Ah no.  Sorry hehe. 
 
I don't even look at the laptop screen this "effect" is on my monitor. 
 
Imagine you're watching Spiderman at full screen on a 1280x1024 display.  The video proportionately 
looks like it has been stretched to that size. 
 
However, there is a frame that LOOKS like it is 1024x768 in size, surrounded by black covering the 
movie.  So you can only see 1024x768 pixels of this movie at a time. 
 
If I move my mouse to the bottom right hand corner of my 1280x1024 desktop, I can see the 
"bottom right 1024x768 corner" of the movie output.  Let me try some lame ascii art example here:

So imagine that is my screen at 1280x1024.  If I play a movie and stretch it to full screen and my 
mouse cursor happens to be top left of my desktop: 
 
*************************************** 
*                           |                               * 
*                           |                               * 
*                           |                               * 
*                           |                               * 
*-----------------------                               * 
*                                                           * 
*                                                           *

The box I have added represents how much of the movie I can see.  If I move my mouse around 
inside that box the box doesn't move.  However if my mouse cursor "pushes" any one of the box's 
edges, the box moves in that direction.  So if I moved my mouse to the right, that box will move to 
the right, revealing hidden movie elements but hiding parts of the movie off to the left (because the 
box moved to the right).  Confused yet? lol I know I am. 
 
I suppose it is like putting a picture into a picture frame that fits, but then putting a sheet of 
cardboard over the picture with a hole cut into it that is smaller than the picture.  To see different 
parts of the picture you'd need to move the cardboard around. 
 
I reiterate though, this is not the laptop display panel.  This is an external monitor with the drivers set 
to output the hardware overlay onto the external display.
