Looking for Small Hi Res LCD used in Oculus && || VR et al
paulca:
I'm not sure a wider FOV would be favourable over the higher res. I never find myself wishing for a wider FOV but I do fine myself wishing for a better resolution.
I can see how if it got to 170* FOV you might start to get peripheral vision motion effects to enhance the feeling of speed.
Having a 1080x1200 screen right in front of your eye sounds great, but it is only a few cm from your eye, if you sit that close to normal 1080p monitor it looks lower res.
But.. it's more the expanded field of view that hurts the res. I think if you zoom and focally warp your normal monitor view to include all that the VR headset does you will notice a drop in detail. For me this manifests in the multifunction cockpit displays not being easy to read and on carrier ops you can't make out the "meat ball" at 3/4 mile without using the VR zoom function.
8K VR sounds awesome, but I believe the issue is, nothing practical can run it. I'm not sure if it was PiMax or the other one that came out was something like $8000 dollars can came with dedicatedly tuned video cards... yes cards.
The Oculus involves two 1200x1080 screens and a mirror on your monitor which you can sometimes reduce in res, sometimes not. It struggles to get 45fps with high details, becomes seriously stuttery with the sliders maxed, where it wouldn't on a single 1440p monitor. This is why most of the "off the shelf" VR games in the occulus store etc. are absolute rubbish, they are so low res, low detail to keep mediocre systems running at 90fps.
I haven't watched the LTT video on the 8K VR, I might watch it tonight, but I'm going to guess they are throwing some serious hardware at it, like dual 1080Ti SLIs or similar and probably still complaining about frame rates.

attached is spec comparison that i copied from iirc reddit forum... 8KX is 3840 x 2160, ie basically a full 4K res per eye... native 2 x 4K rendering, from review you will need number one gfx card on the market ie RTX2080 iirc. $1200+ is still cheap (but not that cheap for me) compared to developer's version of StarVR or XTAL VR, not available for muggle like us, even if it is, they are beyond affordability anyway. https://virtualrealitytimes.com/2017/03/06/chart-fov-field-of-view-vr-headsets/ the 8K+ is upscaled rendering by built-in MCU. 5K is 2560 x 1440p per eye (twice the rift's or vive's), ie a normal screen size of my monitor here warped into 200 degree field. with latest Artisan, they reduced to 1770 x 1440 res and reduced 170 deg field, closer to what rift/vive offer (but still much greater) at much cheaper price. from the scaling they are trying to do, it seems rational, ie reducing screen resolution and hence reducing field of view to maintain clarity experience as their top 8K version. MRTV Sebastian Ang got in depth into this. he even showed 8K and 5K behind the lens side by side, we both agreed 5K is better rendering and sharpness. its a surprise since 5K is much smaller res screen albeit same FOV. it must have something with drawing algorithm or the lens. and he did try Artisan prototype in CES2020 and concluded its just as good as 5K with better God ray effect. i was just one click from ordering the Artisan from their website, but their less trustworthiness to their backers made me wait for a while, maybe until some youtubers got it into their hand and make a review... new stuff always tempting to click without much thinking... :phew: maybe i will keep looking 2.5K res 5K+ 200deg FOV in fleabay used market as an option.
