9 Ways to Adjust Screen Brightness on Your Windows 10 PC

Adjusting the brightness of the screen can improve eye health and comfort. Here’s how to change brightness in Windows 10.

It’s easy to adjust the display settings on your new computer. It’s important to know how to adjust brightness in Windows 10 because if you experience eye strain or headaches, the display’s brightness could be the cause. Luckily, you can adjust the levels manually or automatically based on parameters like battery life or ambient light.

Whether you want to reduce or increase the light, we’re going to show you how to adjust your screen brightness in Windows 10.

Change Brightness in Windows 10 in Settings

One of the easy ways to control the brightness of Windows 10 is to use Settings.

1. Press Win + I to open Settings.
2. Go to System> Display.
3. Below Brightness and Color, use the Change brightness slider. It will be darker on the left side, and lighter on the right side.

If a slider is unavailable, it will be due to one of two things. If you are using an external monitor, use the buttons on it to change the brightness. Otherwise, you need to update your display driver.

In addition to optimizing the keyboard to your preferred operating system, the software allows you to customize the K380 to suit your individual needs and style.

I’m afraid so. Do you need to have additional software installed for specialty keys like Mission Control to work or work out of the box?

I used to think of buying MX Keys, if I do, I will try to get to the bottom of it.

Yes, I have Logitech Options installed, but was pretty sure the keys were working before I installed it. I just tried it on my Macbook but forgot it had options for the mouse already installed. If I have the opportunity, I will uninstall the software and test it again.

I looked at it a bit again, could you please test this new playground to see if it produces any output when the brightness keys are pressed?

On many Windows laptops, you may need to press a function key (F1-F12) to turn on the keyboard backlight. In this case, which function key you choose will likely depend on the make and model of your laptop.

FEATURES

Enhance your keyboard with Logitech Options

Unlock the hidden potential of your keyboard by adding Logitech Options software.

In addition to optimizing the K380 for the operating system, Logitech Options allows you to customize the keyboard to suit your needs and style – create shortcuts, reassign key functions, turn keys on (and off), display battery alerts and much more.

Logitech Options software is available for Windows (7, 8 or later) and Mac OS X (10.10 or later).

Install Logitech Options: Mac or Windows

Shortcuts and function keys

Hotkeys and multimedia keys

The table below shows the shortcut and multimedia keys available for Windows, Mac OS X, Android, and iOS.

To perform a shortcut, hold down the fn (function) key while pressing the key associated with the action.

The table below lists the function key combinations for different operating systems.

If you usually use function keys more often than hotkeys, install the Logitech software and use it to configure hotkeys as function keys and use the keys to perform functions without holding down the fn key.

OS-adaptive keyboard

Logitech Keyboard K380 includes OS-adaptive keys that have different functions depending on the operating system of the device you’re typing on.

The keyboard automatically detects the operating system on the currently selected device and remaps the keys to make functions and shortcuts right where you want them.

If the keyboard does not correctly detect the operating system of the device, you can manually select the operating system by pressing and holding (3 seconds) the function key combination.

Unique multi-function keys make the Logitech Keyboard K380 compatible with most computers and mobile devices. Key label colors and split lines identify functions or symbols reserved for different devices and operating systems.

The color of the key label

Gray labels indicate functions available on Apple devices running Mac OS X or iOS. The white labels on the gray circles represent symbols reserved for use with Alt Gr on Windows computers.*

The modifier keys on either side of the space bar display two sets of labels separated by dividers. The label above the split line shows the modifier sent to a Windows, Android, or Chrome device. The label under the split line shows the modifier sent to an Apple Macintosh, iPhone® or iPad®. The keyboard automatically uses modifiers associated with the currently selected device.

* The Alt Gr (or Alt Graph) key, which appears on many international keyboards, replaces the right Alt key, which is usually found to the right of the spacebar. When pressed in conjunction with other keys, Alt Gr allows you to enter special characters.

Most computer monitors have multiple settings such as brightness, contrast, and color settings. They can often be tweaked with a set of clunky menus with buttons hidden on the side of the display. However, by going to a third-party app, you can adjust these settings via an icon on the systray or even via a quick keyboard shortcut.

How to reverse the F-Keys of Logitech K380 Keyboard

I have been using the Logitech K380 keyboard for about a week and am very happy with it.

I like it because it’s quiet, a bit on the load, and can be plugged in and quickly switched to 3 devices at the push of a button.

When I got it after pressing the F keys, its default behavior is to use alternative features like volume and media controls.

If I want to use F1 or F2 I have to click on the fn key and then press the F key. As someone who uses a lot of function keys due to my work, this is annoying.

Fortunately, I was able to fix this by reversing the behavior of the F keys. Now when I press F11 for full screen my Chrome will work without pressing the fn key.

I think some people call this process Fn Lock

Follow the steps below to reverse the F-keys.

Experimenting with Logitech Options

I did some experiments on Logitech Options to see what happens in different situations. See the results below.

After uninstalling Logitech Options, it reverted the keyboard settings to the previous one. Therefore, Logitech Options software should always be installed to preserve the behavior where you can use the F keys without pressing the fn key.

Logitech Options software is installed locally per user on Windows. When I switch to a different user profile, the F-keys go back to their original settings. I had to install Logitech Options in each user profile for the F keys to work without the fn key.

The same goes for switching to another computer. I had to install Logitech Options on all user profiles.

To switch to another device on the Logitech K380, I have to press the fn key and then F1 / F2 / F3 as switching a Bluetooth device is already an alternate function.

Hope this helps you reverse the alternate function of the F keys on your Logitech K380 keyboard.

Use the function keys by holding down the fn key and pressing the shortcut key associated with the function number and action. The table below describes the special key combinations for different operating systems.

Use the Touch Bar

Some MacBook models may require you to adjust the keyboard backlight using the Touch Bar. To do this, tap the arrow icon on the touch bar to expand the control bar. To turn on the backlight, tap the Increase brightness button. To turn it off, touch and hold the Decrease brightness button, which looks like a semicircle with dots rather than radii.

These instructions should work on MacBooks with Touch Strips running MacOS Monterey and Big Sur.

Adjust it in Control Center or Windows Mobility Center

Depending on the manufacturer and model of the device, you can turn on / adjust the keyboard backlight using the computer control panel menu.

On some MacBooks, this means opening the Control Center, selecting the brightness of the keyboard, then dragging the appropriate slider. This should work for some MacBook models that also run MacOS Monterey or Big Sur.

For some Windows 10 computers, this means you need to access Windows Mobility Center, which is located in the Control Panel. To access it, go to Control Panel> Hardware and Sound> Windows Mobility Center. In Windows Mobility Center, look for the Keyboard Brightness (or Keyboard Backlight) setting, select the appropriate slider, and drag this slider to the right.

To bring some clarity to this situation, we’ve gathered six possible ways to turn the keyboard backlight on or off. Read on to find the best method for your laptop or desktop keyboard.

Use the function keys by holding down the fn key and pressing the shortcut key associated with the function number and action. The table below describes the special key combinations for different operating systems.

If you usually use function keys more often than hotkeys, you can install Logitech software and use it to configure hotkeys as function keys that you can press directly (without having to hold down the fn key).

Note: An asterisk (*) indicates activities that require Logitech software to be installed.

REPLACE THE BATTERIES

Slide the battery compartment door towards the on / off switch and raise the door.

Replace the old batteries with two new AAA batteries and reattach the compartment door.

COMPATIBLE DEVICES

Logitech Keyboard K480 works with Bluetooth wireless-enabled computers, tablets, and smartphones that support external keyboards.

• Windows® OS version 7 and above
• Mac OS® X 10.9 or later • Chrome OS™
• Apple® iPhone and iPad, iOS® 5 or later
• A tablet or smartphone with the Android ™ operating system, Android 3.2 or later

Note: An internet connection is required to download Logitech software.

Fortunately, I was able to fix this by reversing the behavior of the F keys. Now when I press F11 for full screen my Chrome will work without pressing the fn key.

Set Up ClickMonitorDDC

Download ClickMonitorDDC – the installer or portable version you can unpack anywhere – and run it. An icon will appear in the system tray, but you can expand it to display all the ClickMonitorDDC icons, each representing a different setting that you can customize.

Click one to see a full window that allows you to click and drag the sliders to achieve the brightness you want. You can even switch between built-in monitor settings like Movie or FPS Gaming, although only one of mine actually matched the name to the setting. The others were just random numbers, so it took a bit of trial and error to figure out which is which.

This panel itself is incredibly handy, and if all you need is the occasional tweak then feel free to stop there. But if you right-click on one of the ClickMonitorDDC icons, you can enter Settings, which has tons of handy customizations. There’s a lot to check out here, but one place you should definitely start with is the shortcuts.

Create Shortcuts

If you click Manage Mouse, Manage Shortcut Keys or Time Transfer Limits, you can customize your own mouse shortcuts, keyboard shortcuts or schedules accordingly. This allows, say, to adjust the brightness using Ctrl + Shift + MouseWheel, or set the brightness to automatically dim 50 percent at night.

To do this, select a shortcut and enter one of the ClickMonitorDDC command line commands – they are very simple and you will find them on the main page of the application. So the command b 100 will set the brightness to 100, and b + 20 will increase the brightness by 20 points. Search the list and look at the ClickMonitorDDC examples for ideas. It is quite powerful when you set it up the way you like it.

If ClickMonitorDDC isn’t working for you, it’s worth trying an alternative such as ScreenBright (whose site is already down, but you can still find it on sites like Softpedia). It’s not that powerful, but I’ve encountered situations where one DDC / CI program works and another doesn’t, so it’s always worth a try.
