Graphic Enhancement Mode
(GEM)
You can automatically change the characteristics of the picture
to match the way you use your monitor with the Graphic
Enhancement Mode (GEM). Simply press the
(GEM) button
to cycle through the three modes.
1
Turn on the monitor and computer.
2
Press the
(GEM) button to set the mode.
Each time you press the
(GEM) button, the mode changes
and appears on the screen as follows.
STANDARD MODE
PRESENTATION MODE
GRAPHICS/VIDEO MODE
The STANDARD MODE is ideal for spreadsheets, word
processing, and other text oriented applications.
The PRESENTATION MODE is useful for presentation
programs that require vivid colors.
The GRAPHICS/VIDEO MODE gives movies and games
enhanced visual appeal by increasing the sharpness and
brightness.
The selected mode indication appears on the screen for about
three seconds.
If the screen appears too white, adjust the color temperature
(see “Using the COLOR OSD” on page 7).
Note
The PRESENTATION MODE and GRAPHICS/VIDEO MODE may
produce ghost images when displaying text oriented applications.
These modes change the brightness of the picture dynamically
according to changes in moving pictures. If ghost images appear,
set the GEM to STANDARD MODE.

Warning Messages
If there is something wrong with the input signal, one of the following messages appears.
Input signal condition
• Make sure the power cord is properly connected.
• Make sure the
u
(POWER) switch is in the “ON” position.
• Try pressing any key on the computer keyboard.
• Make sure your computer is turned on.
• Make sure the video signal cable is properly connected and all plugs are firmly seated in
their sockets.
• Make sure none of the HD15 video input connector pins are bent or pushed in.
• Make sure the video board is completely seated in the proper bus slot.
• Make sure the video frequency range is within that specified for the monitor.
Horizontal: 30 – 70 kHz
Vertical: 50 – 120 Hz
Refer to your computer system’s instruction manual to adjust the video frequency range.
• If you are using a video signal cable adapter, make sure it is the correct type.
• Run the SELF TEST function:
1. Turn off the monitor and disconnect the video cable from the computer.
2. Turn on the monitor and wait five seconds. The “NO INPUT SIGNAL” message
should appear with a color bar pattern. The message and pattern are
displayed for 30 seconds.
If the monitor displays White, Red, Green and Blue colors, the monitor is
functioning properly.
• Make sure none of the HD15 video input connector pins are bent or pushed in.
• Check your video board manual for the proper monitor setting.
• Check this manual and make sure the monitor supports the graphics mode and the
frequency at which you are trying to operate. Even if the frequency is within the proper
range, some video boards may have a sync pulse that is too narrow for the monitor to
sync correctly.
• Degauss the monitor (page 8).
If you place equipment which generates a magnetic field, such as a loudspeaker, near the
monitor, or you change the direction of the monitor, the color may not be uniform.
The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field
for uniform color reproduction. If a second degauss cycle is needed, allow a minimum
interval of 20 minutes for the best result.
Additional Information
INFORMATION
OUT OF SCAN RANGE
The input signal condition
“OUT OF SCAN RANGE”
