Sony Bravia Input Labels

Recently purchased a Sony Bravia 40" W series LCD tv and would like to
know how I can turn off the input labels.

When I use the tools menu and change from the TV to watching a dvd
using HDMI1, a label HDMI1 appears white text on a grey background in
the top left hand side off the screen. How can I turn this off?
This occurs with any input source except the TV.

I have been through the manual cover to cover many times and cannot
find how this can be done.

Thanks...

Well my Sony to do what you want to was
-Menu
-Set-up
-Video Lable
-Program

Its in the same area as Captions,Language, and Tilt Correction

Im sorry I just reread your post. My directive was for changing the
label name given to each input.

You're saying the lable stays on all the time?

Do you have a "display" button on your remote that should turn the lable
on/off.

There is no Display button on the remote.
However the top left button toggles various items to show/not show on
the screen and whatever I did last night appears to have fixed the
issue.
The input labels show initially but then disappear after a few
seconds.

Thanks for your response.
