PSVR will pass through 4K but not HDR to your 4KTV

So basically the box doesn't conform to hdmi 2.0a spec. Really stupid decision by Sony, I am still running 1080p right now, but will probably move to 4k eventually. This and the no uhd player are stupid decisions. And I have both on pre order so I guess I am an asshole contributing to the problem lol.

Neither did the PS4, but now allows HDR playback. I can't imagine the breakoutbox to be designed to be the absolute minimal tech required, so they probably have some wiggle room to perhaps release an FW update. Until then, it flawed

So the PSVR processor unit is basically used for 3D audio and putting the image on TV correct?

Would it be possible to just hook up the USB for the 3D audio and not worry about the external display, thus avoiding splitters or plugging and unplugging cables or is the HDMI to the PU required either way?

How would you get sound to the breakoutbox without HDMI cable?
 
I really don't think the whole splitter solution is going to work.

Even recent HDMI Matrices (dedicated multi input/output HDMI switchgear) have issues with HDR throughput.

In light of that, Sony's little box of tricks never stood a chance.

So while the whole switching cables thing is indeed a pain in the ass, the issue here seems to be that HDR specs are in flux and and compliance with hardware is difficult to nail down. Nothing Sony can do about that right now.

I think people are right to be pissed off, but I don't think it's avoidable at this time.

Yeah I guess my point is, why isn't a product that is coming out at the end of 2016 using the hdmi spec that is over 2 yrs old, just really shitty decision making.

Basically you do this and solved... and you need to change from "HDMi 1:VR social screen signal" to "HDMi 2:pS4 HDR signal"

Sony and VR is taking us back to the stone age of wires everywhere gaming.

Wires everywhere and low resolution screens for high premiums.
 
While I can see this as an inconvenience to some I will never understand the negative outrage. People are actually cancelling preorders over this? I mean really?

I also love how when PS4 Pro was announced everyone was like "I don't care, I don't have a 4k TV anyways." now everyone is like "What do you mean I have to switch the HDMI cable on my 4k TV when I switch between PSVR and PS4/Pro?!"

It feels like people are bitching just to bitch at his point.

Can't even get a 1080p TV with HDR on the market, now all of this just to get HDR functionality if you got a PSVR.... maybe it's not worth investing in HDR right now.

Folks thinking about splitters/switches, I don't think that's a viable solution at this point, it's going to add lag (regardless of how good it is), which is crucial for the PSVR. PSVR as it is, is currently standing at just under 18ms of input lag. Adding a splitter to the equation before the signal reaches the Processing unit, is going to increase that to above acceptable levels for VR.

Edit: Nvm, my perception seems to be based off receivers, and I just assumed that my active switch (that I use in my room) was also probably causing a slight lag that I just didn't notice for regular gaming.

Hopefully a suitable splitter is found before the Pro comes out. I know I would not want to have to switch cables every time I wanted to play with HDR enabled. That would kinda piss me off actually.

This explains why PS4Pro has an additional USB on the back.

Oh, I agree. Though I don't know why Sony went this route. It either has to be a technical/security issue with the HDMI spec, or a design oversight. I can't believe Sony would have gone for cheaper components (if that is the issue) if they knew this would be the outcome.

I don't think HDMI Switches add much lag, if any at all. There is no processing going on at the switch level, its sending the signal directly.

Edit: I should say if you use a simple switch. If you're using something that will improve the image quality (scaling), like what a lot of receivers do, then you might run into some lag.

To be fair, all that does is move the wire in the diagram from the front of the PS4 to the back (of the PS4 Pro). It won't reduce the number of connections required.

Passing through the PU and then passing through the AVR isn't what I would want to do anyway. I would just swap cables.
Are you suggesting to swap cables when using the PSVR so that it isn't routed through your AVR, and then swapping back to use the AVR when not using VR? I guess that would work.

You are misreading. This is for when you're playing a non-VR game that supports HDR when the breakout box is connected. The HDR signal will not be transferred through the box.

To be more clear, the breakout box is supposed to be always connected, even when you're not using VR. It will pass the HDMI signal through normally when playing a non-VR game. Unfortunately, it won't pass HDR signal.

I believe you need to plug into the breakout box regardless if you want anything displayed on your tv or not.

Ahh, got it. Thanks. :)

That depends on what data is stored in them. Majority of what gets used by real-time renderers isn't actually dynamic-range data - we've stopped baking luminance into color-maps a long time ago. Exceptions are things like sky-boxes, where usage of HDR data is fairly common.


Not to my knowledge, but it's still worth noting that because of the nature of how HMD displays are viewed (occluding all external light), and adding in the lens-optics, effects of brightness changes are quite different from conventional display viewing conditions (less need to achieve the same kind of luminance levels specified by Dolby standard for instance).
Obviously - expanding actual color range will still matter, but my point was that for most VR software, that'll be a simple patch away also.
Glad to read this and can see how the work on your end would be a somewhat straight forward patch software wise. Here's hoping for 2nd generation HMDs figuring out the proper solution hardware wise for that true 10bit HDR 'feel' in VR. It will be quite incredible will it not? Viewing that HDR enabled software that much more closer to your eyes has to be pretty striking if done properly.

I think he/she is saying that you don't need to output the video from the breakout box to the TV, so therefore you don't need use that HDMI cable. Split the HDMI cable from the PS4, one goes to the breakout box and ends, the other goes to the TV for HDR.

You would lose the social screen though.

The real problem might be that the splitter won't carry the HDR signal properly. In which case, you'll be forced to always manually switch cables when using a 4k hdr tv.

I guess I will have have two hdmi cables going to the PS4, and leave VR unplugged unless I'm using it. It's not like you can use VR without a physical set up process anyways.

Inconvenient, but so is vr.
 
This explains why PS4Pro has an additional USB on the back.

However, it makes clear why the breakout box should have been incorporated into the pro. It would have eliminated so many cables...

Imagine your current setup with PS4 where all you do is plug in the headset; because that is how simple it would have been if they incorporated the breakout box. No extra USB, no extra power cable, and no HDMI pass though (just 2 HDMI ports on the pro).

BTW, people saying it passes through 4K are wrong. It's 4K 4:2:0, meaning there is heavy color compression. That's not real 4K in my eyes at least and is unacceptable. What this means is the breakout box is only able to handle HDMI 1.4 signals, not the HDMI 2.0 that PS4 Pro can output. People using PSVR on a 4K screen with a Pro should not run their 4K outputs through the VR breakout box unless they really don't care about the downgrade quality. I really hope someone finds a good HDMI switcher to solve this issue. Not sure what is out there that isn't too expensive.
 
Are you suggesting to swap cables when using the PSVR so that it isn't routed through your AVR, and then swapping back to use the AVR when not using VR? I guess that would work.

Yep. I would just connect the PU directly to the TV and leave the AVR input alone.
 
WTF @ that picture. I always knew PSVR involved a lot of wires, but wow that puts things in prospective.

Speaking about perspectives, this is the same pic (incl. the HDMI switch), but without the power supply cables.

EDIT, plugged into a PS4 Pro ;).

lol @ everyone trying to make this about the number of wires. It really isn't that bad. Most of the ones picture you're already using.

Always gotta find some way to complain.

PS4 output 1080p+HDR, HDMI 1.4 is more than enough bandwidth to cover that. 4K + HDR require HDMI 2.0a.

4:4:4. This refers to color sub-sampling. Whilst 4:4:4 is used in content mastering, UHD is distributed via 4:2:0.

I don't believe there are any (console)games (so far) that use 4:4:4 but I might be wrong on that actually makes sense.
 
Uh, wow. What an oversight. That's such a ridiculously dumb thing to overlook that I'm almost hesitant to buy a VR and a Pro. Guess they're competing products more than we thought. Not complementary at all.

Annoying and definitely not elegant this hack job is turning out to be. Still there Day 1 though for both vr and the pro.

Ugh, so many design flaws XD

Needing the front usb port.

That splitter thing that either you change the cables every time or have to deal with a splitter with also has its own share of annoyances.

Separated cables for the headset and the head phone, why? Don't tell me the psvr doesn't come with a headset and you have to use one yourself? Can this at least be wireless?

What would the pro improve on that scenario? Or that's already the pro?

PS4 Pro has a USB in back, so no front connection required.

This really smacks of one hand not knowing what the other hand is doing... hopefully they can remedy this via a firmware update but with the recent push of HDR to all PS4s and it being a key highlight of the PS4 Pro reveal, I can't imagine Sony will just leave it this way... going "all in" should get you premiums, not trade-offs.
 
I just assumed you would unplug it if you weren't going to play a vr game. What am I missing here. Is it a big deal to not having HDR passed through the VR headset?

Yup. I'm going to have a second HDMI sitting right next to my PS4 that I can easily swap back and forth with the one going to the breakout box, which I was going to have to do anyway since my receiver does not support 4K nor HDR so I need one going straight to the TV anyway.
 
I'm surprised by how upset people are about this... is it really that big of a deal to change the hdmi cable from the back of the ps4 to the breakout box? And if it is a big issue, why not just buy a $20 splitter. I mean I certainly wouldn't go as far as saying this is a huge oversight or garbage or whatever. It only takes as much effort as putting a disk into the system doesn't it? In the worst case, if you have your console tucked into a cabinet, you could just get a small hdmi extension so that you don't have to reach around or turn the console around. Sure it's inconvenient, but it's not that much of a game changer in the long run.

People like convenience. This is pretty silly. No one should buy gen 1 vr anyway.
 
What kind of connections does the PSMove have?

Im just wondering cause it sounds like one console is going to basically destroy my nice neat cable management

This is one of those threads people needs more reading comprehension.

Isn't the breakout box supposed to be one of those things you setup once and not have to worry about again later? If you don't use VR, to me it looks like things should still work as if you had your ps4 connected directly to your TV. So what exactly is wrong with what farisr said?
 
Wow, now that's a schoolboy error from Sony. Very surprising for a company which 'specialises' in AV equipment.

You have to get this simple stuff right, the general market doesn't spend their time on the internet finding out all the titbits like this. They just expect things to work, and this should have.

Maybe they can firmware update it or something?

Bluetooth wireless for use, mini-USB port to charge or you can use one of the many charging stations including some of the new ones coming.
