Panasonic widescreen telly odd geometry....?

04-08-2004
My Panasonic 28PM1 displays a slightly horizontally-stretched widescreen picture but 4:3 seems fine. Are all widescreen pictures not 100% accurate but slightly stretched sideways to better fill the screen? Can I decrease the width in the service menu of just the 16:9 picture without adjusting the 4:3 size? Any advice anyone please? Thanks!

If you're talking about a widescreen picture from an analogue TV signal then you will have to stretch the 4:3 picture to fill the 16:9 screen as they only transmit a 4:3 picture (normally a 14:9 picture within the 4:3 picture). Most sets have some sort of intelligent stretching which leaves the centre relatively untouched and stretches the edges of the picture.

I might be a bit out of date now as I no longer repair TVs but all earlier Panasonic widrescreens had one geometry setting for ALL modes ( bad design I thought)

So when you enter the service mode, the TV is in the 16/9 wide mode (Full screen anamorphic) so all adjustments had to be done in that mode.

So too bad if you needed to tweak someting in the 14/9 mode!
