It shouldn't need to extend, cloning should work just fine, and in
many ways that makes things easier because whatever you are doing on
the laptop would match what is on the TV, but in an appropriate
resolution. Extending to or from another monitor makes sense because
it gives you more screen real estate but extending to a TV just makes
your laptop screen useless assuming the TV is the primary display
which is what you are after because you don't want to be moving
things over from the laptop screen to the TV, you just want to the TV
to be your Display.
This is more about the video card then anything else. Typically any
video player playing will be outputted to the TV automatically and
appear perfectly because that is what the manufacturer designs the TV
output to do properly, but to get a desktop view is not so easy. ATI
cards work pretty well in outputting and it is easy to make size
adjustments. Matrox use to make the best most easy to use, and I
guess they still sell an external USB box for this purpose. I have a
ACER HD laptop with a Intel GM45 card that works neither well nor easy.
The 16 inch laptop uses a Mobile Intel® GM45 Express Chipset with the
newest driver and specs are
16" HD 1366 x 768 = laptop
16:9 aspect ratio
16" Full HD 1920 x 1080 = HD video and or TV
If I set it to clone the laptop is at recommended 1366 x 768 and the
58 inch PlasmaTV is at recommended 1920X1028 but no matter what
adjustment I make the Taskbar, and the Title bar on the TV are cut
off vertically and some of the horizontal = start button is as well.
For some reason the vertical and horizontal are just a little too
much and that makes opening and shutting down programs a guesswork or
keyboard task.
None of the Panasonic picture formats make it better and the
Intel adjustments don't seem to help at all probably because it is
outputting at the correct 1920 x 1080 so it is not letting me adjust
smaller.I could live with it except my Meida Center view is cut off
at the perimeter and that makes things annoyingly awkward.

Ah...I see now...extending means that both montors are your desktop,
and both run at their own resolution, but can be used independently,
in a sense. You can just drag the video to the projector (second
display) and run it full screen (maximize to full 1920x1080 on
projector, but not on the laptop). So the movie plays on the
projector and the laptops screen will show whatever is on that
desktop part of the desktop. Just don't have a window lapping
across the two displays or it will show on the projected image.
Think of your desktop being made of two rectangular areas of pixels
like 1024x768 (on the left) and then 1920x1080 (on the right). When
you drag a window say from left to right, it moves across from the
1024x768 group of pixels into the 1920x1080 group of pixels.
The Windows is smart enough to know that each group of pixels is
actually a monitor, so you get the option of running full screen
windows in either group of pixels, in addition to stretching windows
across both groups. It gets wonky when the two rectangular areas
have different vertical dimensions, though. I do this all the time
for presentations, but not really for movies.

Yeah, you don't want cloning. I do the same thing with my
projector and Acer laptop, and I need to extend if I want full
1080p on the projector.
