Although not explicitly stated in the press release, 25.92 Gbit/s of bandwidth does allow 4K (3840x2160 px) x 24 bit RGB @ 120 Hz (or dual 60 Hz) for computer monitor displays, using CVT Reduced Blanking 2 timings defined in CVT r1.2 -2003, which can be used for stereoscopic 3D displays.An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane—a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort’s 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable, without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort’s Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
