As if it’s not bad enough with all this HDMI “stuff” that prospective purchasers also have to think about long IEC type 2 connector runs. In the days of analog video the dependability of signal transmission over long cable lengths was never a problem but in the early days of HDMI and DVI we heard rumors of consumers encountering difficulties over comparatively short jogs but things have improved over time but the actual length it is possible to run long IEC type 2 connectors over is still an industry hot potato.

Let’s look at the most recent HDMI specification for a reply to the inquiry. Every cable must be examined by the HDMI before they can gain conformity certification, authorized test centers. These certificates could be used as some kind of unofficial guide for cable lengths that were workable. A great piece of advice would be to buy certified cable using the latest specification, only at that time HDMI is at 1.3b, but 1.3 and 1.3a are also satisfactory, as the evaluation protocols these cables have to pass to receive the standard are more rigorous than for prior specification, say 1.1 or 1.2.

Nevertheless, there are available IEC type 2 connectors which are classed as productive which use powered amplifiers to increase the signal enabling longer runs of cable to be used. An EQ component is also used on these active cables which looks at lost high frequency data and after that compensates for this. These systems do work, but with no dependable information concerning real effective length, the added costs involved along with the additional possibility of signal delivery failure from the inclusion of extra components it could be a step to far for your own home entertainment system and best left to commercial uses.

But all isn’t lost should you have to run longer lengths of cables. As with all specification, in there will be built some leeway – over engineered – and therefore the source sign sent to the HD empowered equipment is not worse than is required for that gear to operate as said. This gives you several choices, alternatives that don’t fit to the specification alternatives that have been proven to work, although thus will not be promised to work as in the example above and do not possess the added costs of amplification.

There are connectors accessible which, although not compliant, will do a job not to mention there are the over length (for conformity) cables. It’s worth bearing in mind that the higher the bit rate your HD enabled gear is pulling the less likelihood of success you might have, should you be to go this way. In addition you need to understand this also applies to long chains, HDTV to Blu-ray or home theater connected to the internet streaming video on demand at 1080p will undoubtedly push cable lengths that are longer, those over a span that is compliant, to it’s limits. But for 720p 480p or 1080i they may work good. Does one see just this is often.

Now take into consideration future advances, which you should if you are placing these cables in walls etc., as though you’re running on the limits of the cables this could cease you updating. Take where we’re at present. 1080p is the newest resolution. Not that long ago 480p was the norm, afterward came 720p and 1080i which runs on the bit rate almost three times that of standard 480p. Then along came 1080p that doubles the bit rate consumption of 1080i and 720p. Now we stand on the edge of 3D TV, 16 bit color and 1460p (and above), 16 bit colour alone will double the required bit rate for current standard resolutions, so you see where this could go. One more significant point to think about when deciding whether to go or not. It is true that on short cables, those of 2 -3 meter (6-10-foot) length, the quality matters less. A cable costing several dollars will perform equally as good as one costing tens of dollars, but when entering the worlds of none conformity quality matters much more. Generally speaking, the lesser quality the cable is then the lower the effective working distance will be when depth of image or color resolution increases.

Lets unravel what is been said seeing their reliability as well as long IEC type 2 connectors. For the spans that are HDMI compliant, those spans up to about 13 meters (45-foot), their use is pretty much ensured, even if you’re using the more affordable alternatives, for 480p, 720p, 1080i and – even if much less consistently trustworthy – 1080p thus just do it and use them with confidence. Precisely the same is true for those shorter cables of 1-3 meters (3-10-foot) lengths, though care should taken when using them as they may become unreliable. More low-cost alternatives of the longest HDMI compliant cables working on the limits of it is performance capabilities may fight in the 1460p, 16 bit colour future and their use has to be challenged if their installation is behind ceilings or walls as the additional expense of a more costly cable may be less than a whole re install in the (not to distant) future. The use of over compliant span IEC type 2 connectors needs to be linked to each of the factors mentioned above but with all the rider the best approach to testing if it will not be unsuccessful lies with plugging it in. At these lengths, the alternatives that are more affordable continue to be worth considering if the installment of long IEC type 2 connectors those bought from┬áis easily reached plus they work OK together with your current gear.
