We don't have tvs, only a portable dvd player for long car trips or when she needs to stay awake for an event.
Bedrooms are for sleeping. Anything else attachs an expectation of activity and fun to that room, and it's harder for them to sleep when you need them to.
All DD has in her room is her pet cage, bed, bedside table with a lamp and clothes dressers.
There's a seperate toy room for the activity items.
