I have an Elitebook 2540p with a docking station running Windows 7. I purchased an Asus VE276Q specifically because it supports DisplayPort as that is the only high capacity video connector on the docking station.
When I boot up the Elitebook, I see the "Starting Windows" graphic on the monitor via Displayport, but then the screen goes black and says "No Signal" once Windows starts, nothing I do will display the Windows desktop on the Asus monitor.
If I switch to a VGA cable, everything works as expected, but the font quality is poor as VGA can't drive such a large monitor with acceptable quality.
What do I need to do to get the DisplayPort connector to work when Windows 7 is running?

Well, it's been a month and a half since your post, so I'm guessing you have it resolved by now, but in the off-chance you don't, I suggest a right-click on the Desktop and select Graphics Properties... Then click Multiple Displays and it's pretty straightforward after that. I just joined the forum and searched for DisplayPort issues, which is how I bumped into your post. Regards, Joe

I'm having the same problem. No signal out the display port on my Elitebook 2540p. I've tried display port to HDMI dongle. I've tried a display port male to HDMI male cable and nothing. Hitting FN+F4 did nothing. I also tried using the display port on the docking station and nothing. If I use a VGA cable I can run dual monitors. Is there some secret to activating the display port? I looked all through CMOS and couldn't find any toggle option there. It shouldn't be this difficult! Help please.
