10.4. EDID Management
The Extended Display Identification Data (EDID) is used by the source device to match its
video resolution with the connected display. By default, the source device obtains its EDID
from the connected display, but when the video resolution of display is higher than
4K@30Hz, the video resolution of source device will be 4K@30Hz.
Meanwhile, since the display with different capabilities is connected to the switcher, the
below RS-232 commands can be used to set the EDID to a fixed value to ensure the
compatibility in video resolution.
