Troubleshooting • Re: Raspberry Pi 5 overscan, CRT component video

Was there ever any resolution to this ?

I have a similar problem with a Raspberry Pi 3B composite output, and a Sony 36in 480i CRT TV.

That would be a VC4 matter... On Raspberry Pi 0-4 you can shrink the image using margin_* properties, in "cmdline.txt" like this:On Raspberry Pi 5 it works differently because there's no hardware scaling (at least, not in the vertical axis) so you have to change the mode-line. The default 704x432i mode is overscan-safe but has generous black borders on each side. A full-scan 720x480i mode is also available. If neither of those meets your needs, you can now declare a "custom mode", for example 720x448i, like this:The rules for allowable video modes are rather complicated and not yet documented.
