Hi all,

I think I know what the answers are but just wanted to sanity check if I can please. Picked up an XBox One S in the Black Friday sales. Have a 4K Panasonic that's (until now) fed a signal from a PS4 via a HDMI into an amp (Doesn't support 4K if there's even such a thing) - and then a HDMI into the TV.

- Am I correct in thinking that I need to run the HDMI directly from the XBox into the TV to get the 4K signal as opposed to via the amp? I therefore need to run an optical cable from the XBox to the amp.

- if so, can I use the existing HDMI cable that's here (it's plumbed into some purpose built shelves) or do I need to run the new HDMI (it's labelled 'high speed' but I think that's marketing tripe) that came with the XBox.

Hopefully it's a simple plug and play with existing wires and minor rerouting as a digital signal is a digital signal??!

Thanks in advance.
Tuan

I would say most likely yes you will need to plug directly into the TV.

Looking at the Xbox One S specs it seems to be HDMI 2.0 so as long as you have either a 1.4 or 2.0 cable it will manage the 4k. 2.0 is best as it allows 60Hz instead of 30Hz.

Id just buy a cheap 2.0 cable if you don't already have one. No need to fork out for these stupid expensive cables labeled as "4k" etc.

No such thing as a HDMI 2.0 cable, please don't be fooled in to buying these.

Invest in a cheap high speed HDMI cable, Amazon Basics should do.

As long as its high speed, 4K HDR etc will work.

Ummm yes there is - taken from Wiki

HDMI 2.0, referred to by some manufacturers as HDMI UHD, was released on September 4, 2013.
HDMI 2.0a was released on April 8, 2015 and added support for high-dynamic-range (HDR) video
HDMI 2.0b is released and enables these key advanced features:[115]

Enables transmission of High Dynamic Range (HDR) video
Bandwidth up to 18 Gbps
4K@50/60 (2160p), which is four times the clarity of 1080p/60 video resolution
Up to 32 audio channels for a multi-dimensional immersive audio experience
Up to 1536 kHz audio sample frequency for the highest audio fidelity
Simultaneous delivery of dual video streams to multiple users on the same screen
Simultaneous delivery of multi-stream audio to multiple users (up to four)
Support for the wide angle theatrical 21:9 video aspect ratio
Dynamic synchronization of video and audio streams
CEC extensions provide more expanded command and control of consumer electronics devices through a single control point

I think those are the general specs for HDMI, i.e. for HDMI sockets, and the chipsets in them that do the decoding of the signal.

I think HDMI version number is also tied to the encryption protocol version as well (called hdcp).

I'm not sure there is a 2.0 2.0a cable etc. In thoery a "hi speed" cable will do but YMMV. 4K does mean being able to send a lot more information a lot more quickly, so some cables may nopt be able to cope. You'd hope that "4k" cables means they have been tested to be able to carry that signal but it will be hard to discern that from general marketing codswallop.

Thanks for the replies. Got things set up. Turns out the TV is 4K but no HDR. Have plugged directly into the TV and on the XBox it's detecting the 4K display (8bit/60hz) and I'm using the 'high speed' HDMI cable that came with it.

Having said all of that the visuals are decidedly underwhelming... I don't know if it's the lack of HDR or the TV calibration (used an AVForums set up). I'm playing Rise of the Tomb Raider which is supposed to be one of the better showcases for it but it's certainly no better than Batman Arkham Knight that I was playing at 1080p on the PS4.

Makes me want to go out and buy a new HDR TV!! biggrin

Thanks for the replies. Tuan

Surely the Xbox is just upscaling the 1080 game to 4k anyway, as I didn't think the Xbox One S games were 4k yet?

The one s doesn't do 4K gaming. The 4K is Blu ray or Netflix at the moment. So op is only seeing upscalled 1080p or worse.

Please read what I wrote, there is no such thing as a HDMI 2.0 CABLE.

HDMI 2.0 would be the version of hardware in the TV/ XBox etc. Cables do not have version numbers.

To carry a 4K/HDR signal, the device(s) need to have a HDCP 2.2 port.

AV Receivers prior to late 2015 will most likely not have a HDCP 2.2 port, and therefore won't be able to pass through a 4K/HDR signal.

If you have a compatible TV and new Xbox One S, but your receiver is out of date. One way to get around this is do the Xbox One S -> 4K TV and then carry the audio via Optical from TV -> AV Receiver.

In terms of HDR, true HDR colours need a TV with a 10-bit panel.
Normal TV's have an 8-bit panel which can't handle the same colour range.
The chances are a £499 Black Friday 4K 'HDR TV' will only have an 8-bit panel, which is misleading customers IMO.

If you are unsure on either of these, check:-
-Does your equipment have a HDCP 2.2 hdmi port?
-Does your TV have an 8-bit or 10-bit panel?

In terms of the content, the Xbox One S can:-
-Output 4K HDR Blu-Rays (pending the equipment is HDCP 2.2, 4K, and HDR etc)
-Output games with the HDR colour range, if the game supports it and the equipment does (note games are non-4K even though they are taking advantage of the extended HDR colours)
-I know that Forza Horizon 3, Battlefield 1 and Gears of War 4 supports the HDR colour range at the moment with more coming.

HTH.

I hate seeing people get conned in to buying silly epensive cables. I've seen big retaillers pushing HDMI versioned cables when in reality they just don't exists.

Hopefully this will help anyone who comes across this thread.

Nicely said.

The whole 8/ 10 bit scenario is very important. Retailers do not seem to advertise this. And I doubt many would know the difference.

Stick your TV model in to http://www.displayspecifications.com/

It will tell you the details you need.

I know all of this, as I've just totally modernised my whole AV setup, with 10-bit 65" Sony XD93, 2016 Yamaha Receiver, Sky Q etc etc.

Lots and LOTS of research.

However, the end result is:-
-4K HDR Blu-Rays look... INCREDIBLE
-Battlefield 1 in HDR looks stunning
-Sky Q 4K football is dreamy

if the a/v amp does not support 4k how would a 4k signal pass the a/v amp to the tv from the xbox??? it won't

my new A/V amp does support 4k so in my instance it will. so as said you need to go xbox to TV
