The DisplayPort Alt Mode was announced back in 2014 with a new standard it calls DisplayPort Alt Mode 2.0 has been refreshed by the Video Electronics Standards Association (VESA). The DisplayPort Alt Mode 2.0 carries the features of DisplayPort 2.0 to USB 4Â devices.
In simpler words, users can enjoy the perks of DisplayPort 2.0 such as support for 8K 60Hz monitors with HDR, 4K 144Hz monitors with HDR, or even 16K (15360Ã—8460) 60 Hz monitors.
From our write up on “Everything You Need To Know About The USB 4″, youâ€™re probably see that USB 4 offers a maximum speed of 40 Gbps and DisplayPort 2.0 goes up to 80 Gbps. However, since USB 4 follows a bidirectional connection and the video doesnâ€™t have to be sent in both ways for a monitor, DisplayPort Alt Mode 2.0 makes use of this nature to offer the same speeds.
VESA in a press release said that;
â€œWith DisplayPort Alt Mode, the USB-C connector can transmit up to 80 Gigabits per second (Gbps) of DisplayPort video data utilizing all four high-speed lanes in the cable, or up to 40 Gbps with simultaneous SuperSpeed USB data delivery.â€
And according to AnandTech, DisplayPort Alt Mode 2.0 doesnâ€™t really demand USB 4 controllers on both ends of the connection like DisplayPort 2.0, which brings in better compatibility and some cost-cutting measures.
â€œWith the new DisplayPort Alt Mode 2.0 specification, USB Type-C now delivers compelling single-connector solutions for docking, gaming, AR/VR HMDs, and professional HDR displays that combine 80 Gbps of video bandwidth and other important features of DisplayPort 2.0 with the transport of USB data and power delivery,â€Â says VESA board vice chairman Syed Athar Hussain.
VESA says the first products supporting DisplayPort Alt Mode 2.0 are expected to be available in the markets as from 2021.
