Version 3.2.x and newer requires a minimum screen and projector resolution 1024x678.

So if you are running a projector for example that can only project 600x800 resolution, then an option if your computer supports two separate video displays, is to use ProSelect's "Mirror Display Area" mode to just show the display area part on the projector. You can find out more about this in our Dual Monitors and Projector Screens article.

You will find lot of good information in this subject on our Projectors and Large Screen TV's page.
