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.

How to Automatically Adjust Brightness Based on Ambient Light You can configure different screen brightness levels for different power plans and switch between them, if you like (though we don't think power plans are really necessary). You're probably using the Balanced power plan.Ĭonfigure different screen brightness levels for 'On battery' and 'Plugged in' under 'Adjust plan brightness.' This setting is tied to your power plan. Select 'Hardware and Sound,' select 'Power Options,' and click the 'Change plan settings' link next to the power plan you're using. Windows would then automatically adjust your brightness. 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. 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.

How to Automatically Adjust Brightness When You're Plugged In These are often function keys, which means you may have to press and hold the Fn key on your keyboard, often located near the bottom-left corner of your keyboard, while you press them. To adjust the screen brightness, look for an icon that corresponds to brightness-often a sun logo or something similar-and press the keys. Often, these keys are part of the row of F-keys-that's F1 through F12-that appear above the number row on your keyboard.

On most laptop keyboards, you'll find shortcut keys that allow you to quickly increase and decrease your brightness. How to Adjust Brightness Manually on a Laptop or Tablet Windows can change it based on whether you're plugged in, based on how much battery power you have left, or using an ambient light sensor built into many modern devices.

#Lower brightness windows 7 software

On that forum thread there is another option - MControl, it seems to be shareware though I don't see it anywhere on their site and a person claims it still continues to work after the trial period expired, so you should give it a try.įinally there is even another utility called MagicTune by Samsung that seems to basically do the same, plus a horrible UI and even though DDC is standard, I wouldn't be surprised if their software was locked to only work with their monitors, but you can also give it a try. I suggest you ask someone on the linked forum thread if they still have the software and can send it to you (don't forget to check it on VirusTotal just in case). It supports command line arguments, so you can create shortcuts on your desktop to quickly set the brightness at predefined levels if you wanted to. On Windows, there seems to be a software called ScreenBright, or I should say there used to be since the official site now returns a 404 and the homepage says the content was removed because of technical issues (I guess he had enough of users asking for help because the software didn't work for them). It's basically the equivalent of the obnoxious/ugly UI that your monitor has, but accessible directly from the computer and programmatically if you want to. By talk I don't mean just image data but actual bidirectional communication (it's for example used to query the monitor for its supported resolutions and refresh rates). On desktops it's a little different since the computer can't control the backlight's power (the screen has its own independent power supply), however there is still hope - there is a data bus called DDC that allows a computer to 'talk' to a display over VGA, DVI or HDMI (and most likely DisplayPort also). Brightness control is done by some ACPI magic that's only available in notebooks, and that basically controls the power that goes to the screen's backlight.
