Scorpio,
I tube TV times, it was suggested by the video Gurus that a backlight be placed behind the video monitor to ease eyestrain. There was a specific color, or temperature of light recommended, but I don't recall what it was. It seems like that is what you are considering.
In our main TV room, we have small ceiling can lights bath the wall behind the TV. In the bedroom, we have no back lighting and it sometimes causes my eyes to water.
Why not give it a try-it can't hurt.
