Special Notes
  • A 4K-capable display is required for obtaining the 3840 x 2160 resolution
  • When connected to a DisplayPort™ 1.1 or older video card, the adapter will function as a splitter, automatically mirroring your video source across all displays. Resolution limitations apply.
  • macOS® does not support MST and will only support mirror mode, but not extended mode, regardless of whether or not the video card does. This is an operating system restriction.
