assistance, see Chapter 11 "Getting information, help, and service" on page 121.

The image appears to be flickering

Solutions:

• The screen might be affected by interference from nearby equipment. Magnetic fields around other

devices, such as transformers, appliances, fluorescent lights, and other monitors might be causing the

problem. Move fluorescent desk lighting or any equipment that produces magnetic fields farther away

from the screen. If this does not correct the problem, turn off the computer. Then, adjust the placement of

the computer and other devices so that they are at least 305 mm (12 inches) apart. Turn on the computer.

• Reset the refresh rate supported by your computer.

1. Right-click a blank area on the desktop.

2. Depending on your Windows version, do one of the following:

– For Windows 7, Windows 8, or Windows 8.1: Click Screen resolution ➙ Advanced settings.

– For Windows 10: Click Display settings. On the Display tab, click Advanced display settings ➙

Display adapter properties.

3. Click the Monitor tab, and then reset the refresh rate to be the highest and noninterlaced.
