[Coco] Suggestion if you are working on Under Color proofreading

[Robert Gault]

I should have thought of this some time ago because it seems obvious. 
However, since I did not, perhaps this will help others working on the 
Under Color proofreading.

If you are using a flat panel display, change to native resolution 
before working on the project. The improvement in reading the scans is 
significant.
