Thanks for replying. I don't see where to find
the EDID info in the log. I do see this:
(**) NVIDIA(0): Validated modes for display device DFP-0:
(**) NVIDIA(0): Default mode "1600x1200": 162.0 MHz, 75.0 kHz, 60.0 Hz
(II) NVIDIA(0): Setting mode "1600x1200"
which I though suggested that it was intending
to use 75k and 60.
It is a Viewsonic vx2000. Seems picky about the
60 hz vertical.
BTW - I forgot to mention one observation that
I though interesting. When the machine is
powered on I immediately get the out of range
(74.3k, 59.0) message from the monitor. When
X is started, the signal goes off momentarily (it
is doing something) and then the same message
comes back on the monitor. That sounds like
it is not setting the rates at all -- which
have been wrong since power on.
I've tried both settings of UseEdidFreqs.
