Accell’s new interface hubs support DisplayPort’s multi-stream transport (MST) enabling independent monitor control and the support of high-resolution graphics. The UltraAV DisplayPort 1.2 to 2 DisplayPort Multi-Display MST Hub and Mini DisplayPort 1.2 Multi-Display MST Hub support resolutions up to UltraHD at 30Hz in MST mode. For a higher frame rate (60Hz), resolution is cut to 2560 x 1600.
The DisplayPort to 2 DisplayPort MST hub can extend a single DisplayPort output to two DisplayPort-enabled displays. The Mini DisplayPort 1.2 MST hub, meanwhile, is part of Microsoft’s Designed for Surface programme; it is offers Surface tablet owners a way to extend their desktop to external displays. Both hubs are compatible with non-DisplayPort outputs, such as HDMI, DVI and VGA. DisplayPort signals can be converted to other interface signals using active or passive adaptors.
Latency is said to be ‘near zero’. Power is supplied through a USB connection. The hubs are available through distributors worldwide now, for $80.
