Putting HDMI in wall

[sjaisie]

I am looking for ideas of how to get HDMi cables up a wall about 1 meter to where the TV is going. Walls are plaster and brick, but will be getting skimmed again as I have a socket to put in that area too.

I’ve seen wall plates, nylon covers etc but what’s your opinion?

Thanks

Done this a few times using 25mm plastic conduit, you’ll need a 44mm metal back box at each end too and the cut into the wall will need to be about 30mm minimum

As Murdoch says you need quite a big channel in the wall as although the hdmi cable is usually quite thin the plugs on the end are not, and although you could just bury the cables in a shallow chase what happens if you want/need to swap them. Dont forget about a normal aerial cable and possibly a network cable as well. And secondly how does the power get to the tv.

Why do you need an hdmi lead in wall?

I am putting tv on the wall above a unit and don’t want any cables visible

I would chase out a large channel and then put in a much larger diameter conduit (or even 32mm waste fittings)

You're looking at HDMI but you don't know what you need in the future.

In my install I have a two low level power sockets plus a mid level double power socket.

I also have a low level "open" socket (with router connected Cat6) connected to a mid level open socket (with more Cat6) that then runs up to the window cill via a 30mm piece of flexible conduit. The aerial cable will run in via the window cill when I retro fit it (oversight - eejit)

This arrangement means that I can run low and mains voltage cables and any assorted cabling up and down to any present or future arrangement of required cabling for TV's soundbars and Freeview or Sky boxes etc

This preparedness is learned behaviour where I installed a massively expensive 3m SCART cable in 2006 without any ability to supercede it with any future technological developments

The attached pic show the arrangement with the green indicating the conduit. My TP Deco is hardwired and low-voltage hard-cabled for power. I haven't been brave enough to do the same for Alexa as yet

Actually the plumbing pipe idea would work great. I’m thinking a 90 degree fitting on each end of a short length of pipe buried in the wall with the fitting flush or even slightly proud of the finished wall.

Pulling any cable past just one 90 degree bend can be a headache.

This is our new TV position in the process of being installed over the fireplace. I know some of you frown on it, but we are going to replace the surround with a lower one.

The 2.5 was brought up in the RH corner and across behind the coving.

The Cat 6 and aerial cables were brought up in the LH corner and across behind the coving.

Mrs S wants the soundbar above the TV, so a short HDMI lead will link that to the TV.

I don't want to go near the flue with the drill, so will get a piece of 25mm ply that will easily bridge the flue and will attach recessed bolts from the reverse side to mount the TV bracket to it with. Into the 25mm ply, I will cut a single and double box cutout, so I don't have to chop out the chimney breast. The single box on the left is for a brush outlet for the co-ax and Cat 6, and the double box on the right is for an MK socket with USB outlets. One USB outlet will feed a Roku stick. I know the TV has USB outlets, but I don't trust their output to be good enough to feed the Roku.

There were previously two aerial cables terminating behind the old TV position (in from the aerial and out to another TV via an amp), so I re-sited these outside in a weatherproof box, with a third new cable running to the breast. Here you can see it is temporarily attached to a flylead running to the old TV position.

Ok I will use 135 degree bends then and trim flush with the wall, and perhaps cover with brush plates just for a neater finish.

What kind of device is sending the signal over hdmi? Is it small enough to mount on the back of the TV? (eg an Apple TV box)

It would be Sky Q box, Xbox etc, so not an option to mount behind

Do you still use the chimney?

No we don’t. The internal wall is flat so no chimney breast, it’s all outside.

I wonder if it's an option for running a cable in (drilling holes easier than chasing) or even stashing an Xbox/sky box etc in..
