Help wanted for video driver.

Hi there,

I have an unfortunate combination of a Samsung LCD display (710v) and
an
Asus mainboard with an integrated SiS 661 video adapter.

The display is designed to work at 1280x1024 60Hz and it works
perfectly
on other video cards.

The SiS 661 video card works perfectly at 1280x1024 with other CRT
monitors.

When I try to use them together the maximum resolution available in the
Windows XP settings is 1024x768.

If I erase the SiS driver Windows will start with his default VGA
drivers which allow me to use the display at 1280x1024 but the graphics
are slow.

I tried to download and install several drivers from SiS and Asus and
also to reinstall Windows but I always have the same result. I also
unsuccessfully tried to install different monitor drivers to try to
make
the video card think it's a normal CRT display.

Is there any way to override the driver settings changing values on the
registry?

Thank you in advance for your help,


Regards,


Paolo.

Seems to me a bug in their miniport driver. If you don't own the driver, you
*could* probably workaround it by unchecking "Hide modes that this monitor
cannot display" box in the display advanced property page.

Hi Calvin,

Unfortunately the checkbox you indicated is disabled and anyway the
field only lists the frequency (60Hz, 70Hz and 75Hz).

I was wondering if there is some registry key I can add or remove to
prevent the video card from setting itself based on the monitor type, I
mean to remove the PnP capability in order to have always the full list
of available resolutions even if the monitor doesn't support them.

I tried to play with registry keys and values but without a manual is
quite a hard task.

Thanks anyway,

Paolo.

Force the "default monitor" driver package to be installed for your Samsung
manually.
