DisplayPort multistreaming over USB Type-C or DisplayPort
If you are using USB Type-C or DisplayPort as the primary video input source, you can multistream to other
DisplayPort monitors connected in a daisy-chain configuration. If you are using the 68.6 cm (27 in) model, you
can connect up to three monitors in this configuration if the graphics card in your computer supports this
configuration. If you are using the 63.5 cm (25-in) model, you can connect two monitors in this configuration
if the graphics card in your computer supports this configuration.
The number of monitors you can connect through DisplayPort multistreaming depends on a number of
factors, including the resolutions and scan rates used for each monitor and the capabilities of your GPU or
embedded graphics system. If you have purchased a new graphics card for your computer, check the manual
that came with your graphics card for further information about its capabilities.
To multistream:
1. Be sure that USB Type-C or DisplayPort is your primary video input.
