    Hello everyone, I'm having trouble getting a signal from my Xbox one s when I set my Sony TV to enhanced hdmi mode. My hdmi leads are 17.8Gbps but Sony's website states I need 18Gbps, is it really that simple?

    'My hdmi leads are 17.8Gbps' - in reality those figures mean very little.

    The only 'Certified' labelling for HDMI cables is from HDMI.org and those are Standard, High Speed, Premium High Speed and Ultra High Speed.

    HDMI :: Manufacturer :: HDMI 1.4 :: Finding the Right Cable

    How long is your installed cable - that is usually the crucial 'specification' with 4K UHD signals?

    HDMI cables - sometimes very short cables can cause some devices a problem.

    XB1S - try connecting it direct to the Sony TV and see if that works in terms of the image and the settings you are aiming for.

    Does your AVR support UHD at 18GBs?

    I'll try connecting directly to the TV and report back, regarding the AVR I'm not sure if it supports uhd at 18Gbps and I can't find anything online about it. My Apple TV works fine though?

    I just tried using a different hdmi lead, same make & length but I'm unable to take the lead from the AVR straight to the TV so I had to use another lead. It worked fine, I then plugged the Xbox back into the AVR and that also worked. Am I looking at possibly a faulty hdmi lead?

    HDMI cable - could be 'incompatible' rather than faulty.

    HPD (Hot Plug Detect) - sometimes making the 'direct' connection initiates the required handshake between the two devices and once they have made that initial handshake they are happy to get on with it on subsequent sessions even with a Repeater (your AVR) device in the signal path.

    Now it s working 'don't touch it' :)
