Special Notes / 
Requirements
Note
DisplayPort 1.2 with MST+HBR2 support from the GPU is required for 
independent display output
When using a DisplayPort 1.1 video card the MSTMDP123DP will act 
as splitter, automatically mirroring your video source across all 
displays. Resolution limitations apply
Certain graphics adapters have limited MST support and will only 
output to three displays in total. If more than three monitors are 
attached the fourth will be disabled.
