- Windows XP was reinstalled
- Now when I try to change the resolution of this monitor to it's max
1680x1050 @ 32 bits... the highest I can get it is: 1600x900 @ 32
bits
OR 1680x1050 @ 16 bits; it will no longer allow the proper color
quality with the maximum resolution.
- I reinstalled Nvidia drivers and DirectX. No love.
- I went to device manager, uninstalled my monitor, reboot, let
windows re-install it. Still not fixed.
....if anyone has any other good suggestions to try they would be
appreciated, thx
By any chance, is the video card one of the ones that has
a less than full bandwidth DVI port ? There have been
cases, where the output resolution over DVI, is limited
by the "clock" rate that results from the settings choice.
In the table on the following page, you can see resolution
choices, along with the mode used to drive the signal down
the cable, as well as the "dot clock" rate.
http://en.wikipedia.org/wiki/Digital_Visual_Interface
HDTV (1920 × 1080) @ 60 Hz with CVT-RB blanking (139 MHz)
The "139 MHz" on the end, represents the clock signal rate on the
cable from the computer to the DVI equipped monitor. The
real data rate is 10x that speed, or 1390Mbit/sec.
Some video cards, have poor quality digital output. Rather
than admit that, the company that designed them choses to
issue a driver which restricts the resolution choices
the user can make. A fully compliant single link DVI
might be able to run at 165MHz, while "broken" ones
are lower. Sometimes, the resolution choices are
changed between releases. A newer release might be
more restrictive, to "protect" you from seeing the
real problem (bad quality DVI).

In some cases, a different driver helps. Before uninstalling
a driver, it helps to either
1) Store the working driver you discovered in the first place,
in a safe place. All my drivers are stored in a folder called
"installed" for that reason. If I ever need to reinstall
Windows, I just go through my "installed" list one by one.
2) Figure out (somehow), what driver version is currently
being used, before loading a newer driver. Perhaps
Add/Remove can help ?
3) If you only tried one driver, you can try to "rollback"
to the previous driver.
Video drivers are such, that sometimes you have to stop
upgrading them, simply because you got the best (compromise)
version of the driver, some time ago. I have a few machines
here, that I stopped changing drivers on them, because the
new drivers weren't fixing anything.
If it was my card, I might be working backwards, through
the old drivers, to get my functionality back. Nvidia has
archives, if you can figure out how they work. Search for
the word "archive" using the Nvidia.com "search" box. That
is how I found this link.

If you have a bowl of popcorn, and a couple hours, you
can read some of this. It will give you some ideas
about how to hack/fix some of this stuff (getting
your stuff to work, the way you want it to work).

XDIAG Run the tests..Also,maybe the drivers installed
