Bigscreen Beyond - 5k OLED and tiny

BTW, do we know that the factory set personal IPD cannot be adjusted DIY?

Surely they have a standard mold with rails that are spaced as per the user specifications and then fixed to their position? If that is done with a screw rather than glue, adjusting the IPD DIY style should be absolutely doable.

Or is the issue that the physical settings are somehow baked into the fw per device, hence reporting a fixed IPD value to whatever API?

Darshan talks about it here at 8:10

Oh iā€™m pretty slow on the uptake here (sorry), so the ipd is set at the factory? If that canā€™t be fairly easily be changed by a user then thatā€™s a major negative imo. I just thought it was the facial gasket that was made individually.

Yeah the eye boxes are fixed.

It might be a step too far when you look at how well the Pico 4 and motorised IPD adjustment works.

If Byte Dance only made a Pico4 Pro with 3k OLEDs.

One tend to imagine tooling and stocking of the multiple variants must contribute non-negligibly to the price, and that having a single frame with a range of slots for optical modules to plug into, shouldnā€™t have had significant effect on weight, bulk, or rigidity, but hey ā€“ itā€™s easy to armchair-engineerā€¦ :7

Given BigScreen share all the CAD files, apparently, I guess a more tinker-minded user could adapt a BSB for a new user, by 3D-printing the appropriate substitutes for its original framesā€¦

Given the rough milling-like surface structure on face masks seen in videos, Iā€™ve been wondering whether the silcone facemasks are maybe cast in 3D-printed moulds, which strikes me as the simplest one-shot manufacturing solution ā€“ face side down, and the frame with the magnets slotting in up at the brim, prior to pouringā€¦
I wonder, then, whether the user gets the .stl for their personal face mask, along with it. :7

PSVR2 possibly as the iVRy DeV has made significant progress and has reported he has tracking working.

BSB is still also very expansive for jist being a hmd. Index sales has been reported to be on the decline but still will be appealing for new wired pc users.

Crystal? well once they have the inside out controllers working well will have a lower price for a full package.

I do believe even with BSBā€™s negatives like low brightness and reduced clarity towards edge of FoV. It will be a decent upgrade path fir those with low ti average ipd(as high ipd suffers fiv loss horizontally). The low weight & form factor are a plus.

If BSB can run on Amd 6800U and higher at a reasonably decent level as Green on discord has managed with 5kS it will be quite appealing as it opens up a neat powerful AiOish idea. Green was testing with the gpdwin gaming laptop.

New negative for BSB at 90hz seems only 1920Ɨ1920 per eye. 75hz full res.

Itā€™s not a ā€šnew negativeā€˜.

Itā€™s the exact same information @tykey6 shared a few posts up.

And as I explained, that is DSC. If that is a negative then the Crystal is equally affected, as are all other HMDs that use DSC.

Lol yeah thatā€™s how the crystal works too

Haha NVidia pulled the plug on Virtual Link too early. Hopefully it makes a come back on the 50 series. Too late for this gen though.

I consider the BSB to be aiming at as small & light as possible, and fixing the IPD in factory was part of this concept. I accept it. Tailor-made clothes/shoes are not as easy to fit to somebody else, but they give you a better experience than standard sized clothes/shoes.

The resale issue of the BSB is true, but then again, how many of the headsets I own did I resell? Some for sure, but others are still here, in my small VR ā€žmuseumā€œā€¦ and the BSB would be the first of a truly different form factor, would look awesome next to the retired 8KX, just to bring home how wildly different the approaches to VR where at the time of the 2nd/3rd generation.

Yeah I think the resale argument is a red herring because for every BSB sold with an IPD of say 64 will equal the same number of 64IPD second hand buyers. In other words the average IPD sale will be equal between new and second hand. The gasket should be brand new though.

No, this is a different issue than dsc. Both 75hz and 90hz use dsc, which isnā€™t the problem. The problem is that 90hz also uses a lower resolution which is then upscaled to native. That means that 90hz mode will never be as sharp as the 75hz mode. Which in itself wouldnā€™t be a big issue except for the fact that bigscreen themselves either didnā€™t know or purposely misled people to believe it was just lossless dsc when in fact itā€™s more than that.

Are you 100% positive on this and in particular the statement that the BSB used DSC even @75hz? I would find this extremely surprising because the BSBā€˜s resolution should just about fit into DP1.4 spec @75hz.

If the overall statement, however, turns out to be true and I see mounting evidence on Reddit that your correction re DSC vs. additional upscaling is correct, then not only do I absolutely stand corrected but also would have to seriously re-consider my preorder.

Both Tested and Sadleyitsbradley both confirmed that itā€™s only using 1920x1920 per eye when at 90hz. Itā€™s even shown in the specs of the seeya panel theyā€™re using that both use DSC and 90hz can only be achieved with the 1920x1920 res. (See this reddit thread https://www.reddit.com/r/virtualreality/comments/153floa/finally_confirmed_bigscreen_beyond_not_native/)

Lower res than full(.5k less) at 90hz not a negative?

This post explains it is a panel limitation and that is shared with the defunct Apara 5k hmd as there using the same panels.

It is a negative but the same issue had been shared by @tykey6 just a few posts up; that and the fact that I incorrectly understood the ā€šupscalingā€˜ taking place to be just DSC led to my reply.

This new info just made me cancel my pre-order. I absolutely will not deal with a below 2K per eye render resolution, no matter the form factor. If I want my eyes to bleed I might as well get a Quest Pro that at least has functional lenses.

Itā€˜s a damn shame how this went and other than the AVP, I honestly donā€™t see myself buying another VR HMD in the foreseeable future. Itā€™s all jank.

Well from what I hear the BSB Ceo Foster that idea that the upscaling was just DSC. So he had help seed the confusion by misrepresenting info.

Glad to hear you cancelled. After learning more tonight is even less appealing. The Micro Oleds are also pentile. So picture quality will not of course be as good as full rgb stripe.

BSB currently has no real return policy and has been reported on there Discord gets a bit aggressive when asked about one.

After these negatives am less interested in BSB. Micro oled and pancake lenses need more time to mature. Apparently some of those whom did receive Arpara 5k have had to do fan mods as there are issues after the micro oleds start to get hot. One fellow on the pimax discord said with Arpara his developed burnin after jist 300 hours of use.

BSB is apparently using either the same micro oleds or a version that is a step up in terms of a bit more brightness.

Yep, also just cancelled my preorder.
Also last week I ordered a Crystal from Unboundxr in Netherlands as they have a very good return policy .
Just arrived with Dmas, hub & fibre optic cable.
The news regarding wider lenses coming got me interested in Pimax again. (I know)
I tried Quest pro and just didnā€™t like it that much.
Keeping vr3 as I have 2 completely separate rigs in different locations.
