1st class!

This has really worked on the 23" LED BenQ that I've got hanging over my bed. It's very bright and used to make my eyes tired after I switched out the overhead lights. Now, when I switch off the lights, it softens down with a slight rose tinge while everything remains perfectly clear. I didn't even bother to set it up properly.

Highly recommended! I might even read all night. Thanks for the post.
