Justér kontrasten
You can adjust the contrast of windows and buttons so that they’re easier to see. This is not the same as changing the brightness of the whole screen; only parts of the user interface will change.
Go to the Desktop and start typing Accessibility.
Click on Accessibility to open the panel.
Tænd for Høj kontrast-kontakten i afsnittet Syn.
Slå høj kontrast til og fra, hurtigt
You can turn high contrast on and off by clicking the accessibility icon on the taskbar and selecting High Contrast.
