The brightness and contrast control via the monitor menu is cumbersome. It's easier with our PC-WELT-Monitor-Brightness tool.

The monitor's brightness and contrast can only be set correctly for a certain ambient brightness. If there is more or less light in the room, you often have to readjust. This also applies to games that sometimes seem too dark. With notebooks, the brightness can be easily adjusted using a key combination. With desktop PCs, on the other hand, you have to use the rather cumbersome menu of the monitor if the manufacturer does not supply any software for the control.

In this case you can use our PC-WELT-Monitor-Brightness tool. It communicates with the monitor via DDC (Display Data Channel), which most current devices support. Sometimes there is also an option in the Monitor menu to enable DDC. If DDC is not available, PC-WELT-Monitor-Brightness cannot find the screen and the controls are not active.

Extract PC-WELT-Monitor-Brightness into any directory and start the program pcwMonitorHelligkeit.exe. You will then see a new icon in the notification area at the bottom right of the screen (see box “Customizing the notification area in the taskbar”). Click on it to open the window with the slide controls, in which you can set the brightness and contrast. If two monitors are connected to the PC, there are two pairs of controllers. If there are two identical devices, it is advisable to tick the checkboxes. This links the controllers and the settings affect both monitors at the same time.

Customize the notification area in the system tray

Programs that Windows starts automatically and that then run in the background must be able to make themselves felt somehow. The area in the taskbar is used for this, by default in the lower right corner of the screen next to the clock. Not all symbols are visible so that valuable space is not wasted. However, the small arrow on the left can be used to open a window that displays all the symbols. After clicking on "Customize" you can define the behavior.

Most programs have "Show notifications only" enabled. Message windows appear above the notification area when a program has something to tell you. You can also choose “Show icon and notifications”. Then the symbol is always visible in the notification area - useful for tools that display a status or that you want to reach quickly with a mouse click. The setting "Hide symbol and notifications" ensures that a program does not disturb you with the symbol or the message window.

The tool can also be conveniently controlled using the keyboard. Click on "Options> Settings", check the box in front of "Activate keyboard shortcuts" and press the desired keyboard shortcut in the respective fields. Only combinations with the Alt, Ctrl and Shift keys are possible.

Use the backspace or backspace key to remove a key combination. Only assign combinations that have not yet been used system-wide and are rarely used in programs.

If you want to use PC-WELT monitor brightness regularly, check the box in front of "Start with Windows" in the settings. The tool is then automatically available after Windows starts.

Use the command line: You will also find the pcwMonitorHelligkeit_CLI.exe tool in the “Console” subdirectory. You can use this to set brightness and contrast using a batch file or a script. The line

For example, for monitor 1 (“/ m: 1”) the brightness changes to “40” (“/ h: 40”) and the contrast to “30” (“/ k: 30”).

Adjust the monitor optimally: There are several ways to change the picture settings: either directly on the monitor, using software that controls the monitor, or using the graphics card driver. After installing a manufacturer driver, e.g. from Nvidia or AMD, you will usually be given additional setting options.

You can call up the Nvidia tool, for example, by clicking on a free area of ​​the desktop and selecting “Nvidia Control Panel” from the context menu. Under “Display> Adjust desktop color settings”, set the “Use Nvidia settings” option and adjust the brightness or contrast using the sliders.

Here you will also find the "Gamma" slider. The gamma correction takes the peculiarities of the human eye into account. The increase is exponential because the eye perceives changes in brightness in dark areas more strongly than in light areas. It therefore makes sense to set a pleasant basic brightness using "Brightness" and "Contrast" and then fine-tune it using the gamma controller. Under "Video> Adjust video color settings" you will find another set of controls that only affect the image of video content.

Incidentally, Windows comes with a tool that you can use to calibrate the monitor. Press Win + R, type dccw after “Open” and click “OK”. Before you get started, reset the monitor to factory settings via the device menu. Read through the instructions in the window, make the settings and click on “Next”.
