Hello guys ! Just got my new Pimax 4K , I want to say straight this is not my first VR headset, as I have had 3 different brands and models in the past, a Deepon, an Oculus, and still own a PS VR, but this is my first with a LCD panel.
The problem I have seems to involve the IPD calibration; after finding the correct IPD value (even measured mine with a precision centimeter) I was not been able to make it clear in the center of the view, the screen all around is perfectly focused but there is a circular spot in the center that always stays slightly unfocused, even all the area around it, in all four directions is perfectly clear; any ideas why this happens ?
Lastly.....ghosting effect.....wow.....this is my first non OLED headset but I really never imagined it could be so noticeable when moving the headset around, it is really quite evident, hope this will be reduced with future software upgrades and that Pimax works hard not to make the 8K the same ugly ghosting amount 
Thanks in advance for any advice and suggestions.
