What does the test modes do?

When you go to the advance settings theres the sd audio and video test and the hd audio and video test. What do they do?

The video/audio test presents a test pattern and a tone. The tone is the same annoying tone on the signal strenth meter.

It is used to adjust your TV

Does it adjust by itself or do we have to adjust it.

You would have to adjust your TV. It's nice they added the test patterns, but would have been even nicer if it was like a THX DVD that walks you through the adjustments so that you know what you are supposed to be looking for.

When I can find the time I'll try to create something that will help with making adjustments.
