RE: To few resolution options E7440 and E7240
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!!
