Use of HDMI wall plate

[ecologydoc]

I have two Monoprice 60-foot HDMI Redmere cables and I tried them and they work fine. I'm going to run them under the floor and my question is, if I use an HDMI wall plate and connect the long cables to it behind the wall, will there be any issue having an additional 2- or 4- foot HDMI cable from the wall plate to the components? The alternative is just bring the 60-footers up through a hole in the floor all the way to the components; not as tidy.

I think there wont be any issues doing that as long as your connections will hold on. Tho I myself prefer as few connections as possible.

I've done it exactly like that and it works just fine.

Would the short cables also need to be one-way cables or does it matter?

An installer I used for my patio speakers just wrote that he would be leery of long HDMI cables (guess I neglected to mention to him that I had already tried them out and they worked fine, heh heh), and recommended cat5 cables with a powered converter, says it would cost more but be more reliable and better performer.

Ultimately, HDMI is a digital signal and the beauty of digital signals is they are digital, as in on or off. Thus, interference that might introduce noise has to be strong enough to switch an "on" to an "off" or vice verse. Within practical applications, such interference does not exist.
So, as far as data transmission goes, as long as the wires and connections are intact, you are good!

That's not true at 50-60 foot lengths with HDMI, because now you're dealing with the wire's ability to correctly transmit that signal level over that distance.

Many thanks for the correction BSA!
I have a friend who has had a 50 ft. run for a couple of years with no problems, but it seems the source comes into play.

Here is a post from Tom's Hardware Guide:

For me when I send 1080p over 50ft it is not working well. There is flicker from apple TV, another media player intermittently goes blank and back again. Lowering to 1080i works. I did buy cheap cable from ebay. Now I have to do some research to see what is the max distance I can go. Somebody should do the bandwidth analysis and the ack analysis to see what is a good distance after which it degrades.

You have to consider the weakness of comparing an appletv device to a full system gaming rig. This may be more the signal source vs the cable's ability to transmit at that length with your given signal source if that makes sense. A gaming rig with a discreet graphics card powered by a 1200W PSU is a huge difference. Others may want to think about that when going for longer cables like I did. So you could get the same cable and maybe your device isn't pushing a signal strong enough through that distance so results will then vary.
Not to say you didn't actually get a lesser cable but I just thought of all of this after reading your post.

This would explain why it would not be recommended as a rule, despite many being able to do it without incident.
Since it is comparatively easy and inexpensive to test, probably the best answer is to try it and if it works in your setup, you just saved some money!

Monoprice tech wrote me back, can someone please translate? Thanks.

"ideally for the redmere cables it's best to have them as direct connections between the Source and the TV. Using them with an HDMI wallplate, coupled to shorter cables can introduce issues as the cables would not be able to draw power from the display and the source."

Then Monoprice suggests using a pass through wall plate.

You have to use the Redmere cable first, plugged into the source. This allows the Redmere cable to do what it does. If you plug the normal cable in first the Redmere cable cannot 'boost' the signal.

FYI; if you want to, you can use a small Redmere cable and then a standard long cable and get the same effect as a long Redmere cable.
