Check if EXTERNAL DEVICE is set in OPTION -
SERVICE - HDMI OUT RESOLUTION.
Set PROJECTOR in the menu above.
Disconnect the LAN cable and check that the
projector is working properly.
If this issue occurs after connecting to the network, there
may be a loop between two Ethernet switching hubs
within the network.
- Two or more Ethernet switching hubs are in a network.
- Two of the hubs are doubly connected by LAN cables.
- This double connection forms a loop between the two
hubs.
Such a loop may have an adverse effect on the projector
as well as the other network devices.
Check the network connection and remove the loop by
disconnecting the LAN cables such that there is only one
connecting cable between two hubs.
