vga_getmonitortype man page
vga_getmonitortype — returns the monitor type configured
This returns the monitor type configered in /etc/vga/libvga.config. This function is really obsolete, as the result is of not much use to the application vga_getmodeinfo(3) and vga_hasmode(3) do already check the monitor type and there are more flexible ways to specify it too.
The return value is one of:
31.5 KHz (standard VGA): does 640x480 in 60Hz vsync.
35.1 KHz (old SVGA): does 800x600 in 56Hz vsync.
35.5 KHz (low-end SVGA, 8514): does 1024x768 in 43Hz vsync interlaced.
37.9 KHz (SVGA): does 800x600 in 60Hz vsync.
48.3 KHz (SVGA non-interlaced): does 1024x768 in 60Hz vsync, non-interlaced.
56.0 KHz (SVGA high frequency): does 1024x768 in 70Hz vsync.
does 1024x768 in 72Hz vsync or even better.

This manual page was edited by Michael Weller <email@example.com>. The exact source of the referenced function as well as of the original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
