Moving to 4K - cabling questions

[T1berious]

Hi I'm hoping someone here can help me.

About 4 years ago I did my Home Cinema install. link to my current build Home cinema DIY

The time has come to look at going 4K \ OLED which will mean going new TV, Amp and UHD Player.

The question mark is around my existing cables, 4 years ago they were labelled as HDMI high speed (I basically got the best[/] I could get at the time) but I'm nervous about them not being 4K ready. I've read a few threads saying try it and see but are there any HDMI cable testers that can take the mystery out of it?

Cheers for any advice,

'are there any HDMI_cable testers that can take the mystery out of it?' - your UHD_4K Source is a perfectly good 'test'!

Length is the killer - any properly certified High Speed cable up to around 6m ought to be fine with UHD_4K.

Lol, yes agreed, but I haven't purchased that yet. I was toying with getting a mate to bring his 4k TV up and then thought "that's ridiculous!"

Truth is I don't want to chase the wall again but as you've kinda said "high speed should be OK" and everything I've read on the magic that is the internet is pointing to 27Gb HDMI cables as snake oil.

I'll roll the dice as my cables in both Installations are not longer than 6 meters!

Cheers for your reply though!

UHD_4K - we find High Speed is reliable up to 6m with most designs, 8m is reliable on some of the older 'hose pipe' cables we have from BetterCables.

UHD_4K - anything over 8m we go with Fibre Optic.

HDMI 2.1 - has a new 48G cable spec, those reportedly top out at 2M!

Snake Oil - lots of that in the world of HDMI and HDMI cables.
