A kangaroo ponders the meaning of the monitor

The Hitachi SuperScan 812 (CM812U) is my standalone CRT monitor. I use it for all my old desktops.

Features

  • VGA connection
  • Easily supports 1600x1200 @ 85 Hz
  • Protects against bad frequencies with an "INVALID SCAN FREQ." message
  • Protects against bad signals (i.e. I messed up the settings on my DB-15 adapter) with a rapidly blinking light
  • Has the loudest degauss noise in existence

Quirks

  • The image is susceptible to frequent popping at weird resolutions, like when I have my DB-15 adapter set to output at 1152x870. When not at a weird resolution, things are OK.
  • When displaying a low resolution at a low frequency like 640x480 @ 60 Hz, the left and right sides of the image are horizontally squished. Messing with the buttons on the front of the monitor doesn't seem to alleviate this. Thankfully, once I get a proper display resolution working, the problem seems to disappear.
