Sony HDMI 2.0 Upgrade

Sony has just posted a firmware update for it’s Bravia X9 4K Ultra HD TV line. The update enables HDMI 2.0 functionality, which was announced at IFA 2013 back in September.

Sony detailed the firmware update earlier this week, stating that once the update is installed on their X8 and X9 line of 55- and 65-inch 4K Ultra HD TV’s, the set will be able to receive 2160p/60 signals through the fourth HDMI port. This HDMI 2.0 update will allow playback from a variety of sources, including future 4K physical media (4K discs), 4K game consoles, 4K satellite receivers, and 4K upscalers — to name a few.

HDMI 2.0 improves a number of features for 4K Ultra HD TV owners, the most important being the refresh rate, which will deliver 4K video at both 50 and 60 frames per second for both 4,096 × 2,160 and 3,840 × 2,160 resolutions — compared to 24fps/ 30fps offered by HDMI 1.4. Specifically, the update will be HDMI version 2.0b, which allows for 4:2:0 color sampling, 8-bit depth, and 50/60 frames per second, with a max data bandwidth of 10.2 Gbps.

The HDMI 2.0b update can be downloaded from Sony’s website, placed on a memory stick, and loaded into the 4K TV for installation. Over-the-air updates are planned for the future.

Sony’s 84-inch KD-84X9005 cannot be updated using firmware or software, instead it requires a hardware upgrade. Information for an HDMI 2.0 hardware upgrade will be released next month.
