SDTV 16:9 format or 4:3 format?

Question

Hi. I have a really old Zenith TV and for my PS3 under Display settings, it says whether to put it as 4:3 or 16:9. Which one suits best? The Tv's not widescreen and it's just a regular 21 inch squared.

Answer 1

Aspect Raio of 4:3 is recommended as that will not deform your picture. --Rajat

Answer 2

You must use 4x3 aspect ratio, otherwise you'll play everything in anamorphic wide (ppl are too slim)
