THE BEST TRICK IS TO HAVE THE LARGEST MONITOR THAT YOU CAN GET AND THEN TO SET THE "RESOLUTION" DOWN TO THE LOWEST VALUE (WHICH IS TYPICALLY 640X480) THIS WILL MAKE EVERYTHING AS LARGE AS POSSIBLE WITHOUT ACTUALLY HAVING TO MUCK AROUND WITH ANYTHING ELSE.
TO GET THINGS EVEN BIGGER YOU CAN THEN GO AND ADJUST YOUR PROGRAM PREFERENCES AND LOOK FOR SOMETHING LABELLED "FONT" AND THIS WILL ALLOW YOU TO SET YOUR FONT SIZE TO A BIG NUMBER.
ANOTHER TRICK IF YOU CAN'T MAKE THAT WORK IS TO TAKE A MESSAGE FROM MAIL OR YOUR WEB BROWSER, SELECT ALL OF THE TEXT AND COPY-PASTE IT INTO AN EDITOR WINDOW. THEN YOU CAN MAKE THE FONT AS BIG AS YOU NEED.
I DON'T KNOW WHAT KIND OF COMPUTER YOU HAVE OR WHICH PROGRAMS YOU ARE RUNNING SO I CAN'T GIVE REALLY SPECIFIC STEP-BY-STEP INSTRUCTIONS. IF YOU WRITE BACK WE CAN HELP YOU OUT THAT WAY. EVEN BETTER IS IF YOU CAN FIND SOME REASONABLY COMPUTER-KNOWLEDGEABLE FRIEND WHO CAN HELP YOU OUT IN PERSON. THERE IS A BIG CHICKEN-AND-EGG PROBLEM HERE WHERE YOU CAN'T SEE THE CONFIGURATION SETTINGS UNTIL AFTER YOU ACTUALLY GET THEM CONFIGURED!
GOOD LUCK!
