The WmiMonitorBrightnessMethods class is used for setting the screen brightness via the WmiSetBrightness method. though I don't see a method for setting the brightness for an individual screen.? My app has only support for one screen - if you have multiple screens, you'll need to query each separately, as I've understood. Could someone please tell me how to get back the screen brightness slider or suggest an alternative way to adjust brightness. I have had this Windows 7 desktop for more that 9 months and I have never faced this problem. my laptop has only 7 levels while my tablet has 10. Usually this bar displays at the very bottom of Power Options in Windows 7. The WmiMonitorBrightness class offers a handful of read-only properties about the actual brightness settings: Active, CurrentBrightness, InstanceName, Level and Levels.Ī point of interest might be the Level property as it is an array of valid brightnesslevels supported by the hardware. Well, I've used the WMI queries from Samuel Lai and wrapped around the visual stuff. The order of the arguments is not relevant. 25% ) - the level is set to the next higher available level, if the argument is not in the level array

In case of an incompatible system, a message will pop up and the program will quit. I've tested the program on Win7 (x86) - AFAIK, it won't work on ordinary PCs, as they don't have the necessary hardware support for this. O.K., whatever - enough blabla :) Using the Code/Program The Program Later on, I realized that I should have taken a closer look at the IOCTL_VIDEO_QUERY_DISPLAY_BRIGHTNESS Control site as Microsoft says here that this control is no longer supported and one should use the WmiMonitorBrightness Class. but this thread was closed and I found no way to contact him - *lol* - so I tried another workaround some people suggested and screwed up my gamma and contrast settings - haha - finally I found this page of Samuel Lai - he made a simple sidebar gadget using WMI to access the screen brightness control and also provided some code - funny, as during my search I often read people saying that there is no support in C#. Note : Keys on your keyboard maybe on different location depending your laptop brand and model. Using them in combination with Fn should help you adjust the brightness of your screen. First, I hit on the IOCTL_VIDEO_QUERY_DISPLAY_BRIGHTNESS Control but many people struggled with invoking it in C# - in fact, I found only one person that seemed to have managed it. You must have keys marked as shown below on your keyboard. So I searched the web for a simple solution - but had no success. I recently bought a tablet and wasn't quite satisfied with how to change the screen brightness. It also supports commandline arguments to fit your needs. Action Center may be accessed by swiping left on a touchscreen.With this little tool, you can quickly adjust the screen brightness of your laptop or tablet. Change your display’s brightness by clicking (or touching) the slider and dragging it. Tap on “Expand” if you can’t see the slider. It may be accessed by clicking or tapping the notification bubble icon, which is located just to the right of the calendar on the taskbar. In Windows 10, the Action Center has a fast brightness slider.

This is especially useful if your keyboard lacks certain keys, or when you’re using a laptop and go through it within apps. Your display brightness may be adjusted inside Windows. If your computer is an older model and does not have brightness controls on the keyboard, you can still adjust the brightness of your screen using the Windows Control Panel. Simply hit the function button on the keyboard with the function key that corresponds to it. This key is generally placed between the Ctrl, Alt, and Windows/Start Menu keys, and it’s usually positioned just below the space bar. Look for the key labeled “fn” once you’ve identified the keys used to control the brightness.
