DisplayPort Alt Mode 2.0 is the new Association for Electronic Video Standards (VESA) standard that enables the USB 4 capabilities of the DisplayPort 2.0 standard, as well as the transmission of information via USB, according to The Verge.
This means that USB Type-C will be able to transfer 8K to 60Hz signals with HDR, 4K to 144Hz signals with HDR, or even 16K to 60Hz signals, with compression. Getting around is an important step in turning a USB Type-C into a good connector.
Why good at all?
USB 4 can now transfer information from DisplayPort, but AnandTech explains that the new standard remaps USB-C high-speed data pins to allow for more video wavelength. USB 4 is bi-directional, which means it can transfer up to 40 Gbps of data in both directions.
However, video information does not have to flow in both directions, it only needs to be transmitted from the source to the screen, for example. The new mode means that all the bandwidth can be used to transmit video signal in one direction, that is, it reaches transfers of up to 80 Gbps in one direction.
The explanations are very simplified and are taken from the VESA announcement about Alt Mode 2.0. The company announces that devices with DisplayPort Alt Mode 2.0 will launch starting next year.
