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.
