You might have to raise your chair so that your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you can lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that’s lower than the regular work surface.
Built-in Display
Adjust the angle of the display to optimize viewing in your environment. Do not force the display if you meet resistance. The display is not meant to open past 130 degrees.
You can adjust the brightness of the screen when you take the computer from one work location to another, or if the lighting in your work area changes.
