A.4 Video-Timing Method
If all of the previously described methods fail for your configuration,
it is possible to specify the exact timing numbers for a particular
resolution. The last method for setting the console resolution also
uses nvedit. This method is more involved and requires
knowledge of all timing parameters for the desired resolution, and
is only meant for monitors whose resolutions are not available in
the video-mode method. Please refer to Appendix C for detailed
instructions on using nvedit.
NOTE: The video-timing method should be used only if the
previous methods have been unsuccessful.
