which video controller? i've had similar problems with an nvidia
card and a monitor with tight timings. by beating on aux/vga
and stretching the timings in vgadb, i did get something my monitor
can sync to, though not a proper resolution.

I tried it with different monitors and they work with higher
resolutions so it must be something with the monitor.
Unfortunately I have little knowledge of plan9 and vgadb.
Can you tell me how you did that?

i'm ashamed to admit, it was by trial and error.
and a few hacks to vga/nvidia.c.

I think it must be possible without hacks.
I'm probably just too ignorant to get it to work :/

this depends on your monitor and your exact nv chip.
i have a syncmaster 204b and a
1.0.0: vid 03.00.00 10de/01d3 10 0:fd000000 16777216 1:f000000c 134217728 2:00000000 16 3:fc000004 16777216 4:00000000 16
this chip doesn't work at all without some modifications,
which are likely always correct. but the timing is still off;
the monitor doesn't sync when the chip is given the
correct timings. i don't have an oscilliscope handy, so
i don't know if the timing is correct and the monitor
can't handle it or what. and i don't remember which
changes have to do with timing anymore.

i attached my hacked-up copy. nv almost always goes off
into the weeds if given a bad timing. so you might
not want to do this on your fileserver.

i'd probablly start with some of the register fixups; i'd
try not to mess with the clock unless i had to.
