I have a MSI S420 laptop and I'd like to control the contrast of its screen. Unfortunately, only brightness can be adjusted through the keyboard. I tried ddccontrol, but it says that my monitor doesn't support DDC/CI. Only the Windows version of ATI Control Center offers controls to adjust the contrast. It's very annoying, the colors are all messed up. Is there anything else I could try?
Thanks for your help,
if you have Ati control center in Windows, you most probably have amdcccle. Try it.
