What is Energy Saving LED Display
Is there any priority of the 2pcs RJ45 ports of the sending card for LED Displays?
Yes it is.
Take NOVA MSD300 sending card as an example, see below picture, port 1 is the priority port.
So if your screen is less than 650000pixel, use port 1 only to connect receiving card and loop all of receiving cards.
If your screen is more than 650000pixel, connect port 1 with receiving cards group1 by CAT5 cables, then connect port 2 with receiving cards group 2 by CAT5 cables.
