How to adjust the viewing brightness
A free Office suite fully compatible with Microsoft Office
As most of the PDF files are reading materials, adjusting the brightness of the screen is needed. How can we do that?
1. Head to the Home tab, click the Background button.
2. Here, you can choose different viewing modes. If you find Default and Daytime are not suitable, you can choose Night Mode or Eye Protecting to reduce eye stress.This function can also be found in WPS Writer, WPS Spreadsheets and WPS Presentation.
