Big Buck Bunny at 60fps on a 31kHz Monitor

Priya Sandoval 24-07-2026 12 Comments

DESCRIPTION

The 60fps release of Big Buck Bunny is a good test for motion on a VGA monitor, which draws each frame in a single pass without interlacing.

The result is smooth motion with no smearing, exactly what CRT fans keep telling people about.

What to watch for

  • Motion clarity when the bunny runs.
  • Whether the tube keeps up with 60 distinct frames.
  • Colour accuracy in the green meadow.

    Nice work. For anyone reading: the service manual is on page 14 of the archive scans.

    Any chance of a parts list? I would love to follow along with the same kit.

    We had one of these in the school library. Nobody was allowed to touch it.

    Posting this to our club channel, a few of us have been stuck on the same fault.

    The tip about the grounding strap should be in bold at the top.

    This takes me straight back to Saturday mornings at my cousin’s house.

      Six-month check is on the calendar.

    My local repair cafe has a whole shelf of these waiting for volunteers.

    Did you check the ripple on the 5V rail before and after? Curious how much it moved.

      Good question. We measured it and it dropped by about half after the recap.

    Honestly the composite version has a charm the RGB one lacks. Fight me.
