I'm sure there must be a simple answer to this, but I can't find it...it comes in two parts
1) How can I tell how many colours (and/or the screen resolution) the current display is set to.
2) How can I programatically change it.
A part of the program I've written displays JPEGs and it would be useful to post a warning message to say that under the current number of colours the JPEGs may appear low quality etc etc and to give the option to switch up to a mode that shows more colours...you get the idea :-)
Thanks in advance,
