I read that you are still working on the technical details of the Pimax 8K X, so I was wondering if you considered an 8K X with HDMI 2.1 instead of two DisplayPort?
HDMI 2.1 should have enough bandwidth for the 8K X and be more future proof for people who want a single cable. It would require next gen graphics cards with HDMI 2.1, but people who want full performance will buy those anyway.
Or is it possible to develop an Adapter that allows to either use two DisplayPort or HDMI 2.1, so that users have the choice of using whatever the best option their graphics card has?
Finally, on an unrelated topic, there’s the risk of direct sunlight falling through the lenses damaging the screens of VR headsets. Have you considered using smart film as an automatic protection to block light in front of the lenses while the headset is not on the users face?
The problem is not the cable’s bandwith. One DP 1.4 cable is enough to deliver the 8k X all the data it needs. The problem is the bridge chip, that can’t handle it, there is no bridge chip available that supports DP 1.4 up to the highest bit rate. So first you’d need a bridge chip that would fully support HDMI 2.1. Next problem though would be, like you mentioned already, the gpu cards supporting it. I don’t think there currently are any ? And it’s still unsure if Volta is even going to support it. So I doubt this would be a good choice.
Of course you could always store it in a box or under a cloth, but you can’t always reliably control the environment, especially if there are multiple people handling the headset or you take it to a different place.
There’s a couple of people who had their headsets ruined by sun damage, who thought there would never be sunlight where they stored it.
Either way, I am suggesting an option that for a couple dollars could prevent a few hundred dollars in damage, if it’s feasible to implement. That’s definitely at least worth exploring.
Your entire argument is basically like saying “Just drive carefully, what do you need a seatbelt for? Humanity …really…”
might just put a cover on it or something in that case, seems easier and more cost effective if its really that big of a problem. cover 1mm plastic black shaped or make it yourself.
Didnt know it was that big of a problem since i never store mine in daylight anyway.
I dont like dust get on the lenses so. But if some peole fck up their hmd with it i guess they should just puta manual in the box and say the DO and DONTs…
I am glad this is turning into a constructive conversation.
The idea behind using smart film was having a luxury option that works automatically. It turns transparent as soon as the proximity sensor on the headset is triggered, and stays opaque otherwise.
It would be nice to eliminate the risk of sun damage entirely, instead of relying on users being careful. Just a few seconds of direct sunlight can cause damage, and that can happen if someone is absent minded due to an outside interruption, just puts the headset on the table, and leaves. Meanwhile the direction of sun changes before he comes back and burns the screens.
It’s also tempting to think it would never happen to you, because you are always careful. But even if that’s the case, would you trust your family members to handle the headset with care every time, or would you rather not have to worry at all?
I am just suggesting to investigate the pros and cons of such a solution, be it built in, or as an optional module.
DP 1.4 would only be enough if Display Stream Compression was used. That is designed to be visually lossless for screens at normal viewing distances, and might be much more noticeable in VR.
I am also thinking long term. 8K X is currently just a very limited edition, targeted for release in May 2018. By then we might now the performance and features of next Gen GPUs. A consumer release months after that could be redesigned to support the new interface.
I guess we have to wait and see how it plays out.
Interesting. A module with the smart film using the “VR frame Adapter” could be an idea for an option!
One problem with films though it can often dull the picture as when on/transparent as its usually has a slight tint. This was mentioned before about phone’s screen protectors with vr goggles.
But for peace of mind for people like yourself, I think with PiMax’s Sdk/hdk be doable if need be.
