DP OUT (MST/SST) Function Implementation

Connecting a PC via DisplayPort

――If the MST mode is selected for DP OUT, FreeSync is not supported for all connected monitors.

――Before selecting the MST mode for DP OUT, make sure that the device supports DisplayPort:MST (Daisy Chain)/HBR2 (High Bit Rate). Incorrect settings may lead to black screen or inconsistency between the actual output mode and the selected output mode. If a black screen occurs, change the DP OUT output mode.

•• MST/SST: A technology used for connection and driving of multi-stream display signals.

‒‒ MST: Stands for Multi-Stream Transport. Can transport multiple video and audio streams, but needs the support of both the drive capacity of the graphics card and the resolution of the monitor.

OSD → DisplayPort:MST

‒‒ SST: Stands for Single Stream Transport. Can transport only a combination of a single video stream and a single audio stream.

•• Make sure that the graphics card supports the MST (Daisy Chain) function. To check this, visit the website of the graphics card manufacturer.

•• The output mode of DP OUT varies with the settings of DisplayPort Ver. When DisplayPort Ver. is set to 1.1, DP OUT only supports SST.

•• When connecting a PC using DP cable, you must set DP OUT mode to "DisplayPort: MST (SST)" on the OSD menu. (OSD – System – DP OUT - DisplayPort:MST/DisplayPort:SST)

•Because of the bandwidth limit of DisplayPort Ver. 1.2, up to two 2560 x 1440 @ 60 Hz monitors can be connected and used. But this specification may vary depending on the cable used and the performance of the graphics card.
