November 29, 2017 |Industry Notes

The HDMI Forum announced release of the HDMI Version 2.1 specification, nearly 11 months after it used a January CES news conference to say it expected the spec’s “upcoming” release would take place in Q2 (see 1701040065). HDMI 2.1 supports doubling the frame rates of 4K video to 120 Hz and 8K to 60 Hz, and supports high-dynamic-range platforms that use dynamic metadata, such as Dolby Vision and HDR10+, said Tuesday's announcement.
