Which display resolution to use for widescreen TV with A/V output

[LouF]

I have RetroPie operating via composite A/V output on a widescreen 720p TV. The RasPi-Config display resolution is set for 1280x720 (16:9). Is this the setting I should use? The Emulation Station screen looks a little stretched compared to when I was running it with HDMI.

(I went to the A/V setup since I don't have enough HDMI ports for everything, and I would rather use the TV's input selector rather than using an additional 2x HDMI switch for the last HDMI port.)

Thanks

Yes that should be fine, try playing with the overscan settings, if it does what you say it does.

@crush Excellent.

I ended up using:

overscan_left=30
overscan_right=30
overscan_top=-12
overscan_bottom=-12

with

#disable_overscan=0

This commented-out line is as-is is additional information - the explanation in https://retropie.org.uk/docs/Overscan/ is a little contradicting to me and has many double-negatives, but I went with "try to avoid disable_overscan=1". Ignoring that and understanding "disable overscan" as it reads lead me to believe I wanted overscan enabled but adjusted - it seems uncommenting this would work the same. My head is spinning, but now circles are not ellipses, squares are not rectangles, and the screen is filled.

Thank you!

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.
