Public bug reported: I work with an ASUS Zenbook UX31A and put it on the Dell monitor U2711. The Zenbook has HDMI output.
While the monitor supports 2560x1600 there is always just max 1920x1080 selectable due to wrong EDID-informations (I am not entirely sure about the cause anymore). That wasn't a (big) problem for me, until now, while the ubuntu wiki describes how to add undetected resolutions ( https://wiki.ubuntu.com/X/Config/Resolution#Adding_undetected_resolutions ). When I attached the Dell monitor I just executed a shell script which adds the modes as described in the wiki. Now I updated to Ubuntu 14.04 LTS which changed the game: When I start Unity, I have to launch an application first otherwise the resolution falls back down to 1920. When I have the 2560-resolution and I open the ubuntu settings, the resolution falls back again. When I start the image viewer (eog), the resolution falls back again. This is really annoying and it would be great if there would be a solution.
