More and more users are using our computer during long daily sessions, which can be harmful to our eyes. To mitigate this visual fatigue a bit we can use a tool like Gammy, with which we can adapt the brightness of our computer screen depending on the lighting conditions, which will be of great help for those applications that are too bright during the day.
Gammy is ideal for controlling the brightness and color of the screen
The first thing to do is download Gammy for free from its website. The application is compatible with Windows 8.1 and Windows 10, as well as Linux. Once we execute it, in case of having high brightness we will notice how the screen dims automatically. The application stays hosted in the toolbar, where we can see its icon.
By double clicking on its icon, its main menu will appear, which we can use to set the maximum and minimum brightness levels. In this way the program will never increase the brightness too much nor will it dim it excessively. This configuration will be adapted to the different programs and screens that we use, so we will notice how the brightness rises or falls in each situation.
Brightness adjustment
If we remove the automatic brightness option, the application will give us the possibility to manually adjust both the screen brightness and the temperature, simply by dragging the corresponding bar. If we have the “Auto” option activated and we enlarge the panel a little from the bottom right, we can click on 3 horizontal points. Pressing will bring up some additional options. From here, we can control the adaptation speed , by means of which we will determine how fast the brightness changes. Through the threshold , it allows us to verify the differences in the content when applying the changes.
Temperature option
Under the brightness options, we find the temperature settings that we can use to define the color temperature levels. It has a maximum temperature of 6500K and the lowest of 2000K . If we click on the three vertical points, we can manually configure the temperature, establishing the maximum and minimum temperature in a time interval.
Contrary to what happens on the screen of mobile phones, computer screens do not include any type of sensor to automatically adjust the brightness of the screen. That is why Gammy is responsible for taking screenshots in a fraction of milliseconds and depending on the content that we are displaying and the colors that it reproduces will be in charge of adjusting the brightness of the screen.
