Netbook VGA output problem

I am using HP's Netbook with Intel Atom processor.

When I connect it to my Sony LCD wth VGA cable, I cant get a full screen display on my LCD. I have tried tweaking with the display settings and changing resolution but that has not helped.

Please advice.

Details? Model numbers?

What resolution are you trying to display?

Have you updated the graphics drivers?

Are you trying to mirror or use the TV as a secondary display?

As a rule, that happens when you run both screens in duplicate mode, as opposed to an extended desktop which would give you access to adjust the resolution of each one independently.
There is an option on the resolution page (don't know if you have XP or 7) that will allow for the extended option and you can also choose which of the two will be the actual desktop, with the bottom taskbar, etc.
If you don't know exactly what I mean, tell us which OS you are using, so as to be able to give you specific instructions.

I am guessing he is using mirroring mode and the limiting factor is the netbooks low res display. If he uses the TV as a second monitor he will beable to drive it at a higher res.
