I just got my Pimax 4K today and I cant seem to get around this problem.
No matter what IPD setting I try, or how I position the headset up and down, I cannot get the green cross in the calibration screen to be sharp, BUT the wording all around it is crystal clear.
Same issue occurs in games, the center is blurry/out of focus but all around the center is sharp and clear
I've tried it with and without my contacts in, same effect either way
I tried to just get used to it but after only 10 or so minutes of play it really starts to bother me.
Am I missing something or doing something wrong?
