The High-Speed HDMI cable also supports 3D and Deep Color technologies and is recommended for 4K capable video consoles and Blu-ray Disc players. It has a bandwidth of 10.2Gbps and is optimized for HDMI versions 1.3 to 1.4a. If you do, a different but not more expensive HDMI cable should work just fine. A High-Speed HDMI cable is designed to transmit 1080p, 4K at 30Hz, and 3D signals. In this case, you might get dropouts or sparkles (as discussed in this article). I hedge with "should" as if the cable isn't fully up to the High Speed spec, it might not work. Your current High Speed cables should work just fine. You can expect cable manufacturers to proclaim that you need expensive new "Version 2.0 cables" but this is untrue. Version 2.0 (like 1.4 before it) is entirely a hardware change. Here's another direct quote: "HDMI 2.0, which is backwards-compatible with earlier versions of the HDMI specifications." Current High Speed cables (category 2 cables) are capable of carrying the increased bandwidth." Emphasis mine. Here is the exact quote from : "Version 2.0 of the HDMI Specification does not define new cables or new connectors. The group is not saying it isn't possible, just deferring to the manufacturers.įor more info, check out HDMI 2.0 Upgrade Path: Where do the manufacturers stand? Since the specification and bandwidth are based on the HDMI hardware chips inside the products, getting these chips to do more than they were initially designed to seems a challenge, and that's likely why HDMI Licensing is hedging. The latest current version, HDMI 2.1, added support for both 4K and 8K video at 120Hz. Please check with them directly." Emphasis mine. Version 1.4 offered support for 4K displays, while 2.0 boosts 4K video capacity to 60Hz at 24-bit color depth. If there are such conversions, it would come from the manufacturer. Because of the new enhanced feature set, any such conversion would require hardware and/or firmware upgrades. From : "Currently, there are no provisions for doing upgrade. Sony is saying its products can do this, but says that's not universal. There's some confusion right now as to whether HDMI 1.4 products (like all current Ultra HD TVs) can be upgraded via a simple downloaded firmware update. 1080i and 1080p are the same resolution.TV tech explainer: Every HDTV technology decoded HDMI 2.0 (September 2013) upped bandwidth capacity to 18Gbps, allowing for delivery of 4K video at a full 50/60 frames per second that’s full support of the 4K video signals we expect today on new HDTVs as well as the 21:9 wide angle theatrical display format and better 3D video.Myths, Marketing, and Misdirection: HDTV edition.
