Recently, I bought a Surface Pro 2 tablet and one of the first dilemmas I had was about changing the brightness of the screen. How do you do that in Windows 8 or Windows 8.1, since there are no hardware buttons for this task available on the device? Apparently, the procedure involved is very easy and it involves only a few taps.
Changing the Brightness is Done Using the Settings Charm
On your Windows 8 or Windows 8.1 tablet, bring up the charms. If you don't know how, read this guide: What are the Charms & How to Use them.
Then, tap Settings.
On the bottom of the Settings charm you will find several buttons. Look for the one named Screen and tap on it.
A slider is displayed, for increasing or lowering the brightness of the screen.
Move the slider up or down, depending on how you want to set the brightness. When done, tap somewhere outside the Settings charm to make the it disappear from the screen.
I hope you found this guide useful. If you also own a tablet with Windows 8 or Windows 8.1 or a hybrid device, don't hesitate to share in the comments form below the problems and questions you have not answered yet. We will take your comments into consideration when creating new tutorials.
