We’ve received some customers who are looking for the HDMI cable over 50Ft, and wandering about their quality of these over distance cables .
Cable HDMI -123inkcartridges
HDMI Cable has improved a lot recently, but it will never rival analog video for reliability over distance. The rumor said the most effective HDMI length would be 15Ft, actually, the HDMI doesn’t tell the effective length limit. What this useful spec of HDMI is called compliant. A compliant cable should meet either an eye pattern test or a set of parametric test. Those two tests are measure the HDMI cable from overall shape to losses in the signal.
Most of users would chose use a powered amplifier to compensate for the loss of high-frequency information. These amplifiers and EQs provide new potential points for failure in signal delivery, and make diagnosis of problems more complex; still, if you need to run extreme distances, check the reasons below to have better choices.
① Usually, the spec of HDMI is written with the intent of ensuring of any compliant source, will work. And the signal coming out of the source is probably better than the minimum signal required by the spec. And the bitrate running in the cable corresponds directly to the amount of information in the picture. Normally, standard HD resolutions 720px 1080i use nearly three times the bitrate of standard- definition 480px 1080p.
② For having perfect HD solution, it is said that shorten the standard cable up considerably does workable. Such as , 480p works good at 180 feet, 1080p performs great at 125Ft, 720p runs well at 150 Ft. The hardest thing to get right in HDMI cable is high-frequency performance, and so generally speaking, the lower the cable quality, the more the working distance will fall as resolution or color depth rises.
③ Another factor in these distance are the headroom provided by the source and the display. The HDMI running distances will be limited by the display’s data recovery characteristics and source signal.
In short, if you are going to enjoy HD resolution at home, better go with the HDMI cable distances 50 Ft and shorter, For those extreme long runs, low-cost 50 Ft cables which are near their performance limit at 1080p today may not work with color 1080p tomorrow. Whatever, HDMI cable performance is hard to predict without plugging it in.
