Probem with connecting projector with laptop in vista OS

Hi,

You need to change your graphics card settings from extended desktop to cloned desktop.
You will find that if you use your mouse currently to drag a window or icon across to the projected screen, it will move the window there. This is the extended desktop.
I assume that what you want is to have the exact same screen on your laptop and your projector - this is called the clone screen.
These setting can be by right clicking your desktop, select properties. Click on the display settings tab. click on the advanced settings button, and the the graphics card tab. There should be another button to launch the graphics card settings there.

Hope this helps.

Change the display properties to 800x600 then higher, try, it must work.
