Re: "Video frequency too high"

I ran a google search for "Nvidia fixed aspect ratio timing" and got a few
hits in forums discussing problems with the setting. The blog below
describes a workaround using Powerstrip to create a custom display profile
for the monitor with the aspect ratio he wanted to use:

Just now wondering if you do have monitor drivers (IPO generic MS monitor
profile) installed for both displays. Should in theory allow you to prevent
non-supported display settings from being selectable in the display driver.

Does neither monitor show the horizontal frequency on its OSD? For example
mine shows VF=60.09Hz, HF=64Khz and Pixel clock =108.03 Mhz. I tried a few
different desktop settings, 1280x720, 720x576 etc. but none of the
frequencies reported in OSD changed. Monitor specs should indicate which
frequencies are within range and what the vertical refresh should be at
certain resolutions.

Ok, I've swapped the screens, so: Eizo at VGA and Hyundai at DVI. Now, if
I use the "fixed aspect ratio" mode for the Eizo, the screen does not go
black. It also doesn't show an error. Well, the Hyundai at the same output
showed an error. But, I can also not say that it works with the Eizo
because the aspect ratio is still not fixed. Instead, it is like before
(5:4 instead of 4:3 (still talking about the 1024x786 resolution)).
Nothing changed.

If I now open the Eizo's OSD and have the input settings displayed, it
says 1024x768@60Hz. Well, that's ok. My conclusion is that this is also
the setting if the Hyundai was connected to the VGA output, but then I
don't understand why this setting makes the Hyundai go black and show an
error. It's still 60Hz and it should still work.

Unfortunatelly, both screens don't have an aspect ratio setting built-in.

But, I'm a liar.... in that way that the newer driver version does not
even have a configuration option for the aspect ratio for the VGA output.
It is only there for the DVI output (where the Hyundai is currently
connected), and this setting worked and works. Maybe the option for the
VGA output has been removed because it didn't work in previous versions -
as I have experienced now. So, not the end of the world, I can live with
it.

Thx,

greetings, Horst

Screen refresh rate shouldn't change when you change aspect ratio
so why it should be different when you select something like fixed
aspect ratio seems a bit strange. Is the setting valid on non-DVI
connections?

The connection in question is the non-DVI (D-Sub/VGA) connection.
The setting can also be made for the DVI connection. There it works.

The fixed aspect ratio setting seems to be most often
used with wide-screen displays to correct the aspect ratio for 4:3
aspect games etc.. Might not even be the vertical sync that is
changing, it could be the horizontal sync that is going out of
range with that setting. Corrupt driver install maybe?

I've always cleanly uninstalled a previous driver version before
installing the new one, as instructed. As I reinstalled the whole
system only few month ago, I'm not going to setup everything again
because it always takes me pretty long to make the system run like
before. Anyways, I'm pretty sure it is not a driver installation
problem. By the way, the problem is the same with the recent driver
version.

Possibly the
problem is with that particular monitor. Can you switch the
monitor connections?

No, because the screen currently connected to DVI (the Eizo) is also
connected to another PC by it's analog connector. Because the other
PC has only analog output, I won't be able to permanently use the
Eizo's VGA input for this PC. But I will temporarily try it and post
the result here.

In any case this isn't actually a Windows XP issue AFAICS, because
it is Nvidia driver specific. There's no such setting in ATI
drivers though the effect may resemble the "use centered timings"
option
(which is not user adjustable).

Yes, but I didn't know where else to ask.

Anyways, thanks, I'll give feedback


Greetings, Horst

Thank you, but reading the tool description, I don't see any
relation to my
question. I don't want to playback Windows media files. I want
to know where
to set the screen refresh rate that is used when I set the
screen's aspect ratio to "fixed aspect ratio".

In the driver's control panel, there is the folder "screen
resolution & refresh rates". There the refresh rate is 60Hz. On
the "nView Display Settings" folder, if I open the "device
adjustments" for the screen, then open the "Display mode
timing" folder, I can select "fixed aspect ratio timing". As
soon as I do this, the screen goes black and says "video
frequency too high". I don't know which frequency is used and
where I can set it. The
only location is the folder mentioned before but there it is
already set correctly.

Hi,

whenever I try to set the "display mode timing" of my screen
to "fixed aspect ratio", my screen tells me "video frequency
too high".

System:
Geforce 6800
+-- TFT D-Sub 17" (Hyundai) @ 1024x768 (60Hz) (1280x1024
native) +-- TFT DVI 17" (Eizo) @ 1024x768 (60Hz)

Driver: nVidia 94.24 (newer versions create problems)

The option works with the DVI connected screen but not with
the one connected to D-Sub (which support 60-75Hz). With the
latter one, I get the
mesage above. The other timing modes ("auto-detect" etc)
work ok.

Where can I set the frequency? Well, I do know where I can,
but it is already set correctly, so I don't know what I
should do in this case.

(no, I can not change the connection of the two screens)

Greetings, Horst
