Definitely right. My eyes are ageing fast enough as it is.
I've put the filters back and set the brightness to 1 level above normal and although the colours are not as crisp I'm happy with the display.
The blurriness with head movement has been reduced a bit as well which is a bonus.
I am convinced that by correctly blanking the video at the frame rate during head movement, will go a long way to reducing this affect.
Many years ago, I worked on the design of blanking circuits for phosphor based (CRT) colour television tubes and even more than LCD's, they suffered from image persistence and this (among other things) was controlled by correctly blanking the video in between image frames.
This is already happening in Pimax with displayed video images and that's why if you keep you head still, there is no blurring. of the image as things move. But I believe that there is some issue in the firmware/software relating to the speed (lag) of sensing the head movement and adjusting centre of the displayed image "viewport".
If this is not handled quickly enough and not correctly synchronised with the frame blanking period, then a double image or shadow will most likely result.
This is what I believe is happening and why there is a difference in the image quality and shadowing between Piplay versions 1.1.92 and 1.2.xx.
Oh yes and damn, I've got a bit of dust inside the headset that's going to drive me crazy, but I'm going to live with it for now. I'll have to improve my dist free work area if I'm going keep fiddling with the guts of my Pimax.
