Does anyone have a flawless Oculus Rift?

[Lemny]

Now I got my fourth Rift.

My first one had black level problems on one eye. The other eye was ok. All three replacements had the problem on both eyes.

This guy had the same problems with one eye: https://forums.oculus.com/community/discussion/41989/calibration-veil-compare-method-on-cv1

The test picture should look like this (captured from my LG TV) http://imgur.com/EYTkw8W

In my all my Rifts and in the one eye of the first one it's shown as this: (in Oculus photo viewer) http://imgur.com/9x7mK7O

I looks like the black is black and the first really dark grey has a jump to 16/16/16 or similar. Looks like a limited RGB range pic used on a full RGB display. But since it's possible to only have this error on one eye, it couldn't be a driver issue.

In ELITE it results in this:

Could you guys and girls out there check your Rifts? You can get the test pic from the linked website and/or check the border of your galaxy map.

The Oculus support is very nice. They have a name for that issue: "Black level error"

I also checked two other Rifts of my friends and both of them had that issue. Since they only play bright games like DCS an Project Cars, they didn't notice it.

I've played Elite Dangerous more than any other title on my Rift since I received it in June. I have experienced some of the things you mentioned, like the static haze which is slightly visible in very dark scenes, and some dithering in shadows. To be honest, I just kind of accepted it and didn't give it a second thought. I never expected the color and contrast to look as good as my 1440p IPS monitor.

Let's be real. At the end of the day, you are flying a spaceship around in virtual reality. Forget about black levels and just try to enjoy your game.  😉

Got my replacement CV1. Much better (new photos in test image thread😞
1 & 2 (left/right eye)

Same here, but left:2 and right:1 or maybe 3 & 2

But I thought higher numbers (5) were better?!?

Same here! I notices a haze in dark areas but didn't really care before I read this discussion.
Most of the time I hardly notice it and when I do, I still don't really care to be honest. Have to try ED as soon as I find the time for it.

Yep mine has the cloth, mesh type haze as well.

@Fiege: Depends. Not so much good or bad. Just a range to try to find where Oculus tries to 'lock' their one-calibration-fits-all. Independent of how one likes 1 vs 5 in photos. After the last result in my other thread, and other references, my best guess is that 1-2 is what Oculus is aiming for.

I think Oculus's problem is that they really do not have good enough handle on the variance on OLED screens they are getting into the CV1. Compared to DK2 they also have the complexity of two screens in each CV1 that can differ. Which was a major part of my gripe with my first CV1, as this older capture of veil effect on my first CV1 shows:

My personal view is that I am ok'ish with what I got now. Would still like Oculus to be more open about the calibration issues. And would very much like possible user options to adjust/tune screens individually.

One consequence looks to be that some developers are looking for workarounds. Elite Dangerous released a beta update that apparently does dithering to reduce banding (quote: "Enabled dithering for VR to reduce banding"). And probably also bridge the large drop to absolute black (RGB #000000). If it continues like this we might get a situation where Oculus releases a new fix to make drop to black better calibrated. Ending up 'breaking' the possible existing ad-hoc solutions.

For reference. I do not think the big jump to black is ideal. As it looks now if you give CV1 screens RGB values #000000, #010101, and so on. A rough estimate is that the pixel brightness jumps relatively 3 times as much from #00 to #01, than from #01 to #02 and so on. And because hex #00 and #01 do not have any value in-between, one needs to dither to avoid dark banding. Or maybe make #01 the lowest value to use, but missing out on absolute black.

Nope, mine has had several problems. Mostly revolving around the HDMI.

Do you have HDMI disconnects?
I figured out, that this can be caused by a power loss on the USB bus.
I got these discos while plugging in my X55 Hotas. After using the X55 on a powered USB hub, ich got no disconnects of the Rift.

The gamma problem still exists in my current (fifth) Rift, but a bit less than in my other Rifts. I think Oculus is not capable to do it better. But I am so happy with my touch controllers, that I decided to life with this until the next generation of VR headsets. Maybe my next one is a Vive if they make better controllers. They are the strongest argument for the Rift for now.

5 & 5 for mine.

@TickTock: Maybe Oculus is trying to match L&R calibration, than calibration itself. Do you think yours 5 & 5 have a good match TickTick ? My biggest problem was more the mismatch of L&R, compared to if it's 1 or 5 (except the coarse veil on L).

I could see no difference in the pattern when I closed one eye versus the other.  Does seem like it falls off to black rather quickly.  I've never really had any issues with the video quality but I checked after reading this because I was wondering if I am just easy to please.  🙂  I guess I got a good one.

I always thought my rift was faulty H)but now I see its because some games use dithering (God awful effect)
I first noticed it when I fired up the final version of valkyrie and compared to the dk2 and the alpha it was God awful!
That said the god rays in the hanger would have been so bad otherwise it would have been in bearable. Fucking fresnel lenses 😕
