Are HDMI Wall Sockets inferior?

Looking for some guidance on this.

My mum is renovating her unit and we are getting her 42" 1080p tv mounted on the wall. We wanted it to be a clean install so requested a wall plate behind the tv and one below to pass the HDMI cable. Then all the cabling can be dug into a channel inside the wall.

The builder/electrician have gone ahead and installed the wall plate, but instead of terminating the HDMI behind a socket, they are running a single HDMI through the wall plates. Initially they said there was no room behind the plate as it was a single brick wall, however they've created a bigger void for the CAT6 plugs. They're now saying its not industry standard, the resolution will be degraded and that it will be an inferior job.

I get the idea that running a single cable is better, but I dont imagine the loss would be that significant in this instance.

Does anyone have any experience with this?

    The HDMI connectors will look much better, but you'll have to use more cables (5 in total). It may affect 4k or 8K, but for 1080P, it's not going to make any difference.

    If it was me, I'd probably run it the same way as the builders as you'll never see once the TV and entertainment unit is in place. But since you paid for it, yeah just push it.

    I'd be more concerned with the paint job.

    Thanks for the reply. I was thinking 3 cables, but didnt consider the leads off the back of the socket.

    One other thing is that TV wall mount is going to allow the TV to be perpendicular to the wall, so it will face the couch. (small living room) So when pulled out like this, you will be able to see the space around the cable as it goes through the wall plate. I forgot about this, but this confirms it needs to be redone.

    But I'd also be interested to see if anyone has experience with this HDMI socket type on 1080 or 4K TVs.

      The other option is to get a bull nose plate installed.
      Neater look without all the HDMI joins

        Perhaps or a brush plate. Thanks

    Not sure about the hdmi, but it's lazy if they plan to leave the coax aerial fitting like that.

      Yes, already raised it :-)

    Playing off an older xbox, I was getting green pixels at various locations across the screen (1080p). Each individual cable would work perfectly fine in a single direct connection to the TV, but using the various wall joints adds a lot of potential points of signal degradation.

    No harm in testing them out before fitting everything into the wall.

      Helpful. Thanks

    Why a 1080p TV? Spending all that money on cabling and then putting in a shitty old tv seems weird.

  • antojamo on 16/06/2022 - 11:19

    She doesnt care about resolution. Will upgrade when this one fails.

    you wont have much degradation issue with those joints, it only become issue if cable run is very long (>3m) and you go to 4k territory. I ran about 10m hdmi with 2 extra short cables behind the plates on both ends and got away with 1080, but as soon as I switched to 4k the screen went blank.
