What is the recommended viewing distance and placement for the Sony TV?

The ideal distance to watch TV is 2 to 5 times its diagonal screen size, and when seated, your eyes should be level with the centre of the screen. When wall mounted, position the TV up to 15 cm away from the wall. You should also position the TV where light does not shine directly on the screen, and keep it away from dust-producing sources such as stoves. (Page 3)
