Intel HD Graphics 4000 in HP EliteBook 8470p not working with Dell U3014t monitor

[lscr86]

I cannot get the Intel HD Graphics 4000 in the HP EliteBook 8470p notebook to work with the Dell 3014t monitor at a full resolution and refresh rate. I installed the latest HP drivers and the Dell Display Manager, all to no avail.

With a DisplayPort-to-HDMI cable, Windows 7 recognizes the monitor as a Dell Digital Television (?) and the max. resolution is only 1920x1200 @60 Hz.

With a DisplayPort-to-DisplayPort cable, Windows 7 does not recognize the monitor at all, regardless of whether DisplayPort v1.1 or v1.2 is selected on the monitor.

I would like to get the native 2560x1600 resolution @60 Hz via either type of connection. The monitor *does* support that very resolution and refresh rate when connected to an nVidia GTX680 video card in a different PC, so this must be an issue with either the Intel HD Graphics 4000 or HP drivers or limitation of that notebook.

For reference, the notebook does support 2560x1440 @60 Hz when connected via a DP-to-DP cable to a different Dell U2515H monitor. But, this is 1440 not 1600 pixels vertically.

Can anyone help?

Well, your graphics DO support that resolution. But, it could be the monitor itself, or maybe even the cable. Try a different device with that monitor and report back.

As I said, the monitor works with full resolution when connected to an nVidia GTX680 via DP.
