Windows 10 does have a brightness slider, but its visibility may vary depending on the device and specific configuration. There could be a few reasons why a brightness slider is not readily accessible on some Windows 10 devices. Here are a few possibilities:
1. Device-specific settings: Some devices, especially older models, might have dedicated hardware buttons or keys for controlling display brightness instead of a software-based slider. In such cases, you’ll need to use the designated hardware controls to adjust the brightness.
2. Power plan settings: Windows 10 allows different power plans with customized settings. It’s possible that your current power plan has certain settings that limit or hide the display brightness option. To adjust this, follow these steps:
a. Open the Start menu and go to Settings.
b. Select System and then click on Power & sleep.
c. Under the Related settings section, click on Additional power settings.
d. In the Power Options window, select the power plan you are currently using and click on Change plan settings.
e. Click on Change advanced power settings.
f. Look for Display in the list and expand it.
g. Expand the sub-menu called Display brightness and ensure that the setting is not set to 0% or disabled.
3. Outdated or incompatible display drivers: Display drivers play a crucial role in enabling the functionality of certain features, including the brightness slider. If your device has outdated or incompatible display drivers, it could affect the visibility or availability of the brightness slider. Updating your display drivers to the latest version from the manufacturer’s website or using Windows Device Manager may help resolve this issue.
4. External display limitations: If you are using an external monitor or display, the brightness adjustment might be controlled directly from the monitor itself. In such cases, you won’t find a brightness slider in the Windows 10 settings. Refer to your monitor’s user manual for instructions on adjusting the brightness.
5. Accessibility settings: Windows 10 provides various accessibility options, and it’s possible that adjustments made in these settings can affect the visibility of the brightness slider. To check this:
a. Open the Start menu and go to Settings.
b. Select Ease of Access and then click on Display.
c. Ensure that the "Change brightness automatically when lighting changes" option is turned off.
By checking these possible scenarios, you should be able to determine why the brightness slider is not available on your Windows 10 device and take appropriate steps to rectify the issue.

Why is there no option for brightness on Windows 11?
The lack of a brightness option on Windows 11 may be a result of several factors. Here are a few possible reasons:
1. User Interface Changes: Windows 11 introduced a new design philosophy focused on simplicity and minimalism. As a result, some features and options that were available in previous versions may have been reworked or relocated to streamline the user experience. It’s possible that the brightness control was moved to a different location or integrated into the system settings.
2. Windows Auto-Brightness Feature: Windows has a built-in auto-brightness feature that adjusts the display brightness based on ambient lighting conditions. In Windows 11, this feature may be enabled by default, which could explain the absence of a manual brightness option. Check the display settings to see if the auto-brightness setting is turned on or if there are any related controls that can be customized.
3. Device-Specific Limitations: Different computer hardware manufacturers may have different ways of implementing brightness controls in their devices. It’s possible that some devices are not fully supported or optimized for Windows 11 yet, resulting in certain features, such as brightness control, being temporarily unavailable. It’s advisable to check for driver updates specific to your device or contact the manufacturer’s support for further assistance.
4. Software Bug or Glitch: Like any new operating system release, Windows 11 may have its share of bugs or glitches in its initial stages. The absence of a brightness option could be due to a software issue that may be addressed in future updates or patches. Keeping your system up-to-date with the latest Windows updates might resolve the issue if it is software-related.
To troubleshoot further, I recommend exploring the display settings menu in Windows 11 thoroughly. Look for options related to brightness, display, or power management. Additionally, researching online forums and communities dedicated to Windows 11 might provide insights from other users experiencing similar issues.

Why is my brightness slider missing?
If you find that your brightness slider is missing on your iPhone, there could be a few reasons for this. Here are some steps to troubleshoot and understand why the brightness slider is not visible:
1. Check for software updates: Ensure that your iPhone is running the latest version of iOS, which is iOS 16 as of 2023. Software updates often include bug fixes and improvements that can address various issues, including missing features or settings.
2. Restart your iPhone: Sometimes, a simple restart can resolve minor software glitches. Press and hold the power button on your iPhone until the slider appears, then slide it to power off. Wait a few seconds, then press and hold the power button again until the Apple logo appears to turn the device back on.
3. Check display settings: Open the Settings app on your iPhone, then go to Display & Brightness. Make sure that the Auto-Brightness option is enabled. When Auto-Brightness is turned on, your device adjusts the screen brightness based on the lighting conditions around you. If it is disabled, toggle it on and see if the brightness slider reappears.
4. Disable Reduce White Point: In the Display & Brightness settings, check if Reduce White Point is enabled. This feature reduces the intensity of bright colors on the screen, and when enabled, it can affect the visibility of the brightness slider. If it is turned on, toggle it off and see if the slider becomes visible.
5. Reset display settings: If the above steps didn’t help, you can try resetting your display settings to their default values. Go to Settings > General > Reset and tap on Reset All Settings. Keep in mind that this will reset various settings on your device, including network, display, and accessibility settings. Your personal data and media will not be affected.
6. Contact Apple Support: If none of the above steps resolve the issue, it’s recommended to reach out to Apple Support for further assistance. They can provide more specific guidance based on your device and individual circumstances.
Remember, these troubleshooting steps are based on general knowledge and best practices. The exact solution may vary depending on the specific iPhone model, iOS version, or any potential bugs or conflicts.
Why is Windows not allowing brightness change?
There can be various reasons why Windows is not allowing you to change the brightness on your device. Here are a few steps you can take to identify and resolve the issue:
1. Check Power Plan Settings: Sometimes, the power plan settings on your device may be limiting the ability to adjust brightness. Go to the Power Options in the Control Panel and ensure that the "Adjust plan brightness" option is set to a value other than "Do nothing."
