G54-6546 / G74-6547 Display



G54-6546 / G74-6547 - Display modes

The display mode the monitor uses is controlled by the computer. Therefore, you should refer to your computer documentation for details on how to change display modes.

The image size, position and shape may change when the display mode changes. This is normal and the image can be readjusted using the monitor controls.

To ensure flicker­free operation, select the highest (non­interlaced) refresh rate both the computer and the monitor can support, (generally 72 Hz or higher), for the addressability that your application requires.

For the display modes listed below, the screen image has been optimized during manufacture.

Factory Set Display Modes.

Power Management

To benefit from power management, the monitor must be used in conjunction with a computer that implements the Video Electronics Standards Association (VESA) Display Power Management Signalling (DPMS) Standard.

The power management feature is invoked when the computer recognizes that you have not used your mouse or keyboard for a user­definable period of time. There are several states as described in the table below.

Energy savings in the Stand-by and Suspend states meet the ENERGY STAR  power consumption requirements. As an ENERGY STAR  Partner, IBM has determined that this product meets the ENERGY STAR  guidelines for energy efficiency.

Troubleshooting

If you have a problem setting up or using your monitor, you may be able to solve it. try the suggested actions that are appropriate to your problem.


Problem Possible Cause - Suggested Action Reference

Screen is blank and
power indicator is
off.
No power to monitor. Ensure that the electrical outlet and
the monitor are both switched on.
Check that the power cord is firmly
plugged into the monitor and the
electrical outlet.
If the power cord plug has a
removable fuse, replace it.
Try another power cord.
Try another electrical outlet.
Screen is blank and
power indicator is
steady green.
Brightness and
Contrast may be too
low.
Adjust brightness and contrast.
Screen is blank and
power indicator is
flashing green
every half second.
The monitor is in
the Power Management
Standby state.
--------------------
Display mode of the
computer is outside
the range of the
monitor.
Press any key on the keyboard or move
the mouse to restore operation.
Check the Power Management software on
your computer.
----------------------------------------
Reconfigure the computer to use a
supported display mode.
Screen is blank and
power indicator is
flashing green
every 1 or 2
seconds.
The monitor is in the
Power Management
Suspend or Off state.
Press any key on the keyboard or move
the mouse to restore operation.
Check the Power Management software on
your computer.
'Check Signal Cable'
displays on the
screen.
The monitor is not
receiving a video
signal.
Check that the signal cable is firmly
connected to the computer and monitor.
Check that no pins are bent in the
signal cable connector.
Image appears to
be flickering.
The monitor is
operating in an
interlaced or low
refresh rate display
mode.
--------------------
The monitor may be
affected by
interference from
nearby equipment.
Reconfigure the computer to use a non-
interlaced display mode with a refresh
rate of at least 75 Hz.
----------------------------------------
Move fluorescent desk lighting or any
equipment that produces magnetic fields
further away from the monitor.
Image appears to
be discoloured.
The monitor may be
affected by
interference from
nearby equipment.
--------------------
Magnetization of
monitor components
has built up.
--------------------
Move any equipment that produces magnetic
magnetic fields (e.g. sub woofer loud
speakers) further away from the monitor.
If another monitor is close by, a
separation distance of at least 6 inches
(150 mm) is recommended.
----------------------------------------
Degauss the monitor.
----------------------------------------
Adjust the Color settings.
