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? |

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. Regards, Patrick. |

Is there a card with dual displayports that can pump out 8 megapixels worth of screen? 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" http://www.newegg.com/Product/Produc...82E16824236338 http://www.amazon.com/Sharp-PNK321-3...=Sharp+PN-K321 Paul |

Is there a card with dual displayports that can pump out 8 megapixels worth of screen? 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. http://blogs.windows.com/windows/b/e...er-second.aspx "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. http://blogs.windows.com/cfs-file.as...436903D0.j pg Paul |
