A pretty base problem that comes with the coming of Hdmi (High Definition Multimedia Interface) becoming the new commerce accepted for transmitting Tv signals is how to make your mind up the precise length Hdmi lead. In the old days when all things was carried by Rg6 Coaxial cable, it was inherent to run the signal over pretty long runs and then naturally cut the cable to length and fit a coax connector and naturally associate it to the Tv. Although Rg6 cable is still used to associate the satellite dish to say for example a Freesat+ receiver, the output from the box to the Tv will now invariably be a Hdmi cable.
Another complicating factor is the popularity of hanging Flat screen Tvs on a bare walls or over a fireplace. Obviously nobody wants Hdmi cables tacked along the wall, so invariably the cables are being buried in the wall and commonly run from the Tv to a around built in unit which will house the satellite receiver. What makes selecting the precise length of lead is that it is not inherent to naturally expand or shorten the lead. In normal there is a good option of Hdmi cables fluctuating from 1m all the way up to 20m, with the upper limit being due to the level of signal loss that occurs in cables that are no longer than 20m.

No matter how well you plan it there is always a possibility the the cable will too short. For example the Hdmi input on your new Hd Tv is in a distinct location than you expected, or you resolve to mount the Tv in a slightly distinct location. There are 2 options when it comes to extending a Hdmi cable.
The first and simplest option is to naturally use a Hdmi coupler which comes with sockets on both ends into which to insert Hdmi cables. This option is both inexpensive, ageement and does not need a power supply. It is however only favorable to use when the combined length of the 2 cables is less than 20m.
The other option is to use a Hdmi repeater, which is a powered unit that both joins 2 Hdmi cables together and also boosts the signal. commonly this unit is used when combining Hdmi leads where the combined length is over 20m. The need to have the unit plugged in and its cost are for real issues, but this is an considerable unit on very long runs.
A final note on Hdmi cables is that in normal over short runs, the discrepancy in the signal loss in the middle of a low cost and an costly Hdmi is pretty minimal. Where spending the extra money is worth while is on long runs of cable. Most of the cost lost Hdmi victualer don't do funds level cables that are longer than 5 or 10m.

ReplyDeleteFirst of all, HDMI version numbers have no relationship to the cables. An HDMI cables will not alter the features that are available from a TV or any other piece of equipment.
