Latitude E6420 Video Resolution
I have an E6420 with Integrated graphics and 1600 X 900 screen. It sits on an Edock port replicator. I am trying to find out what the max resolution is from either the DVI or Displayport of the dock and the HDMI port of the laptop. I cannot find the specs anywhere. I have downloaded every manual I can find. Can anyone help me? I want to connect a 27", 2550 X 1440 monitor to the dock. HELP PLEASE!

I have a refinement to this question.
I have just obtained my Dell E6420, previously I was using a Dell D6xxx.... with..... a high quality CRT external monitor that is capable of 1600 x 1200 at 85 Hz.... but I was using it as 1280 x 1074 @ 75 Hz
i want to do the same thing with my E6420 ... BUT... although it offers
75 hz (and 60 Hz)
at 1074 x 768
and 1600 x 1200,
it only offers 60 Hz at 1280 x 1074... this is nuts!
How can i find the missing mode i need?
Thanks
