Hello. Long story short, I've been trying to fix something on AmogOS (a riced RaspPiOS) on my Raspberry Pi 400. The overscan issue. Apparently the Pi 4 and 400 don't really do with 1366x768 display. Especially with my Walmart-brand 10" TV. I already the Foundation's forums, but they haven't responded yet.
To put it simply, I just want to get rid of the black bars surrounding my desktop.
Thanks and best regards,
Chase
