HP Z1 Maintenance And Service Guide

Table 4-4 External display problems (continued)
Problem Cause Solution
Fuzzy focus; streaking,
ghosting, or shadowing
effects; horizontal
scrolling lines; faint
vertical bars; unable to
center the picture on
the screen (flat-panel
monitors using an
analog VGA input
connection only.)
Flat-panel monitor’s internal
digital conversion circuits might
be unable to correctly interpret
the output synchronization of the
graphics card.
1. Select the monitor’s Auto-Adjustment option in the
monitor’s onscreen display menu.
2. Manually synchronize the Clock and Clock Phase
onscreen display functions.
Some typed symbols do
not appear correctly.
The font you are using does not
support that symbol.
Use the Character Map to locate and select the appropriate
symbol.
Select Start > All Programs > Accessories >
System Tools > Character Map. You can copy the
symbol from the Character Map into a document.
The graphics driver does is not
working properly or does not
support the symbol set with that
resolution.
Try either solution:
●
Change the panel resolution in the Windows Control
Panel > Screen Resolution menu or through the
control panel for the graphics controller (Intel or
nVidia).
●
Install the latest graphics driver:
1. Boot into the OS and uninstall the graphics driver.
2. Restart the computer.
3. Install the latest graphics driver for your graphics
controller.
