Using a DisplayPort cable directly between the E-port and the monitor makes the new Display Driver (NVidia 313.96 Beta) detect the Monitor correctly in it's native resolution 2560x1440@60Hz.
This did not work with an older driver, nor did it work with a DisplayPort<->DVI-D cable.
Now starts the hunt for a KVM that supports DisplayPort...
The dock and switch should be removed from the troubleshooting. Test the laptop and monitor directly via VGA to VGA and then HDMI to HDMI. See if the screen still blanks.
There is no DVI-output on the Laptop it self, only on the docking station.
I've already tried bypassing the KVM-switch to no avail.
Using a DisplayPort->DVI-D cable gave the same results.
I can only get the max resolution using DVI-D port on the dock connect either through the KVM or directly to the Monitor, but then I get these intermittent blankings.
Using a VGA cable connection will only give me up to 2048x1536 according the specs [1]
There were no problems running on lower resolutions e.g. 1920x1080.
I do not think the culprit is the monitor. But you are welcome to contact Dell in your country and initiate a monitor exchange. Let me know if the replacement monitor acts the same way.
Dont think the Monitor is faulty, it works flawlessly with my other Windows 7 computer aswell as my Linux box, both displaying full resolution 2560x1440@60Hz (even in Color!), so I'm not going to ask for any monitor exchange.
I have tried with another E-Port i.e. the one that I'm using at work, as well using a another AC-adapter that outputs 6.7A. Results were the same, or even worse.
Even tried to install the latest beta driver 313.96 beta driver, but when creating the custom resolution and testing, the picture was dizzy (neither crispy nor clear) so it was un-usable.
I'm quite confident that this is display driver issue and the problem is probably some timing info mismatch between the driver and the Monitor. I'm hoping you ask the right people to look into this to have this problem resolved.
I would be happy to try out another driver with enhanced timing data, if you would get one in your hands.
