10m 4K HDMI Cable

[C3CTD]

Hi,

We have purchased a 8K fiber optic hdmi cable 10m,hdmi 2.1 cable 48Gbps Ultra High Speed and Channeled it into the wall ( stupidly we did not check it first!). The cable works fine for Apple TV but will not work with the SKY Q box.  Is this HDMI lead incompatible with the Sky Q box?

No reason why it shouldn't work really. If anything it's over-specified for Sky Q which is relatively old technology now. 

Make sure you have the direction correct as fibre optic HDMI cables are directional and can only be fitted one way.

I managed to get it working by changing the resolution to 1080p.  Very relieved as now don't have to channel the wall out again!

As you've discovered, a basic rule is 

a) test first

and 

b) where possible install in-duct with brush plates rather than plastered-in, particularly as plaster itself may degrade the cable sheath by chemical action.
