I don't see the problem with a ceiling light and a TV.


Consider that people's eyes adjust to the amount of light. Its hard to
see something when a MUCH BRIGHTER thing is nearby (like a ceiling light
in almost the same direction as the TV screen). The same thing can
happen when reading (a bright light BEHIND the book makes the book darker).
