-

i engineer on apollo moon program , retirement hobby has been giving presentations grade-school children.  using full acrobat, created pdf use visual aids.  schools use adobe reader display pdf.  there 1 weird problem has popped occasionally.  unfortunately, discover when i'm begin presentation kids have no time troubleshooting.

 

most schools use "smart boards" , problem not occur there.  schools connect computer projector , that's problem occasionally happens.  looking @ computer screen, (all images perfect).  however, projected images stretched horizontally.  can @ both simultaneously , computer screen while projected image distorted!  circular apollo-11 shoulder patch appears oval, persons appear fat, etc., etc.  yes, distortion shows pages in pdf.  happens windows computers.  in fact, in 1 instance, teacher swapped windows laptop macbook (with same projector) , projected images looked good.

 

any clues here, guys?  please type understand - i'm illiterate regarding windows.  computers i've ever owned have been apple, starting apple-ii , graduating mac.

apparently guys clueless am.  i don't feel bad now!
