[9fans] Problems with a Digital monitor

[Carlos L.M.]

Hi all,

 I have tried to install Plan9 on a Pentium 120. When
setup starts detects vga card right (S3 Virge). But I
see double images. My monitor is a Digital with this
frequencies:

  HorizSync 48.36
  VertRefresh 60.00

 On the installation disk I have configured like a
Multisync 65 Hz.

  How Can I modify plan9.ini to put it right
frequencies ??

Thank you very much and sorry for my bad english.

You can change the monitor= setting in plan9.ini to try
different pre-configured monitors, but that won't get you
too far, especially if you have exact frequencies you need.

You need to edit a:\vgadb and make yourself a monitor
entry with the timings you want.

is a good explanation of how video timings work.
