Terranigma I've been following PIMAX 8K/5K from the very beginning, I almost backed that campaign instead of Cinera, as they were both active at the same time. The 'problem' with the PIMAX headsets is that they are very much optimised for VR.
My understanding is that the headset isn't designed to simply behave as an external screen and display a 2D picture if you plug it into a computer (any movie experience would need to be presented within a VR environment, using specialised software/drivers), and the hardware demands on using such a headset are very high (cutting-edge or next-generation GPUs and a premium CPU with a LOT of RAM).
The fact that the connector is a DisplayPort 1.4 and there is no HDMI connector shows that this is not intended as a general home entertainment device for use with other consumer audio-visual equipment.
Also, although the native resolution of the screens is 4K each, the input video resolution is 1440p on the standard model, which is upscaled to 4K - which is the same resolution as the 5K native resolution. The 8K PLUS version (which was a limited edition and no longer available for purchase) can input the full 4K per screen, but it would need an ABSOLUTE MONSTER computer system to run it, and this resolution is not widely supported by software companies at the moment.
It is still very interesting though, and any product out there that can push the boundaries of this kind of headset tech and drive forward innovation and competition in this market is welcomed by me. :-)
I particularly like the idea of the 200 degrees of FOV. I hear that in VR experiences, there are still narrow black lines perceivable at the top and bottom of your view, but the edge of the sides lies beyond your peripheral view.
When it comes to optics, I ideally would like the choice of watching a movie in a window where I can clearly see all the edges by moving my eyes around the screen (not obscured by the edge of the lens, as is the case of Cinera), or as a more immersive alternative, I would like an 'Infinity Screen', where the edges of the screen are beyond my peripheral view and perceivable to me - the effect would feel more like my natural sight and less like the 'tunnel vision' experience of watching a movie with diving goggles on.
Whether or not there would be technical issues with displaying standard movie aspect ratios (even IMAX) in this way with regard to distortion from the lens, etc, is beyond my technical knowledge - but it would be very cool!!! :-D
