TIPS

Using a wide-screen monitor

  • This monitor has a screen mode selection feature. If an incompatible screen mode is selected to play certain software, such as a TV program, the image would appear different from the original. Take this into consideration when making screen mode choices.
  • Use of this monitor in its enlarged display mode with the wide feature enabled in coffee shops, hotels and other establishments for commercial or pubic viewing purposes could infringe on the copyright holder's right protected by Copyright Law.
  • When a normal 4:3 image is displayed over the entire screen in the PANORAMA mode, not the Wide mode, parts of the periphery of the image may disappear and/or appear distorted in some cases. Use the 4:3 mode to view images, which were created in 4:3 mode. This mode allows 4:3 content to be viewed without picture distortion.

IMAGE RETENTION OF PLASMA DISPLAY

There are different characteristics that result in panel image retention depending on how the plasma display is used. Situations and effective usage methods related to ghosting are provided below.

Image retention characteristics of a plasma display

The image retention phenomenon of a plasma panel occurs due to partial phosphor degradation arising from partial character and figure display.

For example, when the character image as shown in Fig. A at the right is continuously displayed for a long period of time, the only part of the phosphor (Red, Green, Blue) that will degrade will be the color of the applicable character display portion. Consequently, when a while image is displayed on the entire screen as shown in Fig. a, the character marks displayed up to that time will become a color difference visible to the eye, but the phosphor will never burn.

HITACHI CMP4121HDU - Image retention characteristics of a plasma display - 1

■The degree of image retention is proportional to the brightness of the characters and figures displayed as well as the display time.

- The tendency of the phosphor is to degrade more the brighter the characters and figures are displayed. When images of figures with different levels of brightness, as shown in Fig. B, are continuously displayed for a long period of time, it becomes easier for image marks at locations when the brighter figures are displayed to be noticeable.

【Fig. b】

* The image retention images in this document are exaggerated for the purpose of explanation. The actual manner in which the image retention is seen differs depending on the operation time and brightness.

Methods to Reduce the Occurrence of Image Retention

- Lower the CONTRAST and BRIGHTNESS settings of the plasma display as much as possible.

A function is provided in the display that controls the brightness of the screen to reduce degradation of the panel. Using this function makes it possible to reduce image retention.

(Refer to OPERATE MODE (LIFE EXTEN. 1 OR LIFE EXTEN. 2 shown on 18)

- Set the plasma monitor to an "INVERSE" or "WHITE" display.

The occurrence of image retention when displaying images of identical patterns, such as static images, for long periods of time can be reduced by displaying a reversed color or completely white screen for about 1 \~ 2 hours after terminating the display. (Settings can be made using INVERSE AND WHITE of OTHER MENU shown on [23])

• Using in combination with moving images

Since the degradation of the fluorescent material progresses comparatively uniform for moving images, the occurrence of partial image retention can be controlled. We recommend to use in combination with moving images such as a DVD.

* Please be careful since image retention will occur if display is left in a two screen display state for a long period of time.

* Television broadcasts include images displayed for long periods of time in which the left and right or top and bottom of the image are cut and broadcast station name or time are displayed for a long period of time at the same portion of the screen. Image retention in these portions can be expected to occur, so please be aware.

NOTES

About screen defects

- High precision technology is used in the making of plasma panels but there may be dark spots (points that do not illuminate) and bright spots (points that are too bright) in some cases. These do not indicate a malfunction.

About residual images

- In some cases, residual images may remain after the short-term display of still images and another image is displayed, but these will disappear and return to normalcy. This is not a malfunction.

About the panel screen

- Plasma displays display images by means of electrical discharges inside the panel. Because of this, the temperature of the panel surface may rise in some cases. Also, plasma displays are made of finely processed glass. A reinforced glass filter is installed over the panel surface but avoid strong impact because there is still danger of glass breakage.

Symptoms That Seemingly Appear to be Failures

Make the checks suggested below depending on the symptoms observed. If the symptoms remain uncorrected, contact your dealer.

The screen becomes dark and the images cannot be seen during VTR special playback (fast forward, rewind).This sometimes occurs when a component output VTR such as the 480i is connected.This is not a malfunction; therefore, please take note that this may occur. When it does occur, change to composite output, or S1 (or S2) output.-
The display image does not come out by the SCART signal.Check the way the signal cable is connected.Check the setup.1222
The temperature of the display panel surface is high.The plasma display panel is lighting the phosphors by the discharge of internal radiation. In some cases, this may cause the temperature of the panel surface to increase. Please note that this is not a malfunction.-
There are locations on the screen that are different from the periphery (*).*Points that do not light, points with brightness different from that of the periphery, points with color different from that of the periphery, etc.High-precision technology is used to manufacture the plasma display panel, However in some cases, there are minor defects in some parts of the screen. Please note that this is not a malfunction.-
Vertical stripes appear, depending on the screen contents.The plasma display panel is lighting the phosphors by the discharge of internal radiation. Depending on the screen contents, in rare cases this may cause vertical stripes to appear because of failure to light. Please note that this is not a malfunction.-
Coarse horizontal stripes appear in FULL display.Adjusting the phase will reduce the horizontal stripes.(RGB input)-
The display dims to make the picture invisible during special playback of a VCR (FF, REW).This condition may occur when the unit is connected to a VCR with component output, such as 480i, but it is not a failure. But when it occurs, switch to composite output or S1 (S2) output).-
Flickering in the form of horizontal lines oscillating up and down.(PC INPUT MODE only)If the direct frequency from the computer is below 85Hz, try a higher frequency (upper limit 85Hz). There may be a slight attenuation of the current image.Try turning the FILTER ON. For this case however, the vertical resolution will drop.18
The fan motor is noisy.Use the fan that controls the temperature in the main body to lower the temperature of this unit. If the ambient air temperature increases, the fan will start, the RPMs will increase and motor noise will grow louder. This is not a malfunction though.-
The top of the monitor heats up.When used for long periods of time, the top of the monitor may heat up. This is not a malfunction.-
Text characters are displayed with varying thicknesses.The thicknesses of characters and lines may vary if images with a vertical resolution greater than 512 lines are displayed; however, this is not a malfunction.-
