Frequently Asked Questions
General
Monitors
What is plug and play and what does it do?
The plug and play function allows the monitor to inform the host system of its identity and, depending on the level of DDC used, communicate additional information about its display capabilities. The monitors will appear to be non functional if there is no video input signal. In order for the monitor to work properly, there must be a video input signal.
Power LED Is Not ON
Make sure the power button is ON and the Power Cord is properly connected to a grounded power outlet and to the monitor.
Picture Is Fuzzy & Has Ghosting Shadowing Problem
Adjust the Contrast and Brightness Controls. Press to auto adjust. Make sure you are not using an extension cable or switch box. We recommend plugging the monitor directly to the video card output connector on the back.
Picture Bounces, Flickers Or Wave Pattern Appears In The Picture
Move electrical devices that may cause electrical interference as far away from the monitor as possible. Use the maximum refresh rate your monitor is capable of at the resolution your are using.
Do you have drivers for the Mac?
To use your monitor with Mac, you will need to install the Plug and Play driver that is offered by your Mac operating system. For information on how to install the Plug and Play driver on your Mac operating system, please contact Mac technical support.

Why is the display of my monitor fuzzy and it has ghosting & shadowing problem?
These problems are caused by using an extension video cable or switch box.

Also make sure that all the pins of the monitor's video cable are in good condition.
Why do I see horizontal & vertical disturbances or waving on the screen?
Use the Windows Shut Down screen and activate the AUTO-ADJUST feature of your monitor. You can display the Windows Shut Down screen by pressing START & then Shut Down. Refer to the monitor's documentation for instructions on how to activate the AUTO-ADJUST feature.
Why is the display of my monitor blurred or unfocused?
Make sure the PC is set to run the monitor at its true or native resolution. The native and recommended resolution depends on the size of the monitor. All models can typically be set to 60Hz or 75Hz, with resolutions as follows. 15" LCD: 1024 x 768. 17" or 19" LCD: 1280 x 1024. 19" widescreen: 1440 x 900. 20" to 22" widescreen: 1680 x 1050. 24" widescreen: 1920 x 1200. Please check the user manual and/or specifications for your model. You can adjust the resolution in Display Properties located in the Windows Control Panel (in Windows Vista, select the Personalisation feature).

Disconnect the power cord first. Spray or put on a small amount of non-abrasive cleanser on a soft lint free cloth. Gently wipe the surface without too much pressure as the screen is fragile.
