Strange brightness issue with my Geforce 8600GT (Gigabyte) and mySamsung 6187 LED...

I'm having a really odd issue with my card.. or perhaps its what i'm
trying to do with it...

I have 2 westinghouse 24" widescreens in my one office.. but running
into the living room i have a dvi to hdmi cable so i can output one of
the two ports to my Samsung 6187 tv..

I'm basically pulling out one port that goes to one LCD and swapping
it for the samsung one..

When i do this.. if i leave the system in dual screen mode.. things so
far seem fine, switching back and forth..

When i change in the nvidia control panel to single screen mode.. even
on my LCDs.. i get this very darkened look to the screen.. the start
menu has no contrast etc..

**Also.. if i try to save then load a profile in nvidia panel.. it
will say something like "profile load failed".. i've run the nfr
utiltiy to remove the drivers.. started fresh.. same deal overall..

So i'm not sure if this is a problem with the card or the drivers.. or
Vista x64.

Thanks

Have you checked the Gamma settings in the nVidia control panel?

This appears to be part of the issue.. its definitely driver related
(latest driver and the one before it)..

True.. if i switch resolutions.. i get the darkening effect.. on
either the tv or the lcd.. i also get "error loading profile" when
trying to load nvidia profiles..

If i up the gammo to say 80% or higher... It looks more normal.. or i
can just reboot (very annoying).. but if i up the gamma then reboot..
i'm sure it would be too bright.

So even though the gamma isnt actually changing.. it appears to be
changing.. I'm still leaning towards crappy drivers for x64 Vista
perhaps.
