Exploring the differences between standard and high-speed HDMI cables
1 Dec 2011 20:40:30
Contrary to what some people believe, there is not just one type of HDMI cable. You can find different versions and lengths of HDMI cable, as well as those which offer different functions, speeds and capabilities.
One of the most common confusions when shopping for HDMI cables is the difference between standard cables and those that are billed as ‘high speed’ HDMI cables. The question most people want answered is whether it is worth shelling out a little more money for the latter variety, or whether standard HDMI cables will suffice.
Let’s look at standard HDMI cables first. These have been tested to perform at a certain speed, which is 2.25Gbps or the equivalent of a 720p/1080i signal.
However, high speed HDMI cables have been tested to ensure they perform at much greater speeds. They have a bandwidth of 10.2Gbps, which means they can handle 1080p signals, as well as increased colour depths and higher resolution displays.
High speed HDMI cables generally cost a little more than standard varieties, but they can perform so many more tasks and at greater speeds. This is why it may be worth spending a bit more money on high speed cables to benefit from the superior performance they offer.
