I am running Raspbian on my raspberry pi, and have it plugged in to a vga display via a converter. The display is way to zoomed in, and I wondered how to fix that.

When I run /opt/vc/bin/tvservice -s I see: state 0x12001a [HDMI CEA (1) RGB full 4:31, 640x480 @ 60Hz, progressive

When I run /opt/vc/bin/tvservice -m CEA I see: Group CEA has 1 modes: (prefer) mode 1: 640x480 @60Hz 4:3, clock:25MHz progressive

Thank you!

    "Via a converter" means I have connected it to a VGA display through a HDMI to VGA converter box.
