I've had a HD Panasonic Viera TV (not sure what model) for a couple of years now, and it's been great except for one thing. Fore some reason, if the aspect ratio is set to auto, then the picture will try and automatically stretch itself to fill as much of the screen as possible. It can also misbehave. So if I watch an old 4:3 Simpsons episode through it, not only will the aspect ratio be stretched so that everything looks fat, but the scene will suddenly become all tall in a TV scene of the programme because my TV recognises the border of the TV as being dark. I've also got issues when in 16:9 through my Wii like this. For some reason, "auto" seems to mean that the TV will focus on filling the entire screen, regardless of maintaining the original aspect ratio. So it doesn't only stretch 4:3 content so that it fat, but will also make something all tall if there is letterboxing involved. I can fix the issue by manually switching from 16:9 to 4:3 depending on the programme that I am watching, but it does get a bit annoying. The only TVs that I know which do this are my own and my grandparent's, both of which are very similar, despite not being identical, and they are both Panasonic and of a similar age. Do any other brands have such an aspect ratio issue? If so, what are they?
