How to improve contrast on laptops running on battery and Intel Graphic-based

By default, the driver from Intel Graphic will reduce contrast on battery to save on battery life. But if image quality is more important to you than battery life, then there's a way to change that.
First, navigate to Control Panel, and locate “Intel GMA driver for mobile.” That should lead you to a Intel Graphic panel where you can change various settings. Alternatively you can go to your tray icons and locate the Intel Graphic icon, then click on Properties. Once the Intel Graphic window pops up, click on the “Display Setting” tab, then click on the “Power Setting” button. The “Power Setting” window should pop up. Click on “Modify Setting.” Locate the slider labeled “Intel Display Power Saving Technology” and crank the slider to maximum quality.
Now the contrast of your laptop display should be equivalent to what you see when you run your laptop on AC adapter.

The point of that technology is that you can see the things on the screen more clearly when the backlight is on a lower setting and that setting is enabled. The contrast is reduced, but the brightness is increased. That setting is already automatically disabled when you plug your computer in because you won't need to lower your backlight to save power then.

 

That's the problem. I don't know for anybody else, but for me, the brightness is the same whether I am running on battery power or running on AC adapter. So the drop in contrast is really annoying and hurts my eyes. Also, simply dropping the brightness does not make the text clearer. It's still blurry, but the screen is simply less bright.
