What Kind of shelves?

I have decided on shelves because I don't want to sit the TVs on a plinth or a table but what kind of shelves?

-Four separate shelves, one for each TV?
-One long shelf, will have less room to play around with layout than four separate shelves, plus will nned to be a lot more heavy duty to hold all four
- White shelves? To dissapear into the wall? Probably the best option, in my critique they said I was "over doing the retro aesthetic", so plain white shelves will solve this problem
