EXCESSIVE HDMI CABLE LENGTH ....

Post by eliwhitney »

Good Morning Richard -

This all began sounding all-too-familiar .

After "searching" , it has all been explained very extensively, including your Blue Jeans reference, {to this very poster!} with no success at all --- apparently, none of the previous data amounted to "beans?"

Cable length.

Post by blazzer_19 »

Hello Eli,

I appreciate everyone's help. I did look at the bluejeans link and it was helpful. However ... when it refered to cable trouble it refered to an unclear or distorted image. It never mentioned not receiving a picture at all. It never indicated if an HDMI repeater would assist this. I am also trying to get as much info from multiple sources prior to spending any more money. Blujeans refered to using HDMI lengths of longer than 75' with little or no loss. Now I am trying to figure out if I need something else like a booster or if it is a faulty cable? I realize I can go to component cables that is not the issue. I know that component will do 1080 I and the HDMI cord will do that at least and I am probably not going to acheive 1080p at a length like that. So if it is going to cast much more money I may switch to component. See I bought this 75' HDMI cable on ebay a while ago because it was a "best offer" and I got a good price. I didn't do much reasearch before buying. Anyway I am very greatful for everone's help here and if anyone has more to add please do. However Eli...I don't appreciate the tone in your post about me. I am new to this and am learning. Your info was good and did mean more than an amount of beans. Thank you all.

Darryl

Hello blazzer_19 -

I offer you apologies if you took offense - but - from the vantage point of us, you did simply ignore every single bit of all of it --- and, did it anyway. And, even at Ebay prices, those were monies that could have been not spent.

No one should ever buy electronic gear from Ebay & expect outstanding quality! The technical attributes & criteria are never assured or guaranteed.

Bluejeans also mentioned the engineering facts about a much heavier gauge of conductor having been absolutely needed.... Ebay materials seldom have any such criteria available.

By offering suggestions, it is hoped that others might avoid the "school-of-hard-knocks" learning experiences that some of us have gone through already.

HDMI/DVI either works or it does not work. When the limitations of cable performance are on the edge it creates artifacts unrelated to image quality (it is digital - not analog) such as colored noise, discoloration, half screens, pixel blocking.

They were referring to THEIR cable.

BJC Series-1 Belden Bonded-Pair HDMI Cables: Our best cable for distance runs.
http://www.bluejeanscable.com/store/hdm ... /index.htm

It is certified under HDMI 1.3a (CTS 1.3b and b1) at the longest distances of any cable we know of--45 feet for Category 1, 25 feet for Category 2. In actual usage, it ordinarily will work at distances exceeding these--we have run 1080p video through a 125 foot cable without any information loss, but results will vary depending on the capabilities of the sending and receiving circuits of the devices in use.

Go to Google, input: HDMI repeater

I think Richards on the correct track. The da/repeater could certainly be the entire cause of the problem. A lot of early da's only supported HDCP on one port. In any case I don't remember mention of the HDMI distribution amp model or brand. Some brands have trade in programs or at least support for problems. Of course they will complain about a 75 foot length cable, unless it's "their" cable.
What is your distribution amp?
