lost brightness slider

If the brightness slider is missing on your Windows 11 device, it could be due to a few reasons related to graphics drivers. Here are some steps you can take:

1. Check for Windows Updates: Sometimes, Windows Update can provide the necessary drivers that might be missing. Go to Settings > Windows Update and check for updates.
2. Update Graphics Drivers: Since you've already tried updating the Intel graphics driver, ensure that you are downloading the latest version directly from the Intel website or your device manufacturer's website. Sometimes, the drivers provided through Windows Update may not be the most current.
3. Reinstall Graphics Drivers: If you are nervous about uninstalling the driver, you can use the Device Manager to uninstall the driver safely. After uninstalling, restart your computer, and Windows should automatically reinstall the default driver. To do this:
   • Right-click on the Start button and select Device Manager.
   • Expand the Display adapters section.
   • Right-click on your Intel graphics driver and select Uninstall device. Make sure to check the box that says "Delete the driver software for this device" if prompted.
   • Restart your computer.
4. Use Microsoft Basic Display Adapter: If the issue persists, your system might be using the Microsoft Basic Display Adapter, which has limited functionality. You can check this in Device Manager under Display adapters.
5. Check Power Settings: Sometimes, power settings can affect display options. Go to Settings > System > Power & battery and ensure that your power plan is set to Balanced or High performance.

If these steps do not resolve the issue, consider reaching out to your device manufacturer for further assistance.

Don't worry, if you uninstall the Graphics driver, it will revert to the Microsoft Display driver.

Please follow the steps below to uninstall the Graphics driver from the Device Manager.

Start by right-clicking the Start button and selecting Device Manager. In the Device Manager window, scroll down and expand Display adapters. Right-click your Intel R graphics card and choose Uninstall device. A confirmation box will appear—make sure to check Attempt to remove the driver for this device if the option is available, then click Uninstall.
