Use Night Light; Use The Multi-Touch Screen (For Selected Models) - Lenovo ThinkCentre M90a User Manual

Use Night light

Blue light is the high-energy visible light in the light spectrum. Excessive exposure to blue light might damage
your vision. Night light is a feature that reduces the blue light emitted by computer displays. When the night
light is on, your computer display shows warmer colors that help you reduce eye strain.
To turn on or turn off the night light, do one of the following:
• Type Night light in the search box. Click Night light to open its settings window. Then, follow the on-
screen instructions.
• Open the Start menu. Click Settings ➙ System ➙ Display. Then, turn on or turn off the Night light
switch.

Use the multi-touch screen (for selected models)

If your computer display supports the multi-touch function, you can navigate the screen with simple touch
gestures.
Note: Some gestures might not be available depending on the app you use.
