Just set your Amiga 1200 at its default screen resolution of 640 X 200. Octomed will run at this resolution and look great on the color composite output. Better yet, shitcan Octomed and run Soundtracker, Noisetracker, or Protracker. They look much nicer then Octomed and are perfect for 640 X 200 res.
BTW, I use monitors like these on my Video Toaster 2000 setup. They work very well as the preview and program monitors. They are light weight and do not take up much space on my desk.
