1. Precautions and Safety Notices
1. Please carefully read this manual before operating the device and keep it available for future reference.
2. To avoid the danger of the monitor falling and thereby possibly causing injury and/or serious damage to the monitor
itself, do not place it on unstable cars or desks. Be careful to avoid placing any stress on the LCD screen during
handling.
3. Do not place this monitor in areas that are wet or where water or other liquids may come in contact with it, such as
bathrooms, kitchens, wet floors, near washing machines or by swimming pools.
4. Remove the power plug from the electrical socket before cleaning. No water-containing cleaning agent should be
used to clean the screen, but only cleaning agents formulated specifically for cleaning LCD screens. Do not put any
liquid cleaning agent directly on the screen, but put it on a soft cloth first and then gently apply the cloth to the screen.
5. In order to guarantee reliable operation and adequate heat dissipation, do not cover or block vent holes on the monitor.
Do not put the monitor close to heat sources. Do not place the monitor on furniture such as a bookshelf, unless
sufficient ventilation is available.
6. A 3-pin grounding plug is provided for this monitor. In order to guarantee normal operation and safety of this unit,
this plug should be used with a matching grounded power socket.
7. Please follow all warnings and instructions that accompany the monitor.
8. Please pay special attention to power supply overloads, as electrical shock or fire may occur.
9. Do not place anything on the power cord. Do not hang the power cord over an area where people or objects may pass.
10. In case the monitor is not be used for an extended period, turn off power to avoid the possibility of short circuits
caused by lightning.
11. In order to avoid electrical shock or fire risks, do not insert any object through any openings in the monitor’s
enclosure. Do not allow any liquid to come in contact with the monitor.
12. In case of any abnormal noise or odor caused by incorrect operation, turn off power immediately and contact a
professional technician. Do not attempt to repair this monitor by yourself, as electrical shock may occur when
opening the back cover or accessing internal components.
13. If any of the following conditions occurs, turn off power and contact a repair service provider:
1) the power cord is damaged or worn;
2) liquid has gotten into the monitor, or the monitor has experienced immersion or wetting;
3) the monitor has fallen;
4) the monitor’s performance shows obvious changes;
5) the monitor fails to work normally when correct procedures are followed. In that case, please make any
adjustments in accordance with instructions supplied with the monitor; do not attempt any changes to
established procedures, as further damage may occur, making successful repair of the monitor more difficult.
14. In case parts need to be replaced, you must use identical parts or those supplied by our certified
manufacturers. Any other parts used without our authorization may result in electrical shock or
fire risk.

The following tips may help you optimize your display:
• Adjust the computer's graphics card so that it outputs a 1280 x 1024 @ 60Hz video signal to
the LCD display. (Look for instructions on “changing the refresh rate” in the graphics card's
user guide.)
• If necessary, make small adjustments using H. POSITION and V. POSITION until the
screen image is completely visible. (The black border around the edge of the screen should
barely touch the illuminated “active area” of the LCD display.)
The command line at the bottom of the
control screen tells what to do next from
this screen. You can toggle between control
screens, adjust the selected option, or exit
the screen.
VG730m-3_VA730m-1

Main Menu Controls
Adjust the menu items shown below by using the up Sand down Tbuttons.
Control Explanation
Auto Image Adjust sizes and centers the screen image automatically.
Contrast adjusts the difference between the image background (black level)
and the foreground (white level).
Brightness adjusts background black level of the screen image.
Input Select toggles between inputs if you have more than one computer
connected to the VG730m.
Audio Adjust
Volume increases the volume, decreases the volume, and mutes the audio.
Mute temporarily silences audio output.
Color Adjust provides several color adjustment modes, including preset color
temperatures and a User Color mode which allows independent adjustment of
red (R), green (G), and blue (B). The factory setting for this product is 6500K
(6500 Kelvin).
sRGB-This is quickly becoming the industry standard for color management,
with support being included in many of the latest applications. Enabling this
setting allows the LCD display to more accurately display colors the way they
were originally intended. Enabling the sRGB setting will cause the Contrast and
Brightness adjustments to be disabled.
9300K-Adds blue to the screen image for cooler white (used in most office
settings with fluorescent lighting).
7500K-Adds blue to the screen image for cooler white (used in most office
settings with fluorescent lighting).
6500K-Adds red to the screen image for warmer white and richer red.
5400K-Adds green to the screen image for a darker color.
