I am the unfortunate owner of a house which doesn't have room for any AV gear near the TV location. 

 

As such, it's now in a hallway cupboard about 10m diagonally away from the TV location, and houses all my AV/networking hardware. Note: Things take up WAY more space than one might imagine...

 

Anyway, before we moved in I bought a 15m long HDMI cable and tested it for a few weeks and it appeared to work fine at transmitting a 4k 30Hz 4:4:4 signal the full distance. We moved in and I ran it through some underfloor ducting and I now have some issues. The cable causes frames and or audio to drop anywhere from every few minuted to once an hour. Whether this is from interference from other cabling (power and ethernet run nearby) or a faulty cable I just don't know. 

 

After doing a lot more research than what I had done before I bought the HDMI cable, I have found 12m is about the limit for HDMI 4k signals to work reliably... 

 

So i'm now at a cross roads. 

 

I can buy another HDMI cable and try it out/my luck and see if it can make the distance. Or I can give up on HDMI altogether. There are a few HDBaseT 4k extenders available which should do what I want, but i've never used any HDBaseT gear, nor can I really find a whole heck of a lot of info/reviews. 

 

What are peoples experiences with HDBaseT hardware at home? Gefen and Atlona do some nice newer spec hardware which support HDCP2.2 and HDMI2 but are in the region of ~NZD$500-$1000 landed so do cost a bit more than an HDMI cable...

Try this cable as it is rated @ 18Gbps for 4K@60Hz (UHD ready).

BJC Belden Series-1 Bonded-Pair cable should work as well

Gefen also makes a cheaper Extender that is 4K UHD ready.

I will either be deploying HDMI fibre optic from Celerity or Ethereal HDM-GA1 with one of their passive cables.

ps - 4K@60Hz for UHD is a pain in the butt when it comes to cable because any brand and series cable can easily also reject one of your sources too. It's a matter of simply trying and seeing which one works.

 

 





Do whatever you want to do man.

I bought an HBaseT splitter and an extender from monoprice and it works really well.   Something like this ...

4K is new, perhaps you could buy something like this and wait for the 4k price to drop?  Depends if you really need 4k now.

 

One tip -- only ever buy 1 cable solutions (some require 2 cat cables).

A word of caution, "read all documents with extenders!"

Many only allow 10.2Gbps, which means 4k at 8bit only.

You will need 18Gbps to run 10/12bit which is where 4k is heading.

HDMI cables, the Monoprice active Redmere chipped cables have been recommended to me by my US video processing company as the ones they prefer to use for 4k duties. Look for 18Gbps.

I got some pricy (for me) 30 foot cables that said they were sweet as for 4k 60 - still get the odd glitch on it, usually a line or 2 flash up, sometimes a brief part of sparkles. Thats from a nvidia 970 to my oldish LG TV which only seems to do 8 bit 4k (not sure which end limits it) so I doubt it would work well at the higher depths if something did them.

 

it is just so iffy and unreliable. Its like when 1080p first became a thing and there were so many junk cables that couldnt do it.

Yeah, my fear is that I start buying HDMI cables and find none of them work and i'm in the hole for several hundred dollars and STILL have to find a suitable solution. 

 

Maybe I'll try the monoprice cable (although it still gets mixed reviews from what I read) and just cross my fingers.

Get a cable with the  Ultra HD Premium certification, http://www.bluejeanscable.com/articles/premium-hdmi-cable.htm

 

Even the Monoprice redmere have failed at lengths in excess of 10m, apparently there are new Redmere chips coming to handle 18Gbps at these lengths.

 

I've currently got a Monster UltraHD Black Platinum at 15M working fine, according to them its rated for 27Gbps (but not certified). Got it during a groupon special.  First time I've seen the Monster name live upto the hype :)

Cheap HDBase-T products can be problematic, much like the cheaper HDBase-T products.

 

Power supplies seem to be an issue... however there are brands like Gefen and BluStream who have reputations worth looking into.

I use a 15m dynamix hdmi cable and don't see any issues with it.
But I'm probably not that picky, but I would like to think I would see missed frames etc. Only $40-odd, reckon it would be worth a punt!... pb tech stock them BTW.

I have mixed result with the two Dynamics cables I installed... (1080p)
Interestingly the new Sky HD+ box works flawlessly on both cables and any channel on my Sammy Smart TV, but the Sammy BlubRay player just will NOT work on either, though works fine when connected close up on a 3m cable :(

Thinking perhaps different boxes have different output strengths too?

Are you pushing 4K 60FPS 4:4:4 through it?

 

Or 1080p?
