OWC has announced a new kind of USB dock, rated to split 1 Thunderbolt feed between 2 monitors of (technically) up to 8K in resolution. It does so via the newer DisplayPort 1.4 standard, and is also rated to support HDR with compatible displays. OWC asserts that this new accessory can thus boost productivity, gaming or learning for a variety of users.

OWC is known for its USB type-C, often Thunderbolt, docks as well as its memory upgrade and storage kits. Many of the former connect a PC to a box containing a wide variety of ports and inputs via a single cable. However, the latest offering from this OEM is more focused, as it has just 2 of the same kind at one end, with the requisite type-C port at the other.

Both are DisplayPort rated for the latest 1.4 version of this standard, which can support resolutions of up to 4 times higher than its 1.2 predecessor. OWC claims that both ports can drive an 8K monitor - however, this is in Display Stream Compression (DSC) mode only; should the user want this top-end resolution at 30 hertz (Hz) or higher, only 1 monitor can be supported.

Otherwise, this new OWC Thunderbolt Dual DisplayPort Adapter can handle dual 4K monitors at 60Hz or at 144Hz with DSC. The OEM also asserts that the new accessory can support "multichannel, high-definition digital audio formats". The adapter is available from now for US$78 on
