It's model number KDL-32EX403;
It's connected to a sky box and DVD and video players; and
I think it affects all but only sure about the TV as match scores and names only partly appear.
It's been like for a long time but to busy to bother with till now.
Yes Shahid it does give the different screen sizes but it still loses information at the sides (e.g. even on 4:3 setting). Q: not sure how to adjust when on zoom position if it does adjust at all, as the name suggests?
Got it! And did it all from the sky remote. It does not have the button you describe but I used the services button/system set up/picture settings/picture format and changed it from 4:3 to 4.3L.
P.S. 16:9 is a better format as it retains the information and does not lose picture size! I will give you a positive rating in my final response - thanks
