Add me to the no filter list as well. (There went my warranty but totally worth it)
Using the lower than normal brightness used to be undesirable but not anymore.
Thanks for the procedure steps, sjef.
What's with the blurring when turning head briskly and can it be reduced?
It appears the Blue Light Filters were in place to minimize/hide this blurring effect as well.
A quick mention:
While cleaning the lenses, on my side, it was possible to have the Pimax completely open, minus the front cover that houses the LCD.
This allowed easy access to the lenses/glass.
My Pimax was in this state for hrs w/ SteamVR running.
As sjef mentions, any little speck on the screen is very annoying
