TCO Information
Congratulations!
This display is designed for both you and the planet!
The display you have just purchased carries the TCO Certified
label. This ensures that your display is designed, manufactured
and tested according to some of the strictest quality and
environmental requirements in the world. This makes for a high
performance product, designed with the user in focus that also
minimizes the impact on the climate and our natural
environment.
TCO Certified is a third party verified program, where every product model is tested by an
accredited impartial test laboratory. TCO Certified represents one of the toughest certifications
for displays worldwide.
Some of the Usability features of the TCO Certified for displays:
• Good visual ergonomics and image quality is tested to ensure top performance and reduce
sight and strain problems. Important parameters are luminance, contrast, resolution, black
level, gamma curve, color and luminance uniformity, color rendition and image stability.
• Product have been tested according to rigorous safety standards at an impartial laboratory.
• Electric and magnetic fields emissions as low as normal household background levels.
• Low acoustic noise emissions.
Some of the Environmental features of the TCO Certified for displays:
• The brand owner demonstrates corporate social responsibility and has a certified
environmental management system (EMAS or ISO 14001).
• Very low energy consumption both in on- and standby mode minimize climate impact.
• Restrictions on chlorinated and brominated flame retardants, plasticizers, plastics and heavy
metals such as cadmium, mercury and lead (RoHS compliance).
• Both product and product packaging is prepared for recycling.
• The brand owner offers take-back options.
The requirements can be downloaded from our web site. The requirements included in this
label have been developed by TCO Development in co-operation with scientists, experts, users
as well as manufacturers all over the world. Since the end of the 1980s TCO has been involved
in influencing the development of IT equipment in a more user-friendly direction.
Our labeling system started with displays in 1992 and is now requested by users and
ITmanufacturers all over the world. About 50% of all displays worldwide are TCO certified.
For displays with glossy bezels the user should consider the placement of the display as
the bezel may cause disturbing reflections from surrounding light and bright surfaces.

Using the LCD Display
Setting the Timing Mode
Setting the timing mode is important for maximizing the quality of the screen image and
minimizing eye strain. The timing mode consists of the resolution (example 1920 x 1080) and
refresh rate (or vertical frequency; example 60 Hz). After setting the timing mode, use the
OSD (On-screen Display) controls to adjust the screen image.
For the best picture quality set your LCD display timing mode to:
VESA 1920 x 1080 @ 60Hz.
To set the Timing Mode:
1. Set the resolution: Right-click on the Windows desktop > Properties > Settings > set the
resolution.
2. Set the refresh rate: See your graphic card's user guide for instructions.
WARNING: Do not set the graphics card in your computer to exceed the maximum refresh
rate of 75Hz; doing so may result in permanent damage to your LCD display.
OSD and Power Lock Settings
•OSD Lock: Press and hold [1] and the up arrow for 10 seconds. If any buttons are
pressed the message OSD Locked will display for 3 seconds.

Troubleshooting
No power
• Make sure power button (or switch) is ON.
• Make sure A/C power cord is securely connected to the LCD display.
• Plug another electrical device (like a radio) into the power outlet to verify that the outlet is
supplying proper voltage.
Power is ON but no screen image
• Make sure the video cable supplied with the LCD display is tightly secured to the video
output port on the back of the computer. If the other end of the video cable is not attached
permanently to the LCD display, tightly secure it to the LCD display.
• Adjust brightness and contrast.
• If you are using an Macintosh older than G3, you need a Macintosh adapter.
Wrong or abnormal colors
• If any colors (red, green, or blue) are missing, check the video cable to make sure it is
securely connected. Loose or broken pins in the cable connector could cause an improper
connection.
• Connect the LCD display to another computer.
• If you have an older graphics card, contact ViewSonic®for a non-DDC adapter.
Control buttons do not work
• Press only one button at a time.
