HP ProDesk 490 G2 User Manual

High pitched noise coming from inside a flat panel monitor.
Cause Solution
Brightness and/or contrast settings are too high. Lower brightness and/or contrast settings.
Fuzzy focus; streaking, ghosting, or shadowing effects; horizontal scrolling lines; faint vertical bars; or unable to center the
picture on the screen (flat panel monitors using an analog VGA input connection only).
Cause Solution
Flat panel monitor’s internal digital conversion circuits may be
unable to correctly interpret the output synchronization of the
graphics card.
1. Select the monitor’s Auto-Adjustment option in the
monitor’s on-screen display menu.
2. Manually synchronize the Clock and Clock Phase on-screen
display functions. To download a SoftPaq that will assist
