices for splitting a single
port output, into two monitors, that won't achieve any extra
pixels.

On the latest 3840x2160 display, the back of the unit uses two HDMI
in span mode, or it uses one DisplayPort, which tells you which
connector standard is more capable. Asus apparently doesn't build
this monitor from scratch, and it's rebranded. Might have their own
firmware in it, you never know. So if you absolutely needed to buy
one, it is available as Sharp PN-K321.

"ASUS PQ321Q Black 31.5 inch, 3840 x 2160 $3500.00"

Just saw this and thought I'd pass it on.

http://www.theinquirer.net/inquirer/...radeon-hd-7970

"Initially Microsoft tried to run the 11520x2160 resolution setup using
a single Radeon HD 7970 card but according to the firm the performance,
unsurprisingly given the resolution, was found wanting. Microsoft then
set up a three-way Crossfire configuration of Radeon HD 7970 cards and
claimed that with high settings save for shadow details and particles
it managed an impressive 62 to 67FPS."

So there are crazy people out there.
People with unlimited budgets :-)

Well, not exactly. Monitors were on loan. Those are the $3500 or more
a piece monitors.

"several Sharp PN-K321 4K Ultra HD displays that
I had on loan for a short period of time"

Ball cap is extra. Maybe it was on loan as well.
