In the Windows settings you should be able to change the display of the graphic
Do you mean the calibration?
Select the Start button and then Settings> Ease of Use> High Contrast. To switch on the high contrast, select the toggle function under Switch on high contrast. Windows may display the "Please wait" screen for a few seconds.
To activate the increased contrast in Windows 10, simply hold down the left Alt key, the left Shift key and the top right button of the print key. Press the [Windows] and [R] keys simultaneously so that the "Execute" command opens
The brightness can typically be adjusted using function keys. A quick access for contrasts, saturation, gamma etc. Usually don't have notebooks.
Such fine adjustments are made via the driver software of the graphics card. Mostly this can be integrated directly into the right-click menu of the desktop or accessed via a taskbar icon.
What is the exact type designation of your laptop? I don't know of a laptop that doesn't have a function on a button.
Don't worry, I've tried all the buttons, there are no 😂
