4K HDMI CABLE

Recommended Posts

Hi all,

I bought a new 4k cable early this year but only now got my electrician to install it as he was doing other work in the celling for me its 9m and goes through the wall into the celling.

 

SlimRun AV HDR Cable for HDMI Enabled Devices, 4K@60Hz, YUV4:4:4, 30ft...

I wasn't getting any picture last night and noticed a tag on one end saying source and one end saying display, installer didn't notice it. Are the new fibre optic cables all directional and wont work the other way around?

Any info would be greatly appreciated!

Yep, they're directional - no hope of it working in reverse, unfortunately.

Thanks Quark, thought that might be the case. Ok will have to get him back to swap it around!

For what it's worth there is a chip built into the HDMI cable send end which is powered by the HDMI connector on the source device (player or home theatre receiver) , thus it won't work in reverse. That's assuming it works at all as was the case with a so called 4K cable I purchased. Probably a good arguement to try the cable before it's put in the wall.

Thanks David,

 

Yes good idea I will try it first.

HDMI Fibre cables are normally marked source and display on the plugs, some like Ruipro have a large sticker inside the display box saying so.
