Troubleshooting
If you suspect something is not working correctly, you should :
1. Turn on the computer and monitor.
2. Set the brightness control to the proper position.
3. Ensure that all cables are securely connected.
4. Disable standby mode if it is enabled. Push the setup switch on the
back of the monitor to determine whether standby mode is enabled.
5. Disable the computer's screen saver program if it is enabled.
6. Run the auto setup procedure described in

Configuring your Monitor

on page 8
7. If there is screen noise, adjust the PHASE parameter in the
Intermediate Controls
on page 32.
8. Adjust the CLOCK parameter in the
Intermediate Controls
on page 32
to suppress the display of vertical stripes.
9. If you are using an RS/6000 with composite output function, do not
specify ‘DPMS’ to the STANDBY parameter in the

Basic Controls

on
page 31.
10. To restore all the auto setup settings to the original values in effect when
the monitor was shipped, perform SYSTEM RESET in the

Intermediate

Controls

on page 32, or press each minus button of the brightness and
the contrast control simultaneously and turn on the monitor. Both LED
indicators turn on and off, and all settings are restored.
11. Set the screen mode to the

Supported Screen Addressability

in the
table on page 38.
12. Perform AUTO SETUP for each display mode (each screen resolution).
13. On this monitor, different from a CRT, faster refresh rate does not make
the screen quality better. Using the monitor with a refresh rate of 60 Hz
with noninterlace is recommended.
The LCD contains over
3,900,000 thin-film
transistors (TFTs). A small
number of missing, discolored, or
lighted dots may be present on
the screen, which is an intrinsic
characteristic of the TFT LCD
technology and is not an LCD
defect.
