Question: 4K on VW570ES with Xbox Series X

Morning all

Hope I'm posting this in the correct place - there are a number of possible forums I could post it in!

I'm attempting to set up a home cinema system with Sky Q and Xbox Series X as the main inputs and a Samsung QN95A and Sony VW570es as the outputs. I have most of it working well (via an AV Access Matrix switch and an HD Fury Arcana audio extractor - although that is not relevant for this question!) but can't get the Xbox to play nicely with the projector.

The problem: when wired directly to the VW570es (i.e. ignore the setup discussed above) the Xbox detects a 4K display supporting 60Hz but if I switch the output resolution to 4K it doesn't actually display anything and I then get a message saying 'there seems to be a problem displaying 4K'.

My question: does anyone out there use a Series X with a VW570es? Is there a setting that I'm missing somewhere that will get them to play nicely together in 4K?

My current thinking (for what it's worth):
  • Sky Q displays UHD content on the VW570es with no issues, telling me the output is 3840 x 2160. This suggests to me that there is not an issue with my cables (e.g. that they can't carry UHD content) or with the projector overall. I have ordered a new HDMI 2.1 cable to test this just in case.
  • The Xbox Series X works fine with the VW570es when set to 1080p.
  • The Xbox also sends HDR 4K signals to the QN95A with no issues.
  • My tentative conclusion is that either the Xbox doesn't work in 4K with the VW570es or I've got a setting wrong somewhere that is causing these problems. I've tried adjusting most of the Xbox video settings (e.g. refresh rates, HDR modes) with no luck. I haven't adjusted much on the projector.
In summary: I'm interested to know if anyone out there has the Series X working in 4K with the VW570es and, if so, what settings they use and whether they ran into similar issues!

Thanks in advance for any help - much appreciated.

Simon

PS For what it's worth I've been pleasantly surprised at how well the AV Access Switch + HD Fury Arcana works with controlling multiple inputs and outputs. Happy to discuss if anyone is interested!

I appreciate this might be a basic check you’ve already carried out… are you 100% sure and have verified that the HDMI cable you’re using is 18gbps capable?

This was my first thought too as the cables were installed by a contractor and I'm not 100% sure what they used... is there a way to test the throughput of the cable without buying a specific HDMI test kit?

That being said, I'm working under the assumption that since Sky Q works in UHD the cable should support 18 gbps... is that a false assumption? Does Sky output less data than the Series X?

I have a new cable arriving tomorrow that will provide the answer to this point for once and for all.

yep... xobxone X has a cable test built in... am sure the series X has the same ?

depends on signal format and bandwidth... quite possible IQ wont push limits way series X can. Series X can push upto 48gbps I believe !

depending on length of cable there are certified cables you can buy and affordable priced...Premium certified, i wouldnt get anything without a QR code that can be verified with the hdmi.org app.

Sky Q outputs 3840x2160 in 10bit colour using HLG, but only at 4:2:0 chroma (@50/60hz) so that will fit down an hdmi 1.4 bandwidth cable fine (10.2Gbps). The Xbox on the other hand will be trying to send 12bit 4:2:2 @60hz which needs a full 18Gbps capable cable and connected equipment.
Make sure your projectors hdmi ports are set to Enhanced Format and if that doesn't fix it, then it is highly likely your cable is the culprit.
An easy way to verify that, is to limit the Xbox to 30hz or below (if you can) and if it passes a picture then, it is definitely your cable.

'when wired directly to the VW570es' - would suggest a cable issue.

'I have ordered a new HDMI 2.1 cable' - they don't exist, cables are either Certified or non certified which is different from HDMI Version numbers.

You don't say how long the cable from the kit to the Projector is - anything over 5m and you will want to consider a Fibre or Hybrid Fibre solution.

The HDFury Vertex²+Arcana work well as a pairing - likewise the upcoming Vertex³ (VRRoom) looks like a good option.

Many thanks for all the helpful advice on this. An update:
  • 5m '8K Ready' HDMI cable (appreciate from Joe's reply this may make no difference!) works
  • However 5m 'builder's' HDMI cable also appears to work - I can't recreate the failure
  • And, most interestingly of all, the 10m 'builder's cable' appears to work when I remove the HDMI socket that they had installed and plug the cable directly into Xbox / Projector
A couple of questions:
  • Is it plausible that the socket was causing the issue? I had assumed it was a straight passthrough
  • Am I OK to stick with the 'builder's cable' given that it appears to work or should I get them to rectify it for a higher quality cable? I'm reluctant to have them tear the ceiling apart but equally better to do it now than in 5 years! The cable they have used is 'Labgear High Speed 10.2Gbps' and states 1080P at 60Hz - but appears to work in any case.
Joe - one follow up for you too - will I see a benefit from using the Vertex2 rather than the AV Access Switch given that the latter seems to work? I was tempted by the Vertex2 given how well the Arcana works but the difference in price put me off!

That’s good news. I guess you need to ask how disruptive the works will be and if you’re convinced there are zero issues with pushing 18gbps continuously for validation.

If convinced, will you be needing greater than 18gbps on any end display device in the next 5 years?

Can’t be too much help on the socket front I’m afraid. I’ve always avoided face plates and hdmi couplers due to the issues you describe. Simple brush plate works well for my HDMI exit point.

Yes, it is plausible the socket was the issue. My advice is to put the highest quality cable you can in the wall with the highest capacity, so you don't have to dig it out again in the future.

The Vertex 2 also gives you the very handy side effect that it facilitates DV (LLDV) viewing on the projector.
I can vouch for how well that works personally. :cool:

'Is it plausible that the socket was causing the issue? I had assumed it was a straight passthrough' - as DB9S suggests yes very plausible that simply inserting the addition two connections points into teh signal path can cause an issue, like others we tend to avoid terminated HDMI plates where possible.

'Am I OK to stick with the 'builder's cable' given that it appears to work'
- Yes and simply ensure whatever cable you install can be easily replaced without major disruption at a later date.

'will I see a benefit from using the Vertex2 rather than the AV Access Switch given that the latter seems to work?' - if the current switch is working and that is all you require then stick with it. As DB9S highlights there are additional features of the Vertex2 which you may wish to enable which will have a positive affect on your projected image.

Thanks for the continued responses - apologies, I hadn't realised there had been so many!

Posting a 'final' update in case it helps anyone else out.

Given that the Arcana allows me to scale the output image, I was able to test the impact of the cable in the wall (10m, '1080p60') vs an external (5m, 'UHD capable') cable.

In summary, the 'UHD' cable works at every resolution available on the Arcana (up to 4K60 444 8b LLDV), although the highest output signal I got to the projector was 4K60 420 10b HDR (I assume because the projector doesn't support anything higher than that?).

The 1080p cable drops out above 4k60 420 8b HDR. This shows as 300 MHz bandwidth on the Arcana whilst 4K60 420 10b HDR shows as 370 MHz - I assume the cable is limited to around 300 MHz.

Both cables work when plugged directly into the Xbox (i.e. without the Arcana in the path) - I assume the Xbox is scaling the output appropriately for the cable? I'm not clever enough to work out what resolution / colour space the Xbox is outputting in both scenarios but I assume it's lower with the longer cable.

Interestingly (to me anyway), one of the faceplates appears to work with UHD signals whilst the other doesn't - despite being exactly the same device in principle. I take that as another warning to stay away from them!

Joe / DB9S - based on your comments above I can see a Vertex2 being ordered in the not too distant future! (Out of interest does this replicate the eARC feature of the Arcana? One of the reviews I saw suggested it does but it's not clear to me)

We will look to run new, higher bandwidth cables (that we have pre-tested!) if we can get the contractor to do it at a sensible price... we will see!

And a final word of warning: my contractor had originally wired up a different HDMI cable to one of the faceplates that they labelled as going to the projector. I had a PC hooked up to this (as an output) and plugging it into the AVAccess switch (also as an 'output') caused absolute chaos with the setup (dropped connections, etc) as well as making it look like one of the projector cables didn't work at all. Note to self: pay more attention to what the contractor is doing next time!

Make sure your hdmi ports are set to Enhanced Format on the projector to enable 4:2:2 12bit HDR.
See here for Vertex 2 info (earc is mentioned):

If you’re considering a Vertex2 at this time you may wish to look into the Vertex 3 (VRRoom) It’s due ‘soon’, although overkill currently in your setup it might not be too large a price differential and gives a bit of future proofing, if that’s of interest.

You can combine the HDFury Arcana + Vertex² (or Diva if you require HDR to SDR) and retain eARC/ARC capabilities - see diagram.

As CaroleBaskin suggest the Vertex³ (VRRoom) is also an option (available to pre order) if you require Features the Vertex² does not support.

It’s relatively cheap to test to see if it’s the cable but my gut feeling is it’s a cable issue, if you order from Amazon an optical HDMI cable you have a return refund policy is doesn’t fix your problem.
