I am using NX 4.2.25-1 on two stock installs of Ubuntu 14.04, a desktop and a laptop, running KDE 4.13.1.  The laptop (Intel graphics) has a resolution of 1366×768, and appears fine on the desktop (Nvidia graphics), which has a resolution of 1680×1050.  However, when I try to access the desktop from the laptop, NX resets the desktop resolution to 1280×720, and it then becomes impossible to access the whole of the desktop.  Is there any way to force NX to accept the 1680×1050 resolution?  I seem to remember there was a setting for this in versions earlier than 4, but it seems to have disappeared, and although I’ve tried all options of the display buttons I can’t stop it doing this.
