In this case there are four groups LED display screens, each group need a
LED-540. The four machines unequal splicing parameters must be set as the

After finished the system constructing, need to test the splicing effect, if
"synchronous follow-up" function cannot be successfully launched (namely
synchronous follow-up icon are not displayed for a long time), then need to
add a LED-540 to do signal shaping, and the above four sets LED can share the
plastic signal by itself DVI loop out port.
Following is the system diagram

The diagram above, No. 1 and No. 4 the four sets of input signal LED-540
completely consistent. To reduce DVI signal ring after series, will signal plastic
LED-540 two losing exports are still used, so can reduce half of the ring after
series.
The above Mosaic example, used the two outlet of the LED-540 for signal
plastic, and this is to avoid the unstable phenomenon caused by the more DVI
signal loop series.
