4K HDMI over 15m?

ssmacc · 13 Oct 2019 at 09:27

Hello,

I've recently updated to an ATMOS receiver and have noticed a few sound drop outs whilst watching 4k ATMOS films (@ 1080p), I changed the 1.4 HDMI cables to 2.0 and the drop outs to the TV have stopped.

However, when using the projector (20m 1.4 HDMI) the drop outs in sound still happen (maybe 4-6 in a movie, but only in high bit-rate, Netflix ATMOS movies via the XBOX are fine for example, 4k via the Nvidia Shield drop out)). Question is can the 15-20m cheap HDMI cables now handle 4k? I can fairly easily replace the cable and I'm hoping 4k@24Hz is doable (and thus the 1080p ATMOS that I require is)

I'm thinking of trying a 20m £30 cable for my needs before I try a repeater...good idea?

I ended up buying a 15m fiber optic HDMI cable so i could run my projector at 4k HDR.

Fibre-optic cables have come down in price and HDMI 2.0 cables can be had for under £50.

Thanks!

Based on the above suggestions I'm thinking of going for the below:

Good idea?

Thanks for the support, much appreciated.

Yeah a fibre optic cable will deffo sort it. I've got one running into a HDMI switch which then runs Sky UHD, Apple 4k tv PS4 etc.

Cable is - https://www.amazon.co.uk/UGREEN-Cab...fibre+optic+hdmi+ugreen&qid=1571069060&sr=8-4

Switch tried a couple and this one actually will do 10 bit 60hz without any issues:

I have three fibre-optic Displayport cables. These have double the bandwidth of the HDMI 2 cables. They're now £80 apiece.
