Needing a new HDMI cable my current in-wall cable is not cutting it.  I'm now looking at this cable RUIPRO HDMI Fiber Cable 10m has anyone had any experience with these cables.

 

Thanks

How can a cable not cut it? It's either working or not don't get sucked in by this HDMI cable is better cause of gold plated pins

HDMI is a digital signal. You'll get the exact same performance out of a $20 cable on Aliexpress or Ebay. Don't waste your money on an expensive cable.

I got one of these 10m Dynamix cables. Works perfectly at 4k60.

 

The cable is quite thick though, I'd guess 9 or 10mm and not that flexible so I don't know how suitable it would be for in-wall runs.

They are not all the same, try putting 18 gigabit down the cheap one and it will either not work or you will get a crapload of sparkles on it.

 

 

 

Saying something works at 4k60 is meaninless if its doing 4:2:0 over it, that is nothing compared to the HDR modes.

I haven't used the fibre hybrid cables, but I am firmly in the camp of 'buy it - forget about it'.

 

Fibre is the key!

 

I wouldn't run an HDMI over 7 meters, over that length I'd go with a HD-BaseT, but of course that's limited to around 13Gbs due to the restrictions of Cat cable... whereas fibre / copper hybrids can push more data down the pipe, are easy to run due to their slim cable and slippery jackets. What's more you don't have to add extra boxes or power plugs to an already crowded AV install.

I have the Murideo Fresco Six-G and Six-A test combo which is able to test bandwidth errors by bit count and also find loss of signal limits.

So far I have found 1 10mr cable that did not send anything beyond 576i for which I suspect moisture damage internally.
I have found a number of longer than 5m cables(uncertain of lengths when buried in walls) which break down around 10Gbps, and I note they were typically specified as high speed 10gbs

This means the client max is 2160p @ 24hz 8bit 4:2:2 and sometimes 10bit. Sometimes when at the max the signal gets lost between devices and the EDID fails and or the HDCP fails and screen goes blank. I also find leaving devices on auto can sometimes help as they self test and find their own limit.

Note: 2160p@24Hz 4:4:4 10bit is calculated to be 11.14Gbps, this is why longer reaches break down when they are rated about 10Gbps. The 5m and shorter cables I have found to mostly ok, despite the 10Gbps rating.
I have heard from a hardware video processor developer that shorter than 1.5m cables can have problems, not for the cable but the devices as they can get swamped in signal that is being over powered from the source. But I haven't seen that myself yet.


One main problem for some, especially those whom are from gaming, struggle conceptually with movie material running at 24hz.
But I remind everyone, if the core material on the disk or source is at 24hz then send 24hz. This means you can up the bit depth which is far more important than hz/fps. The display does the Hz up-conversion, unless you have higher quality outboard processors. Higher bit depth means better gradations and less potential banding.

If the source is 50/60Hz, then you may be best to send native, however note the bit depth is native at 8bit and the chroma will be 4:2:0 to be under 10Gbps, Chroma at 4:2:2 or bit depth and it with be 17.82 Gbps. If you have handshake issues or other image oddities then you may be running into signal errors.

Also keep in mind plugs and sockets can wear, moisture and dust can corrode contacts plus gaming consoles have more working on the plugs and cables adding wear on contacts.

I have not tested any optical HDMI yet so can't comment on the OP choice.
All I say, run conduit, and Ethernet.

Note, the new HDMI over Ethernet devices can do HDMI 2.0 now up to 70m.

4K and length is my problem.

The current cable is 6m in wall and + 1m  from wall to receiver has no problem for 1080p, maybe the odd drop to a black screen for 2 seconds once or twice a week. But that could be the sky box, I don't see it on any other source.

Sure for 1080p but 4k at 7 meters? as 4K is where my problem is.  I wouldn't disagree with the cables doing the interconnect between the source and the receiver i'm using dirt cheap cables there.

 

 

 

My XBOX one X works fine for 1080p but wont switch to 4k (Bypassing receiver, before you ask) Works fine when connecting directly using a short cable.

Can you recommend a device?
