Features

Full 1920 x 1080 High-deﬁ nition Resolution Page 45

The LDT422V panel reproduces images from video and computer signals with precision and clarity, delivering full 1920 x 1080 highdeﬁ nition resolution. The high-durability panel reduces the risk of image persistence in commercial applications.

Wide-range Color Temperature Adjustment

The display color temperatures can be adjusted from 2,600 K to 10,000 K. Such a wide range adjustment is important for industries such as broadcasters and food retailers where color accuracy and ﬂ esh tones are critical.

Tiling Capability with Frame compensation

Up to 25 panels (5 wide x 5 high) can be combined to create a single large image (i.e., video wall) or other high-impact signage. A frame compesation function is incorporated to compensate the width of panel bezels so that images are displayed with the utmost accuracy.

PiP, PoP and Side-by-side

Picture-in-Picture and Picture-out-of-Picture are available when you want to display video content from a video input source in the sub picture and display the PC input source in the main picture, and vice versa. The native resolution as high as 1920 x 1080 can display these two input sources in the Side-by-side mode, ideal for broadcasting and video-conferencing applications.

Programmable Scheduling Function

The monitor’s operating schedule can be programmed for up to seven different scheduled time intervals by time, day of the week and input port. This allows video content from different inputs to be displayed on certain monitors within the same installation according to the schedule, and extends the monitor’s life and saves the power by turning it off during those hours or days it is not in use.

Screen-saver Functions

To reduce image persistence and maximize the panel life in demanding signage applications, the LDT Series is equipped with four screen-saver functions.

• GAMMA

• COOLING FAN

• BRIGHTNESS

• MOTION

Side Border Color Select

When the 4:3 screen is displayed, the side border color can be selected from black, gray and white.

Power-on Delay

For installations employing numerous monitors, the power-on delay function can power up the monitors sequentially with delay between 2-50 seconds after the power is applied. Using this function can prevent inrush current problems and reduce the overall electrical load requirements when a single power supply is used.

Flexible Landscape & Portrait Positioning

Designed to enhance for heat dissipation and long-term reliability in both landscape (horizontal) and portrait (vertical) positions.

Closed Caption

You can display captions. When closed-caption video signals are input, you can select to display or hide the captions on the screen. This monitor is compliant with EIA-608-A.

Troubleshooting

No picture

• The signal cable should be securely connected to the display card/computer.

• The display card should be securely seated in its slot.

• The Main Power Switch and the computer power switch should be in the ON position.

• Make sure that the correct mode has been selected on the display card or system being used. (Please consult the display card or system manual to change the graphics mode.)

• Check the monitor and your display card with respect to the compatibility and recommended settings.

• Check the signal cable connectors for bent or pushed-in pins.

Power button does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

Image persistence

• Please be aware that LCD Technology may experience a phenomenon known as “image persistence.” Image persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

NOTE:

As with all display devices, MITSUBISHI ELECTRIC recommends displaying moving images and using a moving screen saver at

regular intervals whenever the screen is idle or turning off the monitor when not in use.

Image is unstable, unfocused or swimming is apparent

• Signal cable should be securely attached to the computer.

• Use the OSD Image Adjust controls to focus and adjust the display by increasing or decreasing the ﬁ ne adjustment.

When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.

• Check the monitor and your display card with respect to the compatibility and recommended signal timings.

• If the displayed text is garbled, change the video mode to the non-interlace mode and use 60 Hz refresh rate.

Image of component signal is greenish

• Check to see if the DVD/HD input connector is selected.

LED on the monitor is not lit (No green or red color can be seen)

• Power Switch should be in the ON position and power cord should be connected.

• Make certain the computer is not in the power-saving mode (touch the keyboard or mouse).

RED LED on the monitor is blinking

• A certain failure may have occurred. Please contact your nearest authorized MITSUBISHI ELECTRIC service facility.

Displayed image is not sized properly

• Use the OSD Image Adjust controls to increase or decrease the coarse adjustment.

• Make sure that the correct mode has been selected on the display card or system being used.

(Please consult the display card or system manual to change the graphics mode.)

Selected resolution is not displayed properly

• Use OSD Display Mode to enter Information menu and check that the appropriate resolution has been selected. If not, select corresponding option.

No sound

• Check to see if the speaker cable is properly connected.

• Check to see if the mute is activated.

• Check to see if the volume is set to the minimum level.

Wireless remote control is not available

• Check the wireless remote control’s batteries status.

• Check if the batteries are inserted correctly.

• Check if the wireless remote control is pointing at the monitor’s remote sensor.

“SCHEDULE”/“OFF TIMER” function is not working properly

• The “SCHEDULE” function will be disabled when the “OFF TIMER” is set.

• If the “OFF TIMER” function is enabled and the power to the LCD monitor is turned off if the power supply is interrupted unexpectedly, then the “OFF TIMER” will be reset.

Either light vertical or horizontal stripes may appear, depending on the speciﬁ c display pattern. This is no product fault or degradation.
