Other Running Dell U2711 At Full 2560x1440 Resolution

Anyone with the Dell U2711 monitor know how to run this at full resolution?

I have a GTX 680 graphics card which has two DVI ports, one is a DVI-D duel link and the other is a DVI-I duel link.

The Dell U2711 comes with a DVI-D cable, so would I need to purchase another cable in order to run it at full resolution?

Would I need to purchase another DVI-D to DVI-I duel link cable?

I would have thought it will run at full res using the one that comes with the monitor.

 

It will do indeed.

 

I was under the impression the monitor needed two cables to run horizontal and vertical resolution separately?

If this is the case why would Dell put two DVI-D duel link connectors on the monitor? likewise with the GTX680 graphics cards?

 

Because the monitor can accept input from multiple sources, and the GPU can output to multiple displays.

My u27 is set up using a single cable that came with it.

 

Single dvi cable here = 2560 x 1440

 

You mean 1x Dual DVI

You cant output 1440p without it being a dual DVI. (i think thats what you meant, im just clarifying)

 

You got me before I saw it and had a chance to edit! Just to confuse things I meant a single dual dvi cable

 

Use Displayport! You know you want to.

 

As already mentioned you'll only need one dual link DVI cable. It doesn't matter which output on your 680 is used as the dell only accepts digital DVI. You'd still use a digital DVI cable even in the.DVI-I port as you won't need the analogue part of DVI-I.

Alternatively use displayport which will do the same thing but with less confusing terminology lol

 

Your monitor also comes with a DisplayPort cable, You can us that if you want to use 10-bit color support as well (now finding content in 10-bit is a whole new story.. but just saying).

But yes, as everyone mentioned, dual-link DVI is made from 1x DVI plug. Kinda like your graphic card.. it's PCI-E 16x... it doesn't take 16 PCI-E ports.. just 16 times the PCI-E 1x lines. Hence why the PCI-E 2x or 4x plugs on your motherboard are shorter. Well in the case of DVI the plug is the same size, just more pins are used.

 

Dual link DV-I cable here, and that's 2560x1600.

Just use the cable that came with the monitor... you should have no problems.

 

thats good to know then. So the Display port cable supports 10 bit colour? What about DVI-D?

This mine does

 

Technical it can. But the monitor and your graphic card doesn't support it via DVI, and DVI doesn't have the bandwidth at this reaolution to support it in any case.

Please note that 10-bit color support may or may not work for you. While it should, as it's part of the specs of all Geforce GTX 200 series and up, the drivers might not. To know, if it's enabled, you really need PhotoShop CS5, configured for 10-bit color support, and a picture made with such color depth.
