DisplayPort Alt Mode 2.0 will allow 16K video output over USB 4 Type-C ports – TechWeu
The Video clip Electronics Standards Affiliation (VESA) just lately launched variation 2. of the DisplayPort Alternate Mode (Alt Method) standard which enables up to 16K video clip output in excess of USB 4 Type-C ports.
As a report from AnandTech points out, the new normal remaps USB Type-C‘s superior-velocity details pins to unlock far more bandwidth for video clips, ensuing in a utmost raw bandwidth of up to 80Gbps.
This is completed by reconfiguring a 4 lane USB 4 connection into a 2 or 4 lane DisplayPort relationship and driving DisplayPort alerts over significant-speed lanes which would otherwise be carrying USB 4 signals.
In a statement pertaining to the new conventional, Craig Wiley, senior director of marketing and advertising at Parade Technologies, VESA board member, and DisplayPort Alt Mode sub-group chief, was quoted saying,
“VESA’s up to date DisplayPort Alt Mode spec incorporates a variety of beneath-the-hood developments — together with updates to interface discovery and configuration as properly as energy administration — to be certain seamless integration with the USB 4 specification…This big undertaking, which was several a long time in the building, could only be created attainable via the merged endeavours of VESA and the USB-IF.
As a result of our most current collaboration with the USB-IF, VESA is now taking care of almost everything relevant to superior-performance displays over USB-C, no matter if by means of a native DisplayPort or USB-C connector, or as a result of tunneling of DisplayPort over the native USB 4 interface.”
For the unaware, USB 4 relies on a 2-up/2-down configuration to type a bidirectional relationship. Considering that video alerts don’t need to have to go equally strategies, DisplayPort Alt Mode 2. can acquire around all four lanes. In essence, this indicates that a DisplayPort Alt Mode 2. connection will be as able as a standard DisplayPort 2. link as much as connectivity and bandwidth are anxious.
On top of that, the new typical does not demand users to have a USB 4 controller on either stop of the cable, which signifies that you will be equipped to use your current displays with DisplayPort hardware without upgrading to a USB 4 supported observe.
