Maintenance
- Clean the cabinet, panel and controls with a soft cloth lightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent, such as alcohol or benzine.
- Do not rub, touch, or tap the surface of the screen with sharp or abrasive items such as a ballpoint pen or screwdriver. This type of contact may result in a scratched picture tube.
- Clean the screen with a soft cloth. If you use a glass cleaning liquid, do not use any type of cleaner containing an anti-static solution or similar additive as this may scratch the screen's coating.
Transportation
When you transport this monitor for repair or shipment, use the original carton and packing materials.
Use of the Tilt-Swivel
With the tilt-swivel, this monitor can be adjusted to the desired angle within 180^ horizontally and 20^ vertically. To turn the monitor vertically and horizontally, hold it at the bottom with both hands as illustrated below.
Warning on power connection
- Use an appropriate power cord for your local power supply.
For the customers in the U.S.A.
If you do not use the appropriate cord, this monitor will not conform to mandatory FCC standards.
Examples of plug types
for 100 to 120 V AC
for 200 to 240 V AC
- Before disconnecting the power cord, wait at least 30 seconds after turning off the power to allow the static electricity on the CRT display surface to discharge.
After the power has been turned on, the CRT is demagnetized (degaussed) for about 3 seconds. This generates a strong magnetic field around the metal frame, which may affect the data stored on magnetic tapes and disks near the bezel. Place magnetic recording equipment, tapes and disks away from this monitor.
The outlet should be installed near the equipment and be easily accessible.

These operating instructions (1)
This monitor works with any IBM or compatible system equipped with VGA or greater graphics capability. Although this monitor works with other platforms running at horizontal frequencies between 30 and 94kHz (GDM-400PS), 30 and 107kHz (GDM-500PS), including Macintosh and Power Macintosh systems, a cable adapter is required. Please consult your dealer for advice on which adapter is suitable for your needs.
Step 1: Connect the monitor to the computer
With the computer switched off, connect the video signal cable to the monitor using the supplied HD15 video signal cable.
If you are using an IBM PC/AT or compatible computer, refer to the section below.
If you are using a Macintosh or compatible computer, refer to the following section, "Connecting to a Macintosh or compatible computer."
- If you want to use the 5 BNC connectors, refer to the section, "Connecting to the 5 BNC connectors."
Connecting to an IBM PC/AT or compatible computer
* The HD15 - HD15 adapter may be needed for some models.
If your PC system is not compatible with DDC2AB and DDC2B+
This monitor uses the No. 9 pin in the video signal connector for DDC2AB and DDC2B+ compatibility.
Some PC systems which are not compatible with either DDC2AB or DDC2B+ may not accept the No. 9 pin. If you are not sure whether your PC system accepts the No. 9 pin or not, use the HD15 (Female) - HD15 (Male without the No. 9 pin) adapter (not supplied). Make sure the male side (without the No. 9 pin) is connected to the computer.
Connecting to a Macintosh or compatible computer
About the supplied Macintosh adapter
The supplied Macintosh adapter is compatible with Macintosh LC, Performa, Quadra, Power Macintosh and Power Macintosh G3 series computers.
Macintosh II series and some older versions of Power Book models may need an adapter with micro switches (not supplied).
Connecting to the 5 BNC connectors
To connect the 5 BNC connectors, use the SMF-400 video signal cable (sold separately). Connect the cables from left to right in the following order: Red-Green-Blue-HD-VD.
Notes
- Do not short the pins of the video signal cable.
- The DDC standard does not apply to the 5 BNC connectors. If you use the DDC standard, connect the HD15 connector to the computer with the supplied video signal cable.
Step 2: Connect the power cord
With the monitor switched off, connect one end of the power cord to the monitor and the other end to a power outlet.
Step 3: Turn on the monitor and computer
The installation of your monitor is complete.
Note
If "OUT OF SCAN RANGE" or "NO INPUT SIGNAL" appears on the screen, see "Warning Messages" on page 20.
For customers using Windows 95/98
To maximize the potential of your monitor, install the new model information file from the supplied Windows Monitor Information Disk onto your PC.
This monitor complies with the "VESA DDC" Plug & Play standard. If your PC/graphics board complies with DDC, select "Plug & Play Monitor (VESA DDC)" or this monitor's model name as the monitor type in the "Control Panel" of Windows 95/98.
If your PC/graphics board has difficulty communicating with this monitor, load the Windows Monitor Information Disk and select this monitor's model name as the monitor type.
For customers using Windows NT4.0
Monitor setup in Windows NT4.0 is different from Windows 95/98 and does not involve the selection of monitor type. Refer to the Windows NT4.0 instruction manual for further details on adjusting the resolution, refresh rate, and number of colors.
Automatically Adjusting the Size and Centering of the Picture
By pressing the auto sizing and centering (ASC) button, the size and centering of the picture are automatically adjusted to fit the screen.
1 Turn on the monitor and computer.
2 Press the ASC button.
The picture is adjusted to fit the center of the screen.
Notes
- This function is intended for use with a computer running Windows or similar graphic user interface software that provides a full-screen picture. It may not work properly if the background color is dark or if the input picture does not fill the screen to the edges (such as an MS-DOS prompt).
- The screen may go blank for a few seconds while performing the auto-sizing function. This is not a malfunction.
- Although the signals for picture aspect ratio 5:4 (resolution: 1280 - 1024) do not fill the screen to the edges, the picture is accurately displayed.
Selecting the On-screen Display Language
If you need to change the OSD language, see "Using the LANG (Language) On-screen Display" on page 17. The default setting is English.
Selecting the Input Signal
This monitor has two signal input connectors (HD15 and 5BNC) and can be connected to two computers. When the power of both computers is on, select the input signal you want to view as follows.
1 Turn on the monitor and both computers.
2 Press the INPUT button to select the HD15 or 5BNC input signal.
Each time you press the INPUT button, the input signal and corresponding indicator alternate.
Selecting the INPUT signal mode
This monitor has two modes of input signal selection, "AUTO" and "MANUAL."
When "AUTO" is selected
If no signal is input from the selected connector, the monitor automatically selects the other connector's signal. When you restart the computer you want to view, or that computer is in power saving mode, the monitor may automatically select the other connector's signal. This is because the monitor switches from the interrupted signal to the constant signal. If this happens, manually select the desired signal using the INPUT button.
When "MANUAL" is selected
Even if no signal is input from the selected connector, the monitor does not select the other connector's signal.

Preset and User Modes
This monitor has factory preset modes for the most popular industry standards for true "plug and play" compatibility.
When a new input signal is entered, the monitor selects the appropriate factory preset mode and momentarily adjusts the phase calibration to provide a high quality picture to the center of the screen. The calibration is stored in memory and is immediately recalled whenever the same input signal is received.

For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor performs all of the adjustments necessary to ensure that a clear picture appears on the screen for any timing in the monitor's frequency range. However, it may be necessary to fine tune the vertical/horizontal size and centering. Simply press the ASC button or adjust the monitor according to the adjustment instructions. The adjustments are stored automatically as a user mode and recalled whenever the corresponding input signal is received.
Recommended horizontal and vertical timing conditions
Horizontal sync width duty should be: >4.8% of total horizontal time.
Horizontal blanking width should be: >2.5 sec.
Vertical blanking width should be: >450~ sec
Note for Windows users
For Windows users, check your video board manual or the utility program which comes with your graphic board and select the highest available refresh rate to maximize monitor performance.
Adjusting the monitor's resolution and color number
Adjust the monitor's resolution and color number by referring to your computer's instruction manual. The color number may vary according to your computer or video board. The color palette setting and the actual number of colors are as follows:
High Color (16 bit) 65,536 colors
True Color (24 bit) about 16.77 million colors
In true color mode (24 bit), speed may be slower.
Power Saving Function
This monitor meets the power-saving guidelines set by VESA and Energy Star, as well as the more stringent NUTEK.
If the monitor is connected to a computer or video graphics board that is VESA DPMS (Display Power Management Signaling) compliant, the monitor will automatically reduce power consumption in three stages as shown below.
You can set the delay time before the monitor enters the power saving mode using the OSD. Set the time according to "Setting the power saving delay time" on page 16.
Note
If no video signal is input to the monitor, the "NO INPUT SIGNAL" message (page 20) appears. After the delay time has passed, the power saving function automatically puts the monitor into the active-off mode and the indicator lights up orange. Once the horizontal and vertical sync signals are detected, the monitor automatically resumes its normal operation mode.
| Power consumption mode | Screen | Horizontal sync signal | Vertical sync signal | Power consumption | Recovery time | \( \widehat{\mathbf{O}} \) indicator | |

Damper Wires
When viewing a white background, very thin horizontal lines may be visible on the screen as shown below. These lines are the shadows of the damper wires and are characteristic of CRTs that use aperture grilles. The wires are attached to the aperture grille on the inside of the Trinitron tube and prevent the vibration of the aperture grille.
Damper wires
Plug & Play
This monitor complies with the DDC1, DDC2B, DDC2AB and DDC2B+ Display Data Channel (DDC) standards of VESA.
When a DDC1 host system is connected, the monitor synchronizes with the V. CLK in accordance with the VESA standards and outputs the EDID (Extended Display Identification Data) to the data line.
When a DDC2B, DDC2AB or DDC2B+ host system is connected, the monitor automatically switches to the appropriate standard.
DDCI is a trademark of the Video Electronics Standard Association.
Note
When using Windows 95/98, the DDC standard does not apply to the 5 BNC connectors. If you use the DDC standard, connect the HD15 connector to the computer with the supplied video signal cable.
Warning Messages
If there is something wrong with the input signal, one of the following messages appears.
The input signal condition
"OUT OF SCAN RANGE" indicates that the input signal is not supported by the monitor's specifications.
"NO INPUT SIGNAL" indicates that no signal is input, or the input signal from the selected input connector is not received.
The selected input connector
Indicates which input connector is receiving the wrong signal. If there is something wrong with the signal from both input connectors, "HD15" and "BNC" are displayed alternately.

| Picture is fuzzy | Adjust the contrast and brightness (page 9).Degauss the monitor (page 15).If you place equipment which generates a magnetic field, such as a loudspeaker, near the monitor, or you change the direction of the monitor, color may lose uniformity.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.If red or blue shadows appear along the edges of images, adjust the convergence (pages 13-14).If the moiré is cancelled, the picture may become fuzzy. Decrease the moiré cancellation effect (pages 13-14). |
| Picture bounces or has wavy oscillations | Isolate and eliminate any potential sources of electric or magnetic fields. Common causes for this symptom are electric fans, fluorescent lighting or laser printers.If you have another monitor close to this monitor, increase the distance between them to reduce the interference.Try plugging the monitor into a different AC outlet, preferably on a different circuit.Try the monitor on a different computer in a different room. |
| Picture is flickering | Set the refresh rate on the computer to obtain the best possible picture by referring to the computer's manual. |
| Picture appears to be ghosting | Eliminate the use of video cable extensions and/or video switch boxes if this symptom occurs. Excessive cable length or a weak connection can produce this symptom. |
| Wavy or elliptical (moire) pattern is visible | Cancel the moiré (pages 13-14).The moiré may be modified depending on the connected computer.Due to the relationship between resolution, monitor dot pitch and the pitch of some image patterns, certain screen backgrounds sometimes show moiré. Change your desktop pattern. |
| Two fine horizontal lines (wires) are visible | These wires stabilize the vertically striped aperture grille (page 19). This aperture grille allows more light to pass through to the screen giving the Trinitron CRT more color and brightness. |
| Hum is heard right after the power is turned on | When the power is turned on, the auto-degauss cycle is activated. While the auto-degauss cycle is activated (3 seconds), a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction. |
