I have a Westinghouse LCM-22w3, 22" LCD screen that I was working
perfectly fine with on an XP Pro Dell Pentium IV based system. In that
machine was an AGP slot that I had equipped with a EVGA GeForce 7600
GS card.

So a little less than a week ago I replaced my dell with a new Gateway
GT5620. The GT5620 came with on-board Intel video, so the same day I
bought it I replaced the on-board video with a PCI-E based version of
the GeForce 7600 GS card, again by EVGA.

On the new system, regardless of how much tweaking I do to monitor and
graphic card advanced settings the image is very noticeably off. I
have contrast problems regardless of what I do. I can still plug in my
old system and see that it's not a problem with the monitor itself, so
I am suspecting it's either a problem with the Vista driver for my
video card or with the monitor driver.

I posted several days ago regarding the monitor dimming after the
welcome screen and I have sense resolved that, but when I resolved
that issue I discovered that the dimming effect I was seeing was the
nVidia driver applying my custom setting (contrast, brightness, gamma,
etc...) once I removed this the screen was brighter, but the contrast
problems even more defined.

So are their cases of LCD monitors performing great under XP and
having these sort of issues under Vista? I contacted the monitor
vendor and their response was "we have no Vista driver, the generic
pnp driver should work fine".

I also tried my wifes EVGA GeForce 7200 PCI-E card and once driver was
properly configured I still had the same problem with that card. So
I'm thinking about trying an ATI based card next.

The BIOS settings for the on-board video are set to PCI-E, but the
problem is the same for PCI-E or Auto.

See my response to your previous thread about your nVidia settings.

Are you using the DB15 Analog or the DVI interface ?

There could be quite a bit of difference in quality between the two.
