Has a pair of 2,560 × 1,440 OLED displays running at 70Hz, a 150-170º FOV and doesn’t use fresnel lenses. But is huge and heavy.
Road To VR also quoted the “5K” as they had done with the Pimax “8K”.
…the overall image clarity from the VRHero was notably better than what I’ve seen from the Pimax “8K,” despite the “8K” using higher resolution displays
That’s for the smaller FOV of 150-170º and the new lenses.
“While they’re not exactly positioned as competitors (as Pimax is aiming for consumers, and VRgineers for enterprise), the overall image clarity from the VRHero was notably better than what I’ve seen from the Pimax “8K,” despite the “8K” using higher resolution displays (3,840 × 2,160 per display, vs. 2,560 × 1,440), which is a bit counterintuitive. I asked VRgineers why they thought this might be the case; they say that image clarity is their number one priority, and so they selected the best components to maximize visual quality across the entire pixel to photon pipeline.”
the view in the headset is ‘display limited’ rather than ‘lens limited’, meaning the lenses had a somewhat wider field of view than the displays; by not filling the entire field of view of the lenses
Yes, that’s what I meant that they’re using 100% of the panel’s pixels. Downside is indeed the sharper edges. I myself could live with that (I have sharp edges too after my Pimax 4k mod where I moved the lenses a bit outside to correct the IPD)
The headset with its counterbalanced weight clocks in at 1.08kg, more than twice the weight of the Rift or Vive, or the equivalent of about 30 pairs of sunglasses—not to mention it’s much larger in volume, which further increases its rotational inertia (the effort needed to start and stop rotation of the headset)
The big rotational inertia is the worst issue. The developers must reduce the volume and weight. It’s not even usable.
I assume it will be sharper because it uses high quality optics which make all the difference, also it’s native input isn’t it? so no scaling that would soften the image.
This is why pro photographers spend thousands on a single lens. The work that goes into pro grade lenses is much more involving (using humans) than cheaper lenses which are produced using automation.
Fresnel lenses allow for thinner optics and use ridges (instead of a convex shape) to redirect the light back to your eyeball. That’s why they are used for something attached to your head as they are lighter too but you lose light (from light scattering off the ridges). If you use more ridges to redirect more light towards your eyeball then you get a brighter image but lose sharpness so you have to find the sweet spot. I imagine Pimax have had a massive challenge getting these right.
The VRHero, I assume, uses standard optical lenses and would be the reason it weighs so much but the benefit is clarity, just like from a decent SLR lens.
They are sharper not because of the optic, but due to FOV and no upscale. Overall, if you can see screen door effect of the screens, it means that you will not benefit from better optic, because it is not the optic, that limits clarity in that case. It is screens and image resolution (if upscaled)! Better optic would allow you to see SDE better, but would not add any details to the image.
You can’t see more, than screens are showing. There is no magic here. And if you can see pixels or even sub-pixels - this is it. But you can believe in Magic, why not
