Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions. To find out if your PC supports this, select Settings > System > Display. Under Brightness and color, look for the Change brightness automatically when lighting changes check box, and then select it to use this feature. This automatic setting helps make sure your screen is readable wherever you go. Even if you use it, you can still move the Change brightness for the built-in display slider to fine-tune the brightness level.

Adjusting the display settings on a new computer is easy to do. It's important to know how to adjust the brightness on Windows 10 and Windows 11 because if you get eye strain or headaches, the display brightness could be the culprit. Fortunately, you can adjust the levels manually or automatically based on parameters like battery life or the surrounding light.
If the slider is unavailable, it will be due to one of two things. If you're using an external monitor, use the buttons on that to change the brightness. Otherwise, you need to update the display driver.
If this applies to you, consult your monitor's documentation for guidance on adjusting the brightness because the exact instructions will vary per monitor. You should have buttons on your monitor that bring up an on-screen display, which you can navigate through to alter the brightness.
Your display driver manufacturer will have its own control panel from where you can control brightness. For example, there's the Intel Graphics Control Panel and the NVIDIA Control Panel. Which one you'll use or have depends on what graphics card you have.
Most of the laptops I've owned have been fine, however several Windows versions (including Windows 10) have had this occasional bug where the brightness controls will stop working when I wake the computer up from sleep. This results in the Brightness button in the Windows Tray not doing anything when clicked.
Start Device Manager (I use Win+X M). Select "Show devices by type" in the View menu, and then find your device under "Monitors". On a laptop with no external displays attached, there should be only one. With the device selected, click the "disable device" button in the menu bar, and confirm in the popup dialog. This did not turn my display off when I tried it, but it flickered. Then enable the device again with the button. My brightness controls worked again at this point.
but for your scenario, I suspect that display driver has something wrong, when PC awaken from sleep, system will re-load graphic adapter driver, if there is any issue occurred in this process, screen display will show some problems, such as brightness control not working problem.
I tested out the theory today when connecting the displays to a Windows PC. Prior to connecting the Windows PC, I set the brightness of each display using my Mac. Then I unplugged the Mac and plugged up the PC. Sure enough, the brightness remained at the same level as previously set using the Mac. Woohoo!
@OatisB1 - Can you confirm which firmware you are running on your displays? Is it 15.4 (19E241)? Also are you able to then adjust the brightness using a Windows computer or does it just stick to the last setting you used when connected to a Mac?
Yes, are you saying you are able to control the brightness using your PC? I am contempt with it not blinding me. Just trying to see if you are still having the overly brightness issue. The only other thing I changed is i needed a longer Thunderbolt cable so I purchased an OWC Thunderbolt 4 longer cable.
The people that have tested the display indicate there is no brightness provision to use with a Windows PC. The display was designed specifically for Apple computers. Perhaps in a future release Apple will provide that feature.
I'm looking for a way to adjust the brightness of a display, which is connected via HDMI to a Dragonboard 410c with Windows IoT Core installed. I read that DCC/CI can control the brightness over HDMI, tested that already with an OpenSource tool called "Monitorian" on my Windows 10 machine, which does work. This tool is written in C# but relies on "DllImport", with which i absolutely have no experience. So the question is, is it possible, to control the brightness from my UWP code somehow?
I'm using Ubuntu Trusty tahr and I've noticed that there is no brightness control (like a slider), In windows I'll use Intel's graphics media accelerator to reduce brightness but here it looks impossible.
This answer relies on the dbus interface, which alters the actual brightness setting, represented by a file in /sys/class/backlight's sub-folder. Thus , through using dbus we actually control the hardware.
You can also adjust the display brightness from within Windows as well. This is especially helpful if your keyboard doesn't have these keys, or if you're using a tablet and you have to do it within software.
Look for "brightness" buttons on the display and use them to adjust the display brightness. You may instead need to press some sort of "Menu" or "Options" button before you can access an on-screen display that will allow you to increase or decrease the brightness. You'll often find these buttons near the power button on a computer monitor. With some monitors, you may also be able to adjust your screen's brightness with an app like ScreenBright or Display Tuner, though they won't work with all monitors.
You can set different display brightness levels on your laptop or tablet based on whether or not you're plugged into an outlet or not. For example, you could have it set to a high brightness level when you're plugged in, and a lower one when you're on battery power. Windows would then automatically adjust your brightness.
Many modern laptops and tablets have an ambient brightness sensor, which works similarly to the one found on smartphones and tablets. Windows can use the sensor for "adaptive brightness," automatically increasing your display brightness when you're in a bright area, and decreasing the brightness when you're in a dark room.
This is convenient, but some people find that it gets in the way, too. It may automatically decrease or increase your display brightness when you don't want it to, and you may prefer managing brightness manually with the settings above. You may want to try it on and off to decide which you like better.
Expand the "Display" section here, and then expand the "Enable adaptive brightness" section. The options here let you control whether adaptive brightness is used when you're on battery or when you're plugged in. For example, you could disable it when you're plugged in and leave it enabled when you're on battery power.
In this article, I will describe my journey and challenges I faced when building display-dj, a cross-platform desktop application to control integrated laptop display brightness along with external display brightness.
Normally when this happens, I have to manually tune each monitors one by one with their physical controls and also update the display individually. This change should be easier with a few keystrokes or mouse clicks, and not you fiddling with physical controls and clicking on components that are buried deep underneath nested System Preference menus.
So I decided to make a second version of the UI to hide the complexity of the sliders in 2 modes. Mode 1 (collapsed mode) allows you to change brightness of all monitors and mode 2 (expanded mode) allows you to update individual display brightness. You clicked on the top right expansion icon to go between mode. At the end, version 2 is what I settled with the final app.
Then I spent majority of my time debugging and investigating how to control the brightness of the internal display as well as those external displays using pure software instead of physical controls. This is when things get really complicated really quickly.
For Windows, internal display brightness can be controlled using the WMI (Windows Management Instrumentation). Below are the snippets of the script I used to get and update internal display brightness.
Using AppleScript to send a keyboard event for brightness down and brightness up. But this option does not give you a more refined control such as change the brightness to 80% instead of just going up or down by a notch.
Things don't look any better with external displays. For external displays, we have a protocol called DDC/CI (Display Data Channel / Control Interface). This protocol is supposed to make controlling external monitors with software easier, but in reality vendors choose to do their own things and implemented part of the protocol. We ended up with a lot of discrepancy. This makes it nearly impossible to support a wide array of displays and setups.
For Mac OSX, I ended up using a CLI tool called ddcctl. Given the same setup I have at home, mac support for DDC/CI is pretty inconsistent. ddcctl seems to fail intermittently trying to get the current brightness level of the same external display. So I ended up caching the last known brightness of each display and use that instead as a fallback when ddcctl failed.
This application requires a few extra dependencies in the form of binaries such as ddcctl and brightness for mac and volume helper for windows to run. Initially I would ask the users of the application to download and install these dependencies manually.
Dimmer is a small and free application for Windows, designed to help you adjust the brightness of your computer screen, monitor or display. This becomes very useful when you are in near or total darkness and the minimum brightness from your display or screen is still too much. Dimmer offers a fast and easy way to correct this, so you can adjust the brightness of your displays. It can dim all your screens and monitors; LCD, TFT and LED backlit types (even old CRTs). It supports multiple screens, displays and monitors with convenient individual controls to adjust each one.
