My garden office is currently in the process of being built so I need to start planning cable runs for all the computer and AV equipment that will be going in their.

My current setup is a Sony 1080p projector and a Yamaha sound bar. The projector will be mounted in the ceiling on one side of the office and the soundbar and screen will be mounted on the other.

Currently the equipment is in a room in the house and I run a long HDMI cable from my computer desk chased through the wall to the soundbar, then another cable through the ceiling from the sound bar to the projector. This lets me plug in any HDMI source from my computer desk and play it through the projector\soundbar.

This works but it was a bit of a dirty install so when I transfer all this stuff over to the office I want to find out of there is a way of doing a better job and future proofing this. I could just put conduit in and still run HDMI cables through the walls\ceiling. This is a relatively cheap option and still means I can replace the HDMI cables relatively easily if they break or I need to upgrade them. The little HDMI switch box I'm using seems to be a bit temperamental though.

The other option is to put in Cat 6 and run HDMI over Ethernet but I'm not exactly sure what's involved in that. I assume I am going to need HDMI to Ethernet converters at either end and possibly some sort of receiver box. The cable runs won't be very long, less than 10m at a guess so is the expense of going cat 6 worth it?

Any advice appreciated.

At those sort of distances, I would stick with HDMI, 10m meters of good quality should be fine, I am running a 15m at 4K 8Bit with no problem.

Have a look at ACA-Apex's web site as they have a really good conduit kit you could use.

Excellent thanks! thumbup

Any recommendations on a decent 4k compliant HDMI switch box? I'm currently using a little mini hdmi hub but I don't think it's up to the job as it often doesn't switch over or recognise sources properly.

Why not run both? CAT 6 is not very expensive any you will future proof yourself.

10m HDMI is fine for 1080p, anything more you might struggle.

2160p 8 bit is achievable, but forget about 2160p 10bit which is needed for HDR.

Yes this is what I was thinking, 1080p is fine for now as that's what my projector is as well as most of my sources but if if\when I upgrade to a 4K projector and ultra HD sources in future, I wasn't sure if a long HDMI cable would cut it. You can apparently get 10m HDMI cables which seem to be rated for 4k but I'm not sure how much of the that is sales hokum?

I'll run the conduit and put both HDMI and CAT 6 in so won't have to faff around in future. I can just leave the cat 6 terminations coiled up in the wall plate boxes for now.

I've got a temporary set up at the moment before I move home. Run a 10m hdmi to a 4k projector. Bought it on Amazon, some German AV magazine brand.

It works fine most of the time. Sometimes there is no signal and it needs disconnected, switching sources etc.

The only thing I've not managed to get it to 4k properly is the ps4 pro.

There are some cables out there that guarantee the full 4k signal at 10m plus but they are expensive.

If I was in your position I'd buy whatever works properly and also run cat 6.

Be interested to hear if people's thoughts of key differences between 1080p and 4k.
