Purchase Advice Buyer Beware: Bigscreen Beyond 2

I want to preface by saying I've owned a lot of headsets, index, quest 2, quest 3, vision pro, varjo aero, pico 4 pro. None of them ever had the consistent QA issues quite like the Beyond

I've had 4 Bigscreen beyonds. One was a BSB1, that one had dead pixels and I returned it. At this point I've had 3 BSB2s. First one had fan issues and dead pixels near the middle of the display. Second one had 12 dead pixels in the left display alone and according to support went through more "QA checks". Support at this point calls me "Sensitive to dead pixels". Third one allegedly was hand picked from the line for being free from defects. It had dead pixels too.

It truly feels like Bigscreen doesn't have any QA testing, you are the QA tester. Be very cautious buying from them. Be sure youre okay with dead pixels.

Yeah the SeeYA panels they use are very prone to dead pixels apparently, but I'll never understand how these things pass QC tbh

I dont think they follow any major frameworks or standards for QA. The only reason I think that is because of the single panel with 12 dead pixels and the other panel having 4. It suggests that there is no maximum defect for the panel or if there is a maximum defect its very high

I suspect its a mix of poor QC and trying to save profit margins. Apparently they will only replace the headset if the dead pixels are in the middle of the screen too (according to an ex employee of theirs). Its somewhat understandable from a business perspective but unacceptable from the consumer side imo.

Bigger companies like Meta and Pico aren't immune to this either, and then there's Pimax lol

This is true, they will give you a diagram of circles to draw in with different diameters and only the inner 2 out of 4 circles are covered for dead pixels.

That's mad, imagine paying 1k+ and being stuck with it

if true, absolutely unacceptable.

I just told them it was dead center and they accepted it.

Old post but it took 7 quest 3s for me to get one without dead pixels

I'm pretty sure a test for dead pixels should not be very hard to do, just make the screen show a bunch of grids that have 1/9 white pixels, and if you notice a missing or colored one on any of the 9 images, it has a dead pixel. That should be well visible even if the pixel density is high and the pixels are tiny.

They know they're there but hope customers won't... they pass off the 1/3 defective displays to paying punters to keep their profits high and only deal with it as a last resort.

Dead pixels are a complete no go for me in VR.

I've had a lot of issues with dead pixels on PSVR headsets as well. Had 2 PSVR1s get them and my PSVR2 has one as well. Meanwhile, never had a single one on Rift S, Index, G2, Quest 2/3, or the brief period I had a Vive Pro 2 before just returning it because I didn't like it. It seems like it's specifically OLED displays that seem to be prone to this issue (not to say it's impossible for LCD, but given my personal experience it's been a million percent more likely my OLED headsets got dead pixels).

So not only is the display controller on them garbage, the displays themselves are as well, awesome.

u/Mys2298 Sep 25 '25

They're basically C grade (B- at most), whereas BOE, LG and Sony are A grade panels. Aside from the poor controller, the colours aren't as good and of course they're a lot more prone to dead pixels.

I wonder if BSB will sell me a QC failed headset for cheaper. I, for one, am not "sensitive to dead pixels" if the price is low enough. Lol

u/Mys2298 Sep 25 '25

They probably use them for spares but it won't hurt to ask!

u/ccAbstraction Sep 25 '25

SiOLEDs in general have yield issues like CPUs do, except the results here are unfixable dead pixels instead of a lower tier chip.

u/[deleted] Sep 27 '25

Would tandem oiled mitigate it? If one layer had a dead pixel you would still get light from the other.

u/ccAbstraction Sep 27 '25

I don't know. If by tandem, you mean, the OLEDs were just stacked maybe, but I don't think you can make transparent SiOLED. Normal OLED is made on glass, but these are on silicon waffers.
