| 2. The message below appears. This message appears when the signal is not input correctly even when the monitor functions properly. | |
• This message appears when no signal is input. Example: ![]() | • The message shown left may appear, because some PCs do not output the signal soon after power-on.• Check whether the PC is turned on.• Check whether the signal cable is connected properly.• Switch the input signal with S.• When inputting a sync-on-green signal, the [SoG] setting for the monitor must be changed in advance (for analog signal). (page 10) |
• The message below shows that the input signal is out of the specified frequency range. (Such signal frequency is displayed in red.) Example: ![]() | • Check whether the signal setting of your PC matches the resolution and the vertical frequency settings for the monitor. (page 10)• Reboot the PC.• Select an appropriate display mode using the graphics board's utility software. Refer to the manual of the graphics board for details.fD : Dot Clock (Displayed only when the digital signal inputs)fH : Horizontal FrequencyfV : Vertical Frequency |

5-4 Glossary
Clock
The analog input monitor needs to reproduce a clock of the same frequency as the dot clock of the graphics system in use, when the analog input signal is converted to a digital signal for image display.
This is called clock adjustment. If the clock pulse is not set correctly, some vertical bars appear on the screen.
DDC/CI (Display Data Channel/Command Interface)
VESA provides the standardization for the interactive communication of the setting information, etc. between a PC and the monitor.
DVI (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct transmission of the PC's digital data without loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors. One is a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power-saving function. The “Monitor ON (operating mode)” and “Active Off (power-saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.
Gain
This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by the light passing through the panel color filter. Red, green and blue are the three primary colors. All the colors on the screen are displayed by combining these three colors. The color tone can be changed by adjusting the light intensity (volume) passing through each color's filter.
Phase
Phase means the sampling timing to convert the analog input signal to a digital signal. Phase adjustment is made to adjust the timing. It is recommended that phase adjustment be made after the clock is adjusted correctly.
Range Adjustment
Range adjustment controls the signal output levels to display every color gradation. It is recommended that range adjustment be made before color adjustment.
Resolution
The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. The display panel of this monitor consists of 1280 horizontal pixels and 1024 vertical pixels. At a resolution of 1280 x 1024, images are displayed as a full screen (1:1).
sRGB (Standard RGB)
International standard for “color reproduction and color space” among peripheral devices (such as monitors, printers, digital cameras, scanners). sRGB allows Internet users to closely match colors as a simple color matching means for the Internet use.
Sync-on-Green
A composite horizontal and vertical signal sync for the green signal in RGB. Typically, monitors use 5 signals, one for red, green and blue, and one for each horizontal and vertical sync. Sync-on-green monitors utilize three connections, one for red, one for blue and two synced horizontal and vertical signals that are counted as one green video signal.
Temperature
Color temperature is a method to measure the white color tone, generally indicated in degrees Kelvin. The screen becomes reddish at a low temperature, and bluish at a high temperature, like the flame temperature.
5000K: Slightly reddish white
6500K: Warm white like paper white
9300K: Slightly bluish white
TMDS (Transition Minimized Differential Signaling)
A signal transmission system for digital interface.
VESA DPMS (Video Electronics Standards Association - Display Power Management Signaling)
VESA provides the standardization of signals from PC (graphics board) for power saving of PC monitors. DPMS defines the signal status between PC and monitor.

Attention
- Display position may be deviated depending on the PC connected, which may require screen adjustment using Adjustment menu.
- If a signal other than those listed in the table is input, adjust the screen using the Adjustment menu. However, screen display may still be incorrect even after the adjustment.
- When interlace signals are used, the screen cannot be displayed correctly even after screen adjustment using the Adjustment menu.
