Here is a hardware profile for *my* Asus mb169+ monitor. Sample variation may result in the profile not working as well for you, but it's probably better than the default. I got much better definition in highlights. It's not perfect, but it's the best I can do. And it's on par with a lot of mainstream monitors, which the default profile is not.
