Hi,
Check the resolution you have set. generally Projectors do not support high
resolution. if your projector supports only 800X600 max and if you have set
higher resolution on your laptop this problem can occur. change the
resolution to the one which is supported by both projector and flat screen
monitor and see if it helps.
also provide more infromation on the model of your flat screen and the
projector which will help address your issue if this doesnt address your
issue.
