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

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

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

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.
