color correction - digital vibrance

hi ... in my NVIDIA driver options in windoze there is an option in nview for color correction called digital vibrance ... i like to set this to high as the colors in video and games look more vivid..

my question is: Is there an equivalent option for the NVIDIA linux drivers and if so, how do i set it? How can i make it so its always set?

any reply''s / help greatly appreciated :-)

This option exists for linux too but it works a little different. On windows you can change Digitalvibrance on the fly. On linux digitalvibrance is a special option for the XF86Config(-4) file. To activate the changes you need to restart X.

To use DVC add a line:
Option "DigitalVibrance" "x" to your screen or device section of your XF86Config(-4) file.

Where "x" is 0 (0ff), 1(low), 2(medium) or 3(high).

I was wondering if there is any option to set brightness and contrast from the driver like in windows. For some reason the screen comes from the factory way too bright. I tried to set the OSD controls on my screen at 0 for brightness and contrast and it is still too bright.

I also tried the xgamma -gamma X.X command, that help a lot , but it is still too bright. I am getting very frustrated here, linux is great, but I cant stand that brightness. Any help will be very appreciated.

Thanks in advanced.

What were you using for a gamma value? I believe the lowest is 0.001 (at least, the man page says they're passed with 3 digits of accuracy -- I'm just not sure on whether they can be negative or not)...

My values for xgamma are as follows:

[root@amd root]# xgamma
-> Red 0.500, Green 0.500, Blue 0.500

Any advice will be appreciatted.

Well, try setting it to 0.05 instead of 0.5. That'll be ten times less bright as it is currently, that should help at least a bit...
