Handling The Screen; On Burn-In; On A Long Period Of Use; Handling And Maintenance Of The Screen - Sony BVM-E250 Operation Manual

Handling the Screen

• The 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 panel, 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 for its high-precision images, permanent burn-in may
occur if still images are displayed in the same position on
the screen continuously, or repeatedly over extended
periods.
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 viewfinder 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.

Precautions

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.
Handling and Maintenance of the
Screen
The surface of the screen is specially coated to reduce
image reflection. Make sure to observe the following
points as improper maintenance procedures may impair the
screen's performance. In addition, the screen is vulnerable
to damage. Do not scratch or knock against it using a hard
object.
• Be sure to disconnect the AC power cord from the AC
outlet before performing maintenance.
• The surface of the screen is specially coated. Do not
attach adhesive objects, such as stickers, on it.
• The surface of the screen is specially coated. Do not
touch the screen directly.
• Wipe the screen surface gently with the supplied
cleaning cloth or a soft dry cloth to remove dirt.
• Stubborn stains may be removed with the supplied
cleaning cloth, or a soft cloth slightly dampened with a
mild detergent solution.
• The screen may become scratched if the cleaning cloth is
dusty.
• Never use strong solvents such as alcohol, benzene,
thinner, acidic or alkaline detergent, detergent with
abrasives, or chemical wipe as these may damage the
screen.
• Use a blower to remove dust from the screen surface.
