• Check that the monitor is correctly connected to the computer.
• If NO INPUT SIGNAL appears on the screen, confirm that 

your computer’s graphic board is completely seated in the 
correct bus slot. 

• If you are replacing an old monitor with this model and OUT 

OF SCAN RANGE appears on the screen, reconnect the old 
monitor. Then adjust the computer’s graphic board so that the 
horizontal frequency is between 30 – 70 kHz, and the vertical 
frequency is between 48 – 120 Hz.

For more information about the on-screen messages, see “Trouble 
symptoms and remedies” on page 14.

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.

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.

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) 

t 65,536 colors

• True Color (24 bit) 

t about 16.77 million colors

In true color mode (24 bit), speed may be slower.

Your monitor has one upstream USB connector (on the rear 
panel) and four downstream USB connectors (two on both the left 
and right sides). They provide a fast and easy way to connect USB 
compliant peripheral devices (such as keyboards, mice, printers 
and scanners) to your computer using a standardized USB cable.
To use your monitor as a hub for your peripheral devices, connect 
the USBs as illustrated below.

If a message appears on your screen, follow the on-screen instructions 
and select Generic USB Hub as the default setting.

• Not all computers and/or operating systems support USB 

configurations. Check your computer’s instruction manual to see if you 
can connect USB devices.

• In most cases, USB driver software needs to be installed on the host 

computer. Refer to the peripheral device’s instruction manual for 
further details.

• The monitor functions as a USB hub as long as the monitor is either 

“on” or in power saving mode.

• If you connect a keyboard or mouse to the USB connectors and then 

boot your computer for the first time, the peripheral devices may not 
function. First connect the keyboard and mouse directly to the 
computer and set up the USB compliant devices. Then connect them to 
this monitor.

• Do not lean on the monitor when plugging in the USB cables. The 

monitor may suddenly shift and cause injury.
