Getting "good" resolutions

Hi,

It’s my first post on this forum, so hello everybody.

I want my application to dynamically change canvas and viewport size depending on window dimension (it’s handled in onresize event handler).
But the problem are set of good (well performed) resolutions (note that mobile devices are also in consideration).
Is there a (programatic) way to get array of such resolutions?

Thanks,

Btw: on 800x600 I’ve got less fpss than on 1024x768
