Video wall application.
Note:
♦
UHD resolution is supported only on video wall arrays. Each individual LCD display supports a max
resolution of 1080p.
General guidelines:
• The PC text quality is optimum in HD 1080 mode (1920 x 1080, 60Hz).
• Your PC display screen might appear different depending on the manufacturer (and your particular version
of Windows).
• Check your PC instruction book for information about connecting your PC to a display.
• If a vertical and horizontal frequency-select mode exists, select 60Hz (vertical) and 31.5KHz (horizontal). In
some cases, abnormal signals (such as stripes) might appear on the screen when the PC power is turned
off (or if the PC is disconnected). If so, press the [INPUT] button to enter the video mode. Also, make sure
that the PC is connected.
• When horizontal synchronous signals seem irregular in RGB mode, check PC power saving mode or cable
connections.
• The display settings table complies to the IBM/VESA standards, and based on the analog input.
• The DVI support mode is regarded as same to the PC support mode.
• The best timing for the vertical frequency to each mode is 60Hz.
6.4 Cleaning
Caution When Using the Display
• Do not bring your hands, face or objects close to the ventilation holes of the display. The top of the display
is usually very hot due to the high temperature of exhaust air being released through the ventilation holes.
Burns or personal injuries may occur if any body parts are brought too close. Placing any object near the
top of the display could also result in heat related damage to the object as well as the display itself.
• Be sure to disconnect all cables before moving the display. Moving the display with its cables attached may
damage the cables and thus cause fire or electric shock.
• Disconnect the power plug from the wall outlet as a safety precaution before carrying out any type of
cleaning or maintenance procedure.
Front Panel Cleaning Instructions
• The front of the display has been specially treated. Wipe the surface gently using only a cleaning cloth or a
soft, lint-free cloth.
• If the surface becomes dirty, soak a soft, lint-free cloth in a mild detergent solution. Wring the cloth to
remove excess liquid. Wipe the surface of the display to remove dirt. Then use a dry cloth of the same type
to dry.
• Do not scratch or hit the surface of the panel with fingers or hard objects of any kind.
• Do not use volatile substances such as insert sprays, solvents and thinners.
