How could TV be better?

I think that the TV could be better  :

If we can see all the thing as they are in the same size as they are in the reality.
Or it can be only the screen without the frame. 
Or in 3D without classes .
Maby you can chose the effect you want for example: thermal , X-ray ...
I think I can be excellent if we can make world documents , power point and exel...
Or you can take pictures and make videos.
If I can be in the place of the actor  will be an amazing option .
I can choses any film in the world in any time.
Maby I can talk and say which film I want r which Chanel I want so it comes when I say the name.
