Dear Pimax Family,
Long story short, I have spoken to the int' director at Pimax, she proposed to use latest drivers to solve the ghosting issue.
My Pimax 4K Serial: 10071170802599
So here is the report:
After patiently waiting long time to see a great improvement to the ghosting issues following the promise from Pimax to improve that with drivers/firmwares, I have tried the latest piplay setup/drivers. Well, If I don't move my head, no ghosting. But if I move my head its like the ghosting "Follow up" the image. So the ghosting is pretty strong still, even in the latest drivers setup.
And it is very well noticeable, lets say you move your head to the left side, the transparent grey ghosting is like lagging behind the image it self and follows it.
Anyone found a solution to this? or its a factual issue which cannot be solved?
Little history teller: My first Pimax 4K was defected out of the box (hairs and blue lines all over the screen), Pimax support was very awesome to handle this situation, once confirmed it is indeed hardware defect, the first one shipped back for RMA and Pimax sent back an replacement into a new one, the new one that was delivered was "an old batch" with a tiny little hair on one of the eyes, I got a special permission to take the device into an optical qualified LAB to clean this hair, which was cleaned with a success, Pimax credited me for the cleaning costs. However, I been told that ghosting issues should be barely visible and shall be improved even further with updates to come. In my case, ghosting at this point with the latest drivers is still very very well visible in 360 mode where I need to move my head. So I hope Pimax engineers got any software/firmware level optimization for it, otherwise, its pretty discomfy experience.
And to add additional confirmation:
This lagging/dragging grey ghosting appears also on Piplay official showtime app. As much as I want to ignore it, Its far too disturbing the eyes tbh. I been waiting penitently for a long time as to promise from Pimax to optimize the ghosting issues with drivers/firmware updates, yet so far, it didn't improve, hence this thread opened.
