Connecting Multiple Displays in a Daisy-chain
Configuration
You can interconnect multiple displays to create a daisy-chain configuration for
applications such as a video wall.
Things to know before connecting displays in a daisy-chain configuration:
1. If the signal is stable and there is no cable loss, in general, up to 25/12/9 monitors can
be connected via the DVI-I(Digital signal)/DP/DVI-I(Analog) Out port. To connect
more than these numbers of monitors, it is recommended to use a splitter.
2. If the signal cable between your computer and the product is too long, make certain to
use the booster or optical cable.
