■TWO WINDOW function
The “TWO WINDOW” function displays two inputs selected from VIDEO, SDI1/2, YP
BPR/RGB or DVI-D in two
windows.
Each press of the button ([FUNCTION1] to [FUNCTION5]) (page 32) to which the TWO WINDOW function has
been assigned changes the display mode.
(In the factory default setting, it is assigned to FUNCTION3.)
Note:
 When the main window and sub-window input setting is “YP
BPR/RGB” and “RGB-COMP,” the main window
and sub-window are displayed in a single window. When the input settings for the main window and sub-
window are both “DVI-COMP,” they are also displayed in a single window.
 When the input signals selected in the main and sub-window differ, the color shade, etc. may differ slightly.
 When the input signal terminals of video displayed in the main window and sub-window differ, the still image
function does not work. 
 The main window is normally displayed on the left side.
 When SDI1 or SDI2 is selected for the main window and sub-window, both windows will show the same
screen.

■TWO WINDOW screen sync
In single screen display, the TWO WINDOW screen is synchronized to the frame rate frequency of the input signal
format. 
In split screen display, the screen used as a reference for synchronization changes with the input signal format and
“TWO WINDOW SIZE” settings as shown in the following table.
Screen synchronization and display in split-screen mode
 No screen is displayed when the screen is not synchronized to the reference sync or the reference sync is not input or is in an incompatible format.
 When the frame frequency of the input signal formats of the main window and sub-window differ, frames may be skipped in the screen that is not synchronized to the reference sync.

REMOTE Specifications
 This monitor permits remote operation via GPI/RS-232C terminal. 
GPI screen items correspond to the following terminals. Use the GPI menu to assign functions to each terminal (J page 35). 
Functions assigned to terminals are executed when GND (pin 5) is shor t-circuited (ON) or open (OFF). 
■Operating conditions
Level operation: Operates when GND is short-circuited. 
Edge operation: Operates when GND changes from
open to short-circuited. 
 When level operation is assigned to more than one terminal, the function operates as long as one of
the terminals is short-circuited.
Edge operation should hold for 0.2 s or more after a
change. 
*1 When a 16:9 marker and a 4:3 marker are simultaneously selected and activated on a 16:9 aspect ratio display, both markers are displayed. 
*2 When a 16:9 marker and a 4:3 marker are simultaneously displayed, the background of the marker selected by the 16:9 marker is controlled. 
*3 When “R-TALLY” and “G-TALLY” simultaneously go on, the tally color changes to orange.

■Priority of assigned functions
 When both “MARKER1” and “MARKER2” are activated at the same time, “MARKER1” has priority. However, when the display aspect ratio is 4:3, the “MARKER1” aspect ratio is 16:9 and the “MARKER2” aspect ratio is 4:3,
“MARKER2” is displayed. In this case, the “MARKER2” background is controlled. 
 When “MARKER BACK HALF” and “MARKER BACK BLACK” are activated at the same time, “MARKER BACK BLACK” has priority. 
 During GPI edge operation and two or more of “INPUT SEL. VIDEO”, “INPUT SEL. SDI1”, “INPUT SEL. SDI2”, “INPUT SEL. YP
BPR/RGB” and “INPUT SEL. DVI-D” are simultaneously activated, priority goes to the last
activated item. During level operation, priority is assigned in the following order: “INPUT SEL. VIDEO”, “INPUT
SEL. SDI1”, “INPUT SEL. SDI2”, “INPUT SEL. YP
BPR/RGB” and “INPUT SEL. DVI-D”. 
 When “GAMMA SEL. FILM” and “GAMMA SEL. STDIO/PST” are activated at the same time, “GAMMA SEL. FILM” has priority.
The following diagram and the table on the lower right show RS-232C terminal pin arrangement and connections.
