I did some research and found this:



"I've worked out the problem and it's the cable.


Apparently cheapo cables have pin 20 connected which they're not supposed to under the display port standard and this causes the issue.


More info here http://en.community.dell.com/support.../19813562.aspx


There's actually a NEC notice about it http://www.necdisplay.com/cms/docume...ort_Notice.pdf


I've got two cables and pin 20 is connected and I'm sure your three cables will be the same.


I've just ordered the bellin displayport cable from the Dell site which is a certified display port cable and doesnt have pin 20 connected.


I'll report back once I receive it."

and this:



"The Belkin cable finally arrived (delays due to stock availability/flooding hampering delivery here in Brisbane), tested with a multimeter and pin 20 isn't connected hooray!!! Pluged the cable in, booted the computer with no problems, setup eyefinity and now happily widescreen gaming at 5760 x 1080.


So Far:


Good = Belkin & Link Depot


Bad = Astrotek


If you're experiencing problems check for continuity between Pin 20 on each end of the cable with an Ohmeter/Multimeter, pin 20 is the pin closest to the bevel on the displayport connector (IT SHOULD NOT BE CONNECTED)."

I still have a problem I can't find Mini DisplayPort to DisplayPort or HDMI to DisplayPort cables from Belkin or Link Depot.
