I have a 19 inch Hitachi (HM-4119). It is 48 khz horizontal and 60-70
vertical, just for giggles.
Here is my "monitor" section of XF86Config...
Section "Monitor"
Identifier "Hitachi Monitor"
VendorName "Hitachi"
ModelName "HM-4119"
# Bandwidth is in MHz unless units are specified
Bandwidth 100.0
HorizSync 48-52
VertRefresh 58-64 # typical for a single frequency fixed-sync monitor
Mode "1056x796"
DotClock 64.98
HTimings 1056 1160 1272 1312
VTimings 796 800 812 846
Flags "-vsync" "-hsync"
EndMode
Section "Screen"
Driver "svga"
Device "Cirrus 5422"
Monitor "Hitachi Monitor"
Subsection "Display"
Depth 8
Modes "1056x796"
ViewPort 0 0
Virtual 1180 850
EndSubsection
EndSection
Notice that the flags "-vsync" and "-hsync" are necessary with my
Hitachi to make the sync pulses go in the proper direction, which is
negative-going with my monitor, whereas a garden-variety VGA is
positive-going.
I also have to use an old 13 inch Mono monitor to see what is happening
when the machine is booting.
Why wouldn't it be possible to modify the console driver so that the scan
rates could be changed on it to allow those of us with large, fixed-scan
monitors to see boot messages and use the virtual consoles? I'm gonna go
look to see where the video card is initialized.
