This article has to do specifically with the Ultimate 11-in-1. Please use the main page to look up your HyperDrive if this is not it.
- Please note, if your device does support more than one monitor, you must use Mini DisplayPort as one of the monitors, and HDMI OR VGA (they do not work together) can be used as the second.
- On Windows devices that support USB-C for video, you can use up to two additional video outputs through extended mode with this Hub.
- An important note: Due to a large variety of Windows computer models and specifications, you need to make sure that USB-C port/ports on the computer support Display Alternate mode with MST. Please contact the manufacturer of your computer to make sure this is supported.
- macOS devices can only connect to one extended video display, or two mirrored displays, through this Hub. This is a macOS limitation.
Why can't I use two displays on a Mac computer?
The reason has to do with the technologies for display used in macOS computers vs Windows computers. Mac utilizes Single Stream Transport (SST), while Windows allows for Multi-Stream Transport (MST) on most devices:
- What are SST and MST? In order to achieve 4K resolution at 60Hz, most early 4K displays on the market used Multi-Stream Transport (MST), a technology that stitches two halves of a display together into one large surface -- also called a "tile" -- in software. MST, supported on Thunderbolt 2 Macs, can carry a signal for two or more monitors on a single cable, allowing for daisy-chaining or hub configurations of multiple 4K monitors.
More recent 4K displays have started using Single-Stream Transport (SST), eliminating the need for stitching two halves of a display together in software. Instead, SST monitors feature scalers that support 4K resolution at 60 Hz over a single tile. Ideally, if you are purchasing a 4K display, you should look for one that supports SST, since MST can cause issues with in-game menus, BIOS screens, and scaling.
On Mac OS with Intel's processor lineup, it supports DisplayPort 1.3. Macs with DisplayPort 1.3, will be able to drive a 5K display over SST, eliminating the need for Apple to worry about syncing two channels over MST.
