Hello. The screen looks grey from the front but it's an anti-reflection technology. Seen from below it is white.

No the screen is mounted with the frame because the frame allows to hang the springs to stretch the screen. On the other hand it is possible not to put the black border (visible external frame around the screen) if that is the question.

The black frame protects the stretched fabric and has small black plastic covers for the corners.
The Elite Screen signature is engraved on the bottom bar.

You'll need to put it on, but when you're fixing the frame, you'll need to hold it only by the black frame, which is held in place by simple springs.
