I've been experimenting with different monitors with my trick, but found out it only works with conventionals.
Okay here's the trick:
If you want accurate brightness and contrast try this:
Go into you screens Brightness and Contrast controls ( it may be an OSD or little lights will appear on the screen) and set the contrast as high as it will go. Then, put the brightness as low as it will go.
Now you should have an accurate brightness. Take a step back and look!
