Handling The Screen; On A Long Period Of Use - Sony TRIMASTER EL PVM-A250 Manual

Precaution
On Safety
 Operate the unit only with a power source as specified
in the "Specifications" section.
A nameplate indicating operating voltage, etc., is

located on the rear panel.
 Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it any further.
Do not drop or place heavy objects on the power cord.

If the power cord is damaged, turn off the power
immediately. It is dangerous to use the unit with a
damaged power cord.
 Unplug the unit from the wall outlet if it is not to be
used for several days or more.
Disconnect the power cord from the AC outlet by

grasping the plug, not by pulling the cord.
The socket-outlet shall be installed near the

equipment and shall be easily accessible.
On Installation
Allow adequate air circulation to prevent internal heat

build-up.
Do not place the unit on surfaces (rugs, blankets, etc.)
or near materials (curtains, draperies) that may block
the ventilation holes.
Do not install the unit in a location near heat sources

such as radiators or air ducts, or in a place subject to
direct sunlight, excessive dust, mechanical vibration or
shock.

Handling the Screen

The OLED panel fitted to this unit is manufactured

with high precision technology, giving a functioning
pixel ratio of at least 99.99%. Thus a very small
proportion of pixels may be "stuck", either always off
(black), always on (red, green, or blue), or flashing. In
addition, over a long period of use, because of the
physical characteristics of the organic light-emitting
diode, such "stuck" pixels may appear spontaneously.
These problems are not a malfunction.
 Do not leave the screen facing the sun as it can damage
the screen. Take care when you place the unit by a
window.
Do not push or scratch the monitor's screen. Do not

place a heavy object on the monitor's screen. This may
cause the screen to lose uniformity.
 The screen and the cabinet become warm during
operation. This is not a malfunction.
On Burn-in
Due to the characteristics of the material used in the
OLED panel, permanent burn-in or reduction in
brightness may occur.
These problems are not a malfunction.
Images that may cause burn-in
 Masked images with aspect ratios other than 16:9
Color bars or images that remain static for a long time

Character or message displays that indicate settings or

the operating state
 On-screen displays such as center markers or area
markers
To reduce the risk of burn-in
Turn off the character and marker displays

Press the MENU button to turn off the character
displays. To turn off the character or marker displays
of the connected equipment, operate the connected
equipment accordingly. For details, refer to the
operation manual of the connected equipment.
 Turn off the power when not in use
Turn off the power if the monitor is not to be used for
a prolonged period of time.
Screen saver
This product has a built-in screen saver function to
reduce burn-in. When an almost still image is displayed
for more than 10 minutes, the screen saver starts
automatically and the brightness of the screen decreases.

On a Long Period of Use

Due to an OLED's panel structure and characteristics of
materials in its design, displaying static images for
extended periods, or using the unit repeatedly in a high
temperature/high humidity environments may cause
image smearing, burn-in, areas of which brightness is
permanently changed, lines, or a decrease in overall
brightness.
In particular, continued display of an image smaller than
the monitor screen, such as in a different aspect ratio,
may shorten the life of the unit.
Avoid displaying a still image for an extended period, or
using the unit repeatedly in a high temperature/high
humidity environment such an airtight room, or around
the outlet of an air conditioner.
To prevent any of the above issues, we recommend
reducing brightness slightly, and to turn off the power
whenever the unit is not in use.
