Picture not centered (hdmi out to TV)

[rsn8887]

I have three TVs with HDMI in, two of them display the recalbox picture just fine, but the third one does not. The picture is completely off center (see attached photo) with a large black bar on the left.

Is there an advanced configuration option in Recalbox to center the picture somehow. I now the TV works fine with Vita TV, another 720p source, so I am pretty sure it is a bug in the video out in recalbox. Maybe it is using some non-standard resolution?

I am using Recalbox 4.0.0 on Rpi3 (release version).

@rsn8887 I fixed it by login into recalbox via ssh and editing my config.txt file, uncommenting the hdmi_group line as detailed here:
