W710/Z710 External Screen

Hi all,

I have a W710 and i would like to invert the color of the external screen.

When in power saving mode (Automatic mode) and the external screen powers down it goes black.
When turning the screen on (Always On mode) the screen will be black with white text as long as the backlight is on. When the light switches off, the screen will invert the bgcolor to white and text to black.

If i'm not mistaken, the screen uses power to turn the pixels white (LCD with inverted polarisation filter) and thus powering nearly 90% of all pixels continuously - which i find pretty dumb in regard of the standby time. However i prefer to be able to see the time or any missed messages without having to activate the phone.

I'm also guessing this will be the same for the Z710...

Any ideas?

just to be clear: when the screen gets no power its black...
