Wireless hdmi

My fibre optic cable running from the amp to the projector stopped working recently. Long story! (This was run in the ceiling when I was having work done in the house a few years ago.)

I had run 2 cat6 cables when I had the work done. I've tried a cat6 to hdmi converted and it sometimes works but the problem I have is it's not stable. The screen flickers sometimes and at other times there is no image at all and I've got no idea what's causing it.

I want to try a wireless option. Any suggestions? I'm happy to pay a premium for reliability. The distance is 4m with no walls in between. (There may not be a clear line of sight though as the amp sits on a shelf with a door. The door has 4 six inch cut outs and is covered in 2 layers of AT fabric.)

Thanks in advance for your suggestions.

How long is your run and do you have access in ceiling via an attic space? Can you install a new cable? Did you use a conduit for your cabling?

Depending on what kind of CAT-6 cabling you used, solid copper core (non-CCA/CCS) or pre-terminated CAT-6 (ethernet cable) you may be able to terminate with HDBT.

Wireless HDMI, at least the last time I checked, was hit and miss, especially with 4k HDR.

The run is approximately 4m. I could get to the ceiling from the bedroom above but it means moving the beds, carpets, floorboards, etc and I'm not willing to do that. Didn't use a conduit.

What's HDBT?

My projector is a JVC x500 so not fussed about 4k HDR. (If I was buying a new project, native 4k etc, I would just access the ceiling from above as you've suggested or even take a part of the ceiling down and lay new cables and pipes etc for future proofing.)

We have another poster here who is well versed in all things HDBT. Hopefully @Joe Fernand will respond. If HD (1080) is all your concerned with, then you connection is a bit easier. If you ever decide to move up to the higher video standards, then you'll seriously need to think about your connectivity,

CAT cable - ideally you would find someone with a decent quality cable tester to run a suite of tests and confirm that the cable and terminations are good, a basic continuity tester is not sufficient.

HDBT - is the industry 'standard' for HDMI over CAT. There are various silicon options which manufacturers can integrate into transmitter and receiver kit, Audio-Video Products - Valens.

A decent HDBT Extender set coupled with a reliable CAT cable will deliver a stable signal at 1080p or 2160p.

Wireless HD - is always best avoided unless there are no other options.

Thanks Joe.

I don't see that I have other options. I've tried the cat6/hdmi extender and it hasn't worked. If I'm going to take the ceiling down, I'd just run HDMI cable. I really don't want to take the ceiling down though.

Any recommendations for wireless HDMI products?

Which Extenders do you use - they are not all as reliable as each other, huge differences in quality and reliability between brands.

Wirless HD - my recommendation is to avoid it at all costs.

Look for an extender based on HDBT - drop me a PM if you want info on units we supply.
