    This only take a moment. Once the driver has uninstalled, your Device Manager list will refresh, and you will notice that the "Monitor" category is gone.
  11. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/1f\/Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-14-Version-3.jpg\/v4-460px-Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-14-Version-3.jpg","bigUrl":"\/images\/thumb\/1\/1f\/Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-14-Version-3.jpg\/aid1714483-v4-728px-Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-14-Version-3.jpg","smallWidth":460,"smallHeight":347,"bigWidth":728,"bigHeight":549,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a> (screenshot)<br>\n<\/p><\/div>"}
    It's the square, computer monitor-shaped button at the top of the Device Manager window. Doing so will reinstall and update the driver that you just removed.
  12. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/8\/89\/Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-15-Version-3.jpg\/v4-460px-Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-15-Version-3.jpg","bigUrl":"\/images\/thumb\/8\/89\/Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-15-Version-3.jpg\/aid1714483-v4-728px-Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-15-Version-3.jpg","smallWidth":460,"smallHeight":344,"bigWidth":728,"bigHeight":545,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a> (screenshot)<br>\n<\/p><\/div>"}
    Once the Device Manager scans for changes, it will automatically reinstall the basic Microsoft driver for your monitor. This should re-enable the brightness slider.
  13. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/e\/e8\/Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-16-Version-3.jpg\/v4-460px-Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-16-Version-3.jpg","bigUrl":"\/images\/thumb\/e\/e8\/Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-16-Version-3.jpg\/aid1714483-v4-728px-Control-the-Brightness-of-Your-Computer-With-Windows-7-Step-16-Version-3.jpg","smallWidth":460,"smallHeight":344,"bigWidth":728,"bigHeight":545,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a> (screenshot)<br>\n<\/p><\/div>"}
    This may not be necessary for your changes to take effect, but can't hurt and may save you a step later.

    Try to adjust your brightness . Once your computer reboots, click the Power Options button in the System Tray to find your restored brightness options. [3]

    Community Answer
    You can find it in "control panel." Press the start icon with the flag in the bottom left and then select something called "control panel." Once in there, type, "Display Brightness" on the search bar and it should pull up a setting to change it!

  • Question
    I was reducing the brightness on the monitor and it went all black. How do I fix it?
    Community Answer
    First, make sure you didn't turn the brightness all the way down. If that's not the issue, reboot your PC or try to update your graphics driver.
