HDMI 2.0 cable can handle 4K at 50-60 frames per second v1.4 can only handle 24 frames/ second. Google is your friend....

But the version numbers are applied to devices. Cable ratings are different and involve categories like standard speed and high speed.

@steveo73: Most existing HDMI cables should handle it. What device are you trying to play from? It's more likely that the playback device can't handle the files than the cable being the problem.
As mentioned you need to use HDMI 2.0 cable. However, you need to check that your TV supports HDMI 2.0.

HDMI 1.4 only supports 4K at 24Hz.

As mentioned you need to use HDMI 2.0 cable


As mentioned there's no such thing. HDMI 2.0 is a device standard, not a cable standard. Cables certified by the HDMI standards body are even explicitly banned from advertising a version number:

I had assumed that the standard speed HDMI cable was for HDMI 1.4 and the high speed HDMI cable was needed for HDMI 2.0.

Mag box



I've never used one. But you've checked settings and switched it to send out a 4k signal?
I had an android box that didn't automatically switch up to the right resolution output.

Most cables should give a 4k signal at either 30fps or 60fps, so you should be getting 4k picture either way.

The content you're running definitely 4k?

Apparently Yh tbh I bought HDMI from Poundland so prob crap

Not all mag boxes support 4k. Probably best if you list the model number and specs to confirm if it's 4k capable. I would start with the link below and see if you can find out the model number.

Also check that the stream or media you're using is 4K.

I use poundland HDMI cables from a 4k Roku box, 4k Freeview box and PS4 Pro...no issues with 4k content whatsoever.

I'd hazard a guess it's more likely an issue with the source device you are outputting 4k from.

No, standard speed was for 720p HD but never got used much. The high speed specs apply to both Full HD and 4K but some of the earlier cables apparently had some technical issues with 4K so they created a new certification (premium high speed) to test explicitly for 4K, although not that many cables have been put though it.

What length of cable if it? Higher resolutions will only work on shorter cables, 5m or less is usually a safe bet

That box is 1080p tops. Hence why I posted the link.
That page makes no mention of 3840x2160 output support, and also doesn't mention the HEVC or VP9 video formats that most 4K video uses.

You need a MAG 351 or higher to get 4K support.
