consult professional and technical personnel if you want changing.
Adjust Brightness Based on Multi-function: Check it if you need
multifunction’s light sensor automatically adjusts the LED screen’s
brightness.
DVI Information: The parameters automatically collect by the software from
the sender card.
Could By Pass Switch: When the gigabit switches as transfer equipment,
then required checking this
Output Frame Rate: the software default is “Every Frame”, please consult
professional and technical personnel if you want change to “Every Other
Frame”
