First (just as with monitors) start by carefully choosing a good one.  
Unlike shops in Tokoyo, which have a pitch black room full of  
functional projectors foe users to compare, testing projectors before  
buying in the US may be limited to checking out ones that people you  
know happen to own.

Beyond that, adjusting the hardware controls to an optimal state is  
handy, but in digital mode there tends to be little you can adjust.

Next would come the projection situation. Pitch black, with no  
competing lights or bright objects, to produce good blacks, good  
shadow detail, good gradients, and to make sure the projector "owns"  
your eyes white balance.

After that it's a matter of profiling the projector, being sure that  
profile and it's LUTs are in use, and showing precorrected images  
using a color managed application. This does NOT include PowerPoint.
