Are you struggling to see the contents on your Dell laptop screen? Adjusting the brightness of your screen can help you see the text, images, and videos better, while also reducing eye strain. In this article, we’ll guide you on how to make your computer screen brighter on your Dell laptop.

Why Adjusting Screen Brightness Is Important

Before diving into how to adjust your Dell laptop screen’s brightness, let’s understand why it is important. Our eyes are sensitive to light, and prolonged exposure to bright screens can cause eye strain, headaches, and even damage to our vision. Additionally, if you’re working in a brightly-lit environment, adjusting your screen brightness can help reduce glare and make it easier to see what’s on your screen.

Step-by-Step Guide: How To Make Your Dell Laptop Screen Brighter

Now that we’ve established the importance of adjusting screen brightness, let’s get into the steps to do so on your Dell laptop.

Step 1: Locate the Function Key

On most Dell laptops, the Function (Fn) key is located in the bottom left corner of the keyboard. It is typically marked with a “Fn” symbol.

Step 2: Locate the Brightness Key

Next, look for the brightness key on your keyboard. It is usually one of the function keys, marked with a sun icon or the words “brightness up” or “brightness down.” On Dell laptops, this key is often located on the F11 or F12 key.

Step 3: Adjust Brightness

Press and hold the Function (Fn) key, and then press the brightness key to adjust the screen brightness. The sun icon on the key should change to indicate whether you’re increasing or decreasing the brightness.

Alternatively, you can adjust the brightness through the Windows settings. Here’s how:

Step 4: Open Windows Settings

Click on the Windows Start menu and select “Settings” (the gear icon).

Step 5: Go to System Settings

In the Settings menu, select “System.”

Step 6: Open Display Settings

Under the System settings, click on “Display.”

Step 7: Adjust Brightness

Scroll down to the “Brightness and color” section and use the slider to adjust the brightness. You can also toggle on the “Change brightness automatically when lighting changes” setting to have your laptop adjust the brightness according to the ambient light in the room.

Other Tips To Improve Screen Visibility

Adjusting screen brightness is not the only way to improve screen visibility. Here are some additional tips:

Tip 1: Adjust Text Size

If you’re having trouble reading text on your screen, try adjusting the text size. You can do this in the Windows settings under “Ease of Access > Display.”

Tip 2: Reduce Blue Light

Blue light emitted by screens can cause eye strain and disrupt sleep patterns. Consider using a blue light filter app or enabling the built-in Night Light mode in Windows 10 to reduce blue light.

Tip 3: Clean Your Screen

A dirty screen can reduce visibility. Clean your screen regularly with a soft, dry cloth.
