hdmi 2.0 cable

right i thought this would be easy to find a cheap 5 metre hdmi 2.0 cable (capable of 3840x2160 @60hz) seems not auction sites are turning up people claiming they are 2.0 but read further into the listing they are clearly version 1.4.

cheapest I've seen for 5 metres at the minute is £60 am i just being incredibly stupid or are they really this expensive. My new TV comes Tuesday and i want to try out 4K gaming from my rig and see what it's like but from what I've researched version 1.4 is only capable of 30Hz and only 2.0 is capable of 60Hz

The TV has not got DVI or display ports so that is not a option so has to be HDMI.

I bought 2 of those one for my UHD Bluray and one for skyQ, and they work perfectly sending HDR to the tv just fine

just what i wanted to hear

thanks for chipping in

are they heavy? i'm wondering weather to order the 10 metre cause 5 is a bit tight if they aren;t very flexible

Your existing cables are likely fine. If you had done your research properly you'd have discovered that cables don't have HDMI versions.

As long as it's rated high speed then you're fine.

I'll test the theory tomorrow I'll pit my old high speed with ether net against my new ones

I found the >5 year old hdmi cables I had from supermarkets for 1080p connection to tv, were evidently slow speed since both of them dropped out the link to a 1440p@50 monitor every 30s or so - that was when i bought a new fast cable.

The article did not seem to reveal what was the innovation enabling sending 18Gb/s 4k - 2160p@50/60 down a cable that only had to send 10.2Gb/s under hdmi 1.4. ...

OC , our host, themselves have some 5m flat heavy hdmi cables - with even light weight hdmi cables I only let the horizontal tv connector support about the weight of 30cm of cable vertically, before i support/tether it.

apparently from what i can see 1.4 can only handle 4k at 24-30HZ whereas 2.0 can do 4k at 60HZ i'll be testing this tomorrow if i can get everything set up.

so theory tried, the 1.4 cable tried it's hardest to achieve full frame rate on the phantom pain at 4k but stuttered massively and dropped the signal quite often, tried the amazon 2.0 cable and managed to get full frame rate which ranged from 45 ro 60fps depending on the scene. I have to say the phantom pain on 4k on a 50 inch TV looks gorgeous, must have been good the missus said what you watching i said i'm not i'm playing a game LOL

this made great sense, i think the market is flooded with cheap cables tht simply don't meet specification but claim they do

I used to believe this, I used to tell people who spent more than £10 that they're wasting their money. But now, I'm not so sure this is true.

I am trying to drive an OLED 2160p display @ 60hz with 4:4:4 chroma with a 3m cable (so cable length not the issue).

I went through 13 cables, all were labelled 'High-Speed', 'HDMI2', 'Latest Standard' and all that blurb. I tried everything from a £5 Amazon Basics cable to a £100 cable and everything in between.

10 of the cables simply produced 'No signal'. 2 of the cables did sync but every once in a while (maybe 6-7 times a day), the display would flicker a few times. Only one cable worked. One. And unfortunately it wasn't the Amazon Basics one!

So whilst I agree that if you're just after 1080p, then really, it doesn't matter - any cable will do. But if you're more towards the high-end, don't bank on a cheap cable. And if you're going to put one in a wall, make damn sure it works first!
