Most monitors have a menu button that allows you to adjust settings and 
the like.  It may be that Fedora has set to something that is just not 
optimal for.

Check your monitor model number through Google and see what the true 
resolution for the monitor is and set the resolution to that value.  You 
could be set to some setting that does not adjust well to the actual 
resolution of the monitor.  (For example, my laptop is 1920x1200.  If I 
set it below that it looks weird.)

You also might find the display panel and set it for "Generic LCD monitor" 
with the proper resolution for your display.  It is possible that X is 
giving it bogus information thinking it is a tube type monitor.

Truth is stranger than fiction because fiction has to make sense.
