if you can not get the extend my desk top to keep the check mark in the box
this is were your problem lies
hoster is not the problem !!!
the problem is in your set up in the video card set up
you will need to find out what is wrong there before hoster is going to work like it should
go to the web site or call the people who made your laptop and have them trouble shout the video problem there once you get that fixed hoster will run as it was made to do

we can tell you things all day but the people who made the unit
should be able to walk you thur it in a snap
and if it is a dell like you said ask them right off the bat if the video card in side your unit will support extend my desk top mode some cards wont
