PIP/PBP
A detailed description of each function is provided. Refer to your product for details.
Chapter 05
―The functions available may vary depending on the product model. The color and shape of parts may differ
from what is shown. Specifications are subject to change without notice to improve quality.
PIP/PBP Mode
Enable or disable the PIP/PBP Mode function.
The PIP (Picture in Picture) function separates the screen into two parts. One source device is displayed
on the main screen at the same time the another source device is displayed in inset windows.
The PBP (Picture by Picture) function separates the screen in half displaying output from two different
source devices simultaneously on the left and right sides of the screen.
―PIP/PBP mode is compatible with Windows 7, Windows 8, and Windows 10.
―The PIP/PBP function may not be available depending on the specifications of the graphics card used. If the
screen is blank in PIP/PBP mode when the optimum resolution is selected, go to Control Panel → Display →
Screen Resolution and click Detect on the PC. (Instructions are based on Windows 7.)
―The screen may flicker briefly or appear after a delay when you enable or disable the PIP/PBP function or
when you change the screen size with the PIP/PBP function activated.
This can typically arise when a PC and a monitor are connected to two or more input sources. It has nothing to
do with the performance of a monitor.
The issue is mainly caused when the video signals are delayed in transmission to the monitor depending on
the graphics card performance.
―To maximize the picture quality, it is recommended to use a graphics card that supports WQHD+ (3440 x
1440) resolution.
―When using PIP/PBP, automatic switching to the optimum resolution and frequency is not available, due
to conformance with the graphics card and Windows. Set PIP/PBP Mode to Off. Alternatively, restart the
monitor, then set the resolution to the optimum setting using the Windows interface.
―If there are several inputs with different vertical frequencies when using PIP/PBP Mode, a lower vertical
frequency is applied.
For example, if input 1 is 50 Hz and input 2 is 100 Hz, the vertical frequency is set to 50 Hz.
With two 100 Hz input sources in PIP/PBP Mode, the vertical frequency maximum is 60 Hz.

―Horizontal Frequency
The time required to scan a single line from the left to the right side of the screen is called a horizontal cycle. The reciprocal number of a horizontal cycle is called horizontal frequency. Horizontal frequency is measured in kHz.
―Vertical Frequency
Repeating the same picture dozens of times per second allows you to view natural pictures. The repeat frequency is called "vertical frequency" or "refresh rate" and is indicated in Hz.
―This product can be set to only one resolution for each screen size to obtain the optimum picture quality due to the nature of the panel. Using a resolution other than the specified resolution may degrade the picture quality. To
