AFAICS there is nothing, really nothing, in the User Guide (the word "resolution" appears three times, two of those in relation to printing...).

Graham,

The good news is that scaling and resolution independence support are now built in to v. 6.5 and higher, and it's pretty easy to support all sizes and resolutions of mobile screens. The fullScreenMode property is your friend here. There are a couple of good tutorials at livecode.com:

http://lessons.runrev.com/s/lessons/m/15262/l/156477-how-do-i-make-my-app-scale-to-fit-the-screen-on-all-devices

To handle image display at different screen densities there is one more wrinkle you need to implement. See this tutorial:

http://lessons.runrev.com/s/lessons/m/15262/l/156530-how-do-i-support-different-device-screen-densities

This should get you started, and as I said, it's much, much easier than it was before v. 6.5.

Regards,

Devin
