Solved Overscan question

[Zetabyte]

Hi - upon first boot of Recalbox my menu screen was shifted to the right. I compensated by turning on overscan and editing the config.txt file and rebooting. That worked fine. My Recalbox menu is centered but now when I start a game the game screen is shifted to the left by the same amount.

How do I set overscan so that both the Recalbox menu and the game itself are both centered?

Thank you.

I solved it. My TV is 720p so instead of forcing 1080p mode I set this in config.txt to set it to 720p:

hdmi_group=1
hdmi_mode=4
