Default Rates wrong using DVI

I have everything working fine with the vga
connection from my fx 5200 ultra card using
drivers downloaded yesterday (6/8/03).

When I try to connect to the DVI connection,
the log tells me that it is using good values
such a 75Khz and 60hz, but my monitor says
that the actual rates are out of range
(74.3 khz and 59.0 hz).

Here is /proc/driver/nvidia/cards/0

Model: GeForce FX 5200 Ultra
IRQ: 10
Video BIOS: ??.??.??.??.??
Card Type: AGP

I'd be very happy to try to dig out any other
info for anyone who can help debug this.

You don't mention the monitor you are using, but it's most likely a LCD Flatpanel. Those have usually much stricter timing requirements on digital inputs then on the analog inputs. Many will only sync at exactly 60Hz.

You may want to look into the XFree86.0.log file to see if the monitor reported the correct parameters via EDID/DDC. Look especially for a section "Supported additional Video Mode:" which is normally the optimal mode to run the monitor.

The braindead Philips 170B (which I have) reports the capabilities of the analog input on it's DVI-D connector, so autoconfiguration is guaranteed to be always wrong.

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.
