To few resolution options E7440 and E7240
We have multiple E7x40 model ultra books in use and we have the problem that when docked, the resolution is not good. The image is too big for the monitors.
We use A E-port port replicator and one or 2 Dell Monitors. The standard resolutions are : 1920x1080, 1280x1024, 1024x768 abnd 800x600.
What we did find is that if you run c:\windows\system32\custommodeapp.exe you can add custom resolutions, but this means we have to do this manually for all the ultra books we are going to deploy....
Also we found that our old Eizo 15 - 17 "monitors are not able to show these high resolutions, the max resolution is 1024 x 768 and on 22" Dell monitors we have to put the text size on 100%
update: I have installed the latest BIOS (A07) with no luck. Also tried the graphics driver from the Intel site, but that driver is not valid. (you need to use the manufacturers driver.)
We have found a workaround, by manually installing the intel driver (newer version than the Dell driver) the problem is solved an you have more resolutions to choose from
is there another way (driver , bios update) to fix this issue?
UPDATE : The latest drivers fix this issue.
Thanks All

Hi All, the latest drivers from the Dell site (the support section) solve this issue.

I'm having the same issue. 1920 resolution is just a little too high for the built-in display, and things get ugly when I crank up the text size. My old Dell (E6410) had a 1440 resolution that was perfect, but the 7440 drops right down to 1280. Very frustrating.
I tried installing the latest Intel driver but it errors out at the end of the install. I have the latest driver available from Dell.
I actually haven't even tried plugging into an external monitor yet, so that's next. :/
Would love help too!!

You have to install the driver using the "have disk" option. In that way you can install drivers working around the "you need the manufacturers driver" popup

Correction! I had just clicked "update driver" and for some reason the system thought it was up to date. When I went in through Computer => Properties => Device Manager, and then went in with "have disk" and selected the actual folder with the Windows 8 64-bit driver, it updated and now gives me 13 resolution options!! AWESOME!
Thank you!!

Thank you for the reply... Tried that, but unfortunately it didn't work. I still have the same options? Any ideas?

Sadly it doesnt seem to work for win 7 x64. Installed Intel driver, didnt change anything. Dell needs to fix this.

Can I use our 2560x1600 screens on the E7240 + E dock?
