Looking for Small Hi Res LCD used in Oculus && || VR et al

[Mechatrommer]

Isn't the Vive really expensive?  When I was buying the Oculus which was £399 then, Vive was like £750!

i'm looking at the used market. i can grab one CV1 for about $300+ now, there are also few vive thats currently on $200+, but bidding is on the go, i'll wait how much the price will end. for the purpose for only SIMming and gaming, i'm not sure if i'm willing to spend $400+ for any of them, add $100 more for shipping cost to here. we have them sale locally, even if shipping cost will be like $10, but they are $600+ price range (new, no used unit on sale here)

Also, Windows 10 versus Windows 7 is like night and day.  Literally Windows 10 actually works and is at least 4 times faster than windows 7.

i experienced the other way. we have 2 machine on Win10 here, the one is PC for printing shop, over time, and now it boots very slowly. the other is SWMBO new laptop, got it updated last year, and now its like turtle slow, SWMBO always complaining, i dont want to touch it she asked for it (latest boombastic OS) i dont care much about privacy, there is very little to hide here. further, the most powerful PC currently at home is used HP Z800 workstation, 12 x 3.46GHz Xeon 96GB RAM and Radeon RX580 8GB, its natively (originally) designed for Win7 and came with a S/N, i think its the only machine that can pass PC requirement and i dont feel like to upgrade it to Win10, i can, but what its worth for? not much i think, for me. and i'm one of the rare believer that older OS is much stable than the latest one (putting aside security matter)

Interesting your experience with Windows 10.

I have it on the main gaming PC, Ryzen2700X,16Gb,1070Ti and Windows 10 boots in about 1/3rd the time it takes the motherboard to POST.  Desktop in about 40 seconds with 30 of those spend waiting on the Bios to post the Asus logo.  The monitors switching into full res usually takes longer than it does for the login screen to appear and I can get my pin code in before it does usually.

I also have two S/H Dell small form factor PCs as media centres and I let them "fall asleep", both wake with a single press from the wireless keyboard and by the time you turn the TV on they are at the login screen.  These are like 2nd gen i5's 2.9 with 8Gb RAM.

The one thing however I think Windows 10 loves is an SSD.  I know Windows 7 runs faster on an SSD but Windows 10 seems to thrive on it.

I don't see many reviews suggesting the Vive performs better.  The specs are nearly identical, so I'm curious what you mean.

If you compare old vive model which is now much cheaper and new oculus specs look similar. Still even on old vive tracking is much better than on new oculus. Also it has wider viewing angle. But you can also buy vive pro.

spending more time researching on "immersive" VR more than i expected. its off topic from whats originally intended but i hope its allowed. i figured out we can put larger screens together and the eyes can still focus, its all about the lens in the middle bending the lights, even experimented with and dismantled my china cardboard VR. that was my concern if the screens are too large, eyes have to make "inverted" cross which i'm incapable of doing, but it seems now possible, so screen size is next to irrelevant. ordered another BoboVR Z4 SP goggle $15 should not hurt much, just for fun and experimentation.

so back to VR and Flight SIM, what about Pimax? i saw positive reviews from MRTV "The Mr Ang" and Linus Tech et al. and is fully compatible to Vive system. the 8K is too much expensive and not available in fleabay market. the 5K is 200deg (similar to 8K) eye view angle is a huge difference from normally offered by Oculus and Vive 110deg. probably just using similar size and density to Samsung screen (but LCPC? type) not many in fleabay in fact only 2 currently $400-500 used. and there is just few days announced new budget range $450 Pimax Artisan... 170deg diag and 140deg horz is still huge compared to 110deg... https://store.pimaxvr.com but the bad news is i heard they still struggling to fullfill their backers after the years on 8K model.

btw. just trying few lcd around me. SJCAM (GoPro knock off) vs SAMSUNG GALAXY A7 lcd. SJCAM has more visible pixelation behind the magnifying lens, but when looking under microscope, they actually have the same pitch, except SAMSUNG one uses bayer pattern (diagonal). so bayer pattern actually works to make lcd looks better.

It's AMOLED, no LCD. And it's pentile, there are no definite pixels as such.

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...  maybe i will keep looking 2.5K res 5K+ 200deg FOV in fleabay used market as an option.
