I just want to know what the difference is with a 2.0 cable and a standard hdmi cable
Thank you very much for contacting 123inkcartridges.ca.
HDMI 2.0 was announced as a standard in late 2013. It got a lot of people confused, wondering if they suddenly needed to throw away their TVs in order to get on this latest tech trend.
As far as tech advancements go, HDMI 2.0 is a pretty friendly one. It’s as much a standard of software as hardware, and cables designed for HDMI 1.4 systems will work just fine with new HDMI 2.0 devices.
What you need to make sure is that both ends of your entertainment chain – your TV and blu-ray player, for example – support the standard. It’ll mean they’re geared up for the new standards we’ll dig into shortly. Some previously HDMI 1.4 hardware needs nothing more than a firmware update.
HDMI 2.0 is a reimagining of the interchange between your bits of home entertainment gear, one that factors in the immense amount of data required to get high-quality audio and video to something like a 4K 3D-capable TV.
Give it a year or so and 1080p TVs won’t even feel current anymore. We’re already starting to see 4K sets fall under the £650. It won’t be long before the rubbish 1080p LCD TVs at Tesco are replaced by rubbish 4K ones. Exciting times ahead.
HDMI 2.0 itself isn’t really about resolution, though, but bandwidth. More bandwidth is what makes all of its new standards possible. HDMI 2.0 systems can transfer data at up to 18Gbps, up from 10.2Gbps in HDMI 1.4.
In terms we’re all more likely to get on with, 18Gbps is 2,250MB a second. For a little more context, normal Blu-rays max out at 54Mbps, or 6.75MB per second. The HDMI pipe is wider than a dual carriageway.
HDMI 1.4 introduced the kind of bandwidth required to deliver 4K video, but HDMI 2.0 can dole out 4K video without compromise, at 50 and 60 frames per second. In HDMI 1.4, the rate of 4K was limited to 24 frames per second.
24p and 30p are perfect for watching films, but there are times when the extra speed of 50p and 60p come in handy. Gaming could make great use of 60p content, while more films are being shot at higher frame rates, giving quite a different look from that of slow old traditional cinema.
● HDMI cables (which stands for High-Definition Multimedia Interface) comes with 3 different sized connections; standard – mini & micro. MINI HDMI is used on many new high definition camcorders and high resolution DSLR cameras (like Sony or Canon for example). MICRO HDMI is the smallest current HDMI connector. It is used on mobile devices like HTC, Samsung or Motorola. The standard version of HDMI is the first choice when connecting any HDMI ready devices.
● Used to carry high definition digital video signals avoiding most picture degradation that can come with analog signals. These cables can be used with a wide variety of devices like HD satellite or cable boxes, laptops, media or home theatre receivers to HD monitors.
