How to automate setting of gamma, contrast and brightness (ati card).

[fusion400 0]

Hello i am wondering how i can automate the setting of gamma, contrast and brightness

i need to change gamma, contrast and brightness on a large number of computers

which are using ati 4200 cards with catalyst control center installed.

I need to automate this procedure somehow.

There are registry entries but nothing happens when i try and change them.

When i try to change in Catalyst control center these values do not change.

I have run Process Monitor to try and isolate where it changes the registry values

for brightness, contrast and gamma but i just can not find the entry.

"ColourDesktopGamma_DEF"="1.0 1.0 1.0"

"ColourDesktopBrightness_DEF"="0 0 0"

"ColourDesktopContrast_DEF"="1.0 1.0 1.0"

So i am wondering can the automation be done.

Ideally i just want to set everything through simple console commands.

But i can not find any info about it.

Hi.

procmon.exe is a good start to catch the location of the settings.

Narrow the displayed results by *ONLY* displaying write & success. (REG & maybe FILE)

If you don't know, where the info goes to, you hardly can automate it.

After altering values manually *WITHOUT* using the ATI GUI, a reboot might be required, before they take effect.

Regards, Rudi.

Starting Point, you have to login/signup to access the files though.

I use GammaPanel, its a no-install program that writes to an ini file.
