This is a "generic" answer to your enquiry. Your video adaptor may have different characteristics.
I suspect that your video drivers are setting the output to provide a specification that ALL display devices can accept.
By default, your laptop has a 16:9 display - and probably has a maximum refresh rate of 60 Hz. However, when you connect a 4:3 auxiliary monitor, plug & play will detects the monitor and configure the video output to a setting that both monitors can accept. Furthermore, you will not be able to set the refresh rate to 75 Hz, if either monitor is limited to 60 Hz.
Without testing, I can't be certain what would happen, if you connected an auxiliary monitor with a 16:9 display. However, I suspect both devices would display the 16:9 aspect ratio. The same principle would probably apply, if you connect a 16:9 HDTV. If not, you would probably be able to configure the output manually (via Control Panel / Video Settings).
I have the reverse situation with my HP laptop, which has a 4:3 screen. If I connect it to my HDTV, the TV display will also display the output in 4:3 aspect ratio, with black bands at either side. However, if I turn off the laptop display and use the TV as the default monitor, the aspect ratio increases to 16:9.
To obtain a more specific answer, it would be helpful to have details of your video adaptor.
If your computer uses an Intel Graphics Media Accelerator Driver for Mobile, the latest versions of this driver allow you to create pre-set video configurations (or "schemes") to meet your personal requirements. For instance, I have created the following "schemes" on my laptop:
1. Laptop only. 4:3 ratio. 32 bit. 1024 x 768. 60Hz. Auxiliary output disabled
2. Laptop and TV. 4:3 ratio. 32 bit. 1024 x 768. 60Hz. Auxiliary output enabled
3. TV only. 16:9 ratio. 32 bit. 1360 x 768. 60Hz. Laptop display disabled

I have a Dell Inspiron E1405 laptop running Win XP with wide screen
(16:9 aspect ratio) dispaly. When I connect to an auxilliary monitor
via a VGA cable the useable area of the display shrinks to 4:3,
leaving unused stripes at both edges. This is fine if the auxilliary
monitpor has a 4:3 ratio. However, I'd like to connect to a wide
screen device (HDTV in my case) and use the entire area of the
screen. Is there any way to do that?
