When "Compute EDID" mode is selected, the system dynamically generates the

4.2 Compute EDID

EDID for each input according to the "highest common denominator" of the TVs
that are routed to that input. To select this mode:
Press MENU and navigate to "COMPUTE-EDID" and press SET.
Press SET again to confirm.

When the "Compute-EDID" mode is enabled, routing an input to multiple TVs

with different capabilities will force the system to "compute" a new EDID for
that input based on the TV with minimum resolution capability. Therefore, in
this mode if the EDID changes a short interruption may result in the video signal
from the source as it changes its resolution.
Example: say you have two monitors, one that supports 1080p and one that
supports 4K. When a particular input is routed to both of these outputs, the system
will compute an EDID with 1080p for the input because a 4K signal would not be
displayable on the 1080p monitor. Now let's assume the user disconnects or
switches the 1080p monitor to a different input. Then, the only monitor routed to
our source is the 4K one. The system will notice this and re-compute a 4K EDID for
our input causing the source to output 4K video (if it can). Switching takes a
couple of seconds. If the 1080p monitor is turned back on or routed to the same
input, the system will downgrade the EDID for the source to 1080p.
