Where is the OSD button on my laptop.

[Cassiel27]

I NEED to fix the color contrast on my computer because none of the colors are correct, but it says I need to press an OSD button. I have looked through every manual it could possibly be in, and scoured the internet. But nothing shows or tells me where it could be. I'm on a laptop, there is no button, the keyboard shortcut if there is one isn't listed. There is no button in front of my monitor because it's a laptop, there isn't one on the sides, I don't even know what the "bezel" of a laptop is. Please. Where is it. I just want normal colors. Teach it to me like I'm stupid, with pictures if at all possible.

Are you talking about an EXTERNAL monitor ? For the notebook display, you have to use utilities from Windows (some machines may have F* keys). Please use

               Turn high contrast mode on or off in Windows
