They are that shape for a reason.
They are setup in a 16:9 Screen Ratio; this is the standard for high-definition television. That is what gives it the WIDEscreen.

So, the smaller the size of the LCD, the more chance you probably have in getting one that is more square/4:3.
This is because of our eyes as they have the capability to see a wide distance in the horizontal plain but they can't see a wide distance in vertical plain, that's why The new TV's are said to be Wide Screen with 16:9 ratio.
