How do I adjust my brightness or contrast on my laptop?

Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast helps you change your settings.

Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys, as shown in the picture below, increases and decreases the brightness.

Other examples also shown in the above picture include pressing Fn and F1 and F2 or F7 and F8 to increase and decrease the brightness. If none of the above examples resemble your keyboard, look for keys on the keyboard that have pictures of a sun or a half moon to identify the correct key to adjust the brightness.

How can I adjust the laptop contrast?

Laptops only allow users to adjust the brightness of their screen. Contrast settings are not adjustable on a laptop display.

How do I save the new adjusted settings?

After adjusting your laptops brightness it will retain the new settings. If the brightness settings are not retained after a computer restart, the settings may be getting overridden by brightness settings within the laptop power plan in effect. You need to adjust the brightness for the power plan, which can be done through Display settings.

Adjust laptop brightness through Display settings

You can also adjust brightness through the Display settings in the Control Panel. Open the Control Panel and open the Display option. Look for a link or option titled Adjust brightness, or something similar. This option allows you to adjust the laptop brightness based on the power plan or setting being used, whether the laptop is running on AC power or battery power. Modify the applicable power plan and set the brightness to the desired level. These brightness settings will still be in effect after the computer is restarted.

Laptop brightness is still not enough or screen is black

If after following the above steps your brightness is still not enough, plug your laptop into the wall to make sure it is not an AC power setting that is decreasing the brightness. If the laptop is plugged in but still is not bright enough, try the suggestions on the link below.

Adjusting the brightness using the keys on my keyboard does not work

If the keys on your keyboard are not working, and you are pressing the Fn key and brightness key at the same time it is likely your computer has a driver problem or a power setting is set to low. Typically this happens after updating the video drivers to an incompatible driver or a driver that has problems.

First, if you are running Windows try changing your power settings to "High Performance."

Monitor drivers can also cause this problem. To resolve any potential monitor related issues, re-install the monitor by following the steps below.

  1. Open the Windows Device Manager
  2. Click the + or arrow next to Monitors to expand the Monitors.
  3. Highlight any detected monitors under Monitors and press delete to remove them from the computer.
  4. Once Monitors has been removed from Device Manager under Action click Scan for Hardware changes to let Windows re-detect the monitor drivers.

Finally, we also recommend downloading the latest video drivers directly from the video card manufacturer. If this problem was caused because you updated the drivers install an earlier version of the video drivers.
