@louf said in Which display resolution to use for widescreen TV with A/V output:

Very annoyingly in the raspberry community commenting things out is treated as if it's a valid coding technique.

The Setting is "disable_overscan" which can have one of two options "0" which translates to "False" and "1" which translates to "True"

The settings default is "0" so by commenting it out, it effectively does not read it, and it defaults to "0"

Hope that makes it a bit easier to understand.

You'll need to provide more details about the screen you're trying to use - does it connect via HDMI or GPIO ? What make/model is it ?

@Haemogoblin Check out these topics for some solutions to some similar problems

Can you be more specific ? Video in connections does the older TV support ? SCART/Composite/Component/VGA ?
The simplest solution is to get a composite video cable and use the analog output from the PI to connect to the TV.
