HP 17" Color Monitor User's Guide Using Your Monitor Minimizing Eye Strain To avoid screen flicker and minimize eye strain, use the highest supported image refresh rate for the chosen resolution. It is recommended that you use a refresh rate of 85 Hz. The image refresh rate is the number of times per second that the image is refreshed. Minimizing Energy Consumption If your PC supports VESA monitor power management (available on many HP PCs), you can minimize the power consumed by the monitor. There are two power saving modes: • Suspend mode1 (uses less than 10 W). In this mode, the monitor's front panel indicator light blinks rapidly in green. • Sleep mode2 (uses less than 5 W). In this mode, the monitor's front panel indicator light blinks slowly in green. To set these power saving modes, refer to the manual that came with your PC. If your screen is not displaying an image, check the front panel indicator light first - your monitor may be in a power saving mode. 1. Suspend mode is activated when horizontal sync is cut by the video controller. 2. Sleep mode is activated when both vertical and horizontal sync are cut by the video controller. 10 English
