    SkyQ question...

    SkyQ question... 4th Oct 16 at 11:41 AM
    I've just had SkyQ installed. I have an HDMI lead and a ethernet cable buried in the wall. The HDMI lead I have buried isn't strong enough to take the 4K feed so the picture jumps. We've had to put a 4K HDMI lead on the outside of the wall but it looks messy.

    Does anyone if you can push a signal through the ethernet or is there any other solution or am I looking like pulling the plaster off the wall.....

    Thanks in advance

    You can get adapters to transmit HDMI via Cat5e/6 cables

    Most only rated to to 1080p signals for around £40 mark
    https://www.amazon.co.uk/Extender-Ethernet-connection-transmitter-compatible/dp/B01A0QYG4O

    For 4K signals then the price jumps to nearly £180
    https://www.amazon.co.uk/Extender--Full-Single-Cable--Sender/dp/B01HZDY7Y4

    You might be able to find cheaper options.

    Or pulling out the wires Inserting conduit and re plastering might be cheaper in the long run

    That's great, I'll explore those options and probably dig out the chisel!

    Appreciate it. Thanks

    HDMI either works or it doesn't and there is no such thing as 4K HDMI.

    If you're going to bury cables, you really should be putting them in some sort of conduit, preferably with a draw string.
    Change is inevitable, except from a vending machine.

    Unfortunately there is a difference. HDMI wont work (properly) and you need 4k compatible cable

    You either have a faulty cable or something else is wrong.

    Have you tried a new cable and does it fix the problem?

    Correct. I've put a "4K lead" and it works perfectly and tried two "standard" HDMI leads and it jumps.

    From the same cnet link above...

    Just because a cable is called high-speed, it doesn't mean it actually is. Some cheap HDMI cable manufacturers might just throw the label on a cable that can't actually handle the data or that can't handle the data over long distances. In this case, the cable won't work with 4K (this is true with 1080p as well, btw). This does not mean that all cheap HDMI cables don't work with 4K; it only means that cheap HDMI cable doesn't work with 4K. Get a different brand of HDMI cable, at the same price, and it will likely work.

    Anyone saying all HDMI cables are all the same because it's 'digital', and that all HDMI cables are the same, is wrong. This thread is proof of that. Look up 'bandwidth'.
    Nothing wrong with starting with a £1 HDMI cable, though...

    There are 2 types of HDMI cable.


    HDMI and HDMI 2.0


    The former doesnt have the bandwidth to handle 4k video, the latter does.
    Most cables sold these days are of the 2.0 flavour.


    I guess you could call these 4k HDMI cables

    Again wrong and misleading.

    There are a number of HDMI "standards" with HDMI 2.0 being one of them but an HDMI cable is an HDMI cable. Some have gone through testing to prove that they can work with 4K and therefore can put that on their packaging and no doubt charge an arm and a leg whilst there are plenty of others that haven't and still may (or may not) work with that standard.

    Sorry, you're wrong on this one ...


    Standard HDMI Cable: 1,782 GBit/s (74,25 MHz × 8 bit × 3, Type A)
    Highspeed HDMI Cable: 8,16 GBit/s (340 MHz × 8 bit × 3, Type A + C)


    Although it is really only a matter of symantics as like i said, most HDMI cables you can buy now are "high speed" and you certainly dont need one that is branded as "4K".


    I guess the OP installed his cable back when HDMI 1.0 was out, hence why it cant handle his 4k stream

    It is symantics. A high-speed HMDI cable is only called so because it's been tested to deliver that speed. I could go out and purchase an unbranded £1 cable without any specification attached yet is still may deliver the same performance.

    Yes, it most likely will because like i said, most cables available on the market are now 2.0


    There is a difference in the 2 standards that i have provided above.
    So for you to say there is no difference, and that a HDMI cable is a HDMI cable, is wholly incorrect

    What are the HDMI certifications?


    Cables are rated by speed, There are only two certifications: The original HDMI 1.0 Standard cable, designed for the first HD transition, so 720p, 1080i support, which are very rare now.
    Any cable that claims to be high speed must support the full bandwidth.




    HDMI 2.0 makes the signaling method more efficient, That means that existing High Speed HDMI cables, which should always be labeled as “High Speed,” both on the packaging and the cable itself, can handle 4K content at 60 frames per second. If you’re buying a new 4K TV and you already have a High Speed HDMI cable, then there’s no need to buy a new one.

    There are actually 4 types of HDMI cable, not 2.

    Standard (Category 1)
    Highspeed (Category 2)
    Standard with Ethernet
    Highspeed with Ethernet

    The Ethernet versions have an additional channel.

    Despite what people say, better quality cables, can make a difference. But mainly just in the length of the cable that will work. It doesn't make a difference to visual quality
