Black is not black, it is gray

Hi, I recently acquired a cv1, and from the first moment I constantly see grayish granules on most of the screen, especially on the left side, and when it is black, does anyone know how to solve this situation? I have tried everything, several adapters, both displayport (active and passive) and dvi, and they do not solve anything, I changed the graphics card drivers to previous versions and with clean installations, and nothing, until I reinstalled the OS several times , I even deactivated spud and the grainy disappears, but the screen happens to have a generalized grayish color very annoying, not to mention that the levels of black happen to be "256 colors", I do not know what to do ... someone Could you help me? My O.S is w10 and my graphics card is a gtx970. A greeting and many thanks to all.

    Please delete/erase anything you did with SPUD registry entries.
    Deinstall Oculus.
    Reinstall Oculus.
    Supply screenshots please. Right now you're talking about two things, the "256 colors" and then that blacks are not black.
    Also: do NOT use any adapters with the Rift. If you use an adapter, ONLY for the monitor. Also, both, Rift and monitor must be on the GTX970. Since it only has one HDMI (likely), you need an adapter/cable for the monitor.

    Also..for reinstalling your GTX970 drivers, use DDU (display driver uninstaller) and get rid of everything first.

    Its probably the gtx 970 tbh, i have heard of horro stroies with it. I have seen people have better results using the display port on the gpu by using an adapter cable.

    That's not completely abnormal. The black levels won't be quite as good as a monitor. In addition, each screen has some natural irregularity, so it's possible (for example) the contrast to be slightly different from panel to panel. If it seems really extreme or bothersome, please submit a support ticket. Thanks.

    Thanks for your answers, and installed everything as you say, step by step, and I get the same results, right now I can not take pictures to the screen, but this afternoon I will try, I have done an absolutely clean installation, again and It does not change anything, I still see the gray spots, like dust. I do not expect it to look like an OLED monitor, but I do not think it looks worse than a lcd from the beginning of the century, I understand it is not absolutely black, but seeing clearly gray displays is not normal.

    I kinda have similar "issues" if I may add it in this topic.

    On left screen (sometimes with totally black screen when loading) I can see plenty of gray dots. Right screen is ok. Dots are not visible on all black screens or on color at all.
    Colors look a bit washed out and some games like dead and buried look like 256bit colors, especially in main menu with fog and black background.
    And ofcourse optics create a ton of shining and so on. It feels like Riddick sometimes but it's not that bad

    Your rift is a new bundle???Seems to be a widespread problem in the new pack of rifts, many people are complaining about this problem for what I am reading on reddit...

    Thanks for your recommendation, but what I see on the screen is far from being normal, I have opened a case in oculus support from day 17 and no one answers, I understand that they are very busy, but wait a week to Start giving me an answer seems like a long time, anyway thank you for your help !!

    Yes it's new bundle. I just created topic about problems with my rift here https://forums.oculus.com/community/discussion/56732/two-problems-one-with-left-lens-and-other-with-screens-please-advise#latest

    I am not sure if I will open a claim yet. Waiting to see what support will replay to me in my topic. Both problems I;ve described are annoyances for sure.

    The one You are describing is also my problem. it's this pattern of grey dots in some parts of the screen. Clearly visible on black background but also on grey. It's like a layer of dots visible on some colors.

    A slight "mura" (film grain, static dust/speckes overlay that doesn't move) over certain blacks is NORMAL. This however shouldn't be visible 99% of time, only if something is entirely black. If you have strong mura visible elsewhere, a defect COULD be possible. (Hard to say without screen shots).

    "256 colour" effect (I know what you're talking about) seems like a defect to me, should not happen in 99,9% of games, apps. I have only seen this once but it was likely because of the game/demo in question. If you have this, likely some display effect unless it has to do with adapters or some weird driver issue.

    "blacks not entirely black", we have this problem quite often:

    Although the poor blacks because of an incorrect dynamic range in the Nvidia drivers should not be related to the 256 colour effect or the "film grain". But you should still give it a shot. (Read the above two links how to check whether your Nvidia driver dynamic range is set to "full" and how you can set it correctly)

    Thanks for your answer, as you say, a slight mura effect is understandable and appears randomly, what is not normal is that any image minimally dark, I do not say black, you see that "gray dust" ALWAYS, also yesterday I was noticing that in the left eye over the top you can see the gray dust "shaking" like the old tvs and there was no signal. In addition casually yesterday I put a game of space terror and I entered the laughter, on the monitor was a corridor FULLY dark with a door in the background, well, in the oculus, apart from the famous dust ... I saw all the walls Of corridor in green and gray with gradients of 256 colors, absolutely sultry ... I love the excuse that we are not allowed to touch cv1 parameters because they want users to enjoy the author's experience ... as we will enjoy the experience if each cv1 looks radically different from another. Yesterday I tried to reinstall everything, o.s. All drivers, runtimes, and nothing ... everything was still the same, besides probe my girlfriend's cv1 on my pc and it looks perfectly, so I've definitely ruled out that it's my pc.

    Here you have an image of the corridor for example, another with the interpupilar adjustment and another with load screen, and I assure you, that these photos are not very well made and attenuate much what actually looks.

    Mine looks like Your last image Name2017.
    Except that I have correct colors. The grey pattern of dots is visibla on about half of screen on left and right eye.

    Because I can assure you completely that all the images that I expose are very very attenuated, what you see with the cv1 post is much more exaggerated, my smartphone does not photograph too well.

    Definitely not normal.

    Do you have any friends with VR capable machines?
    That'd be the easiest way of verifying whether it's your GPU, rift, or some aspect of your configuration that's at fault.

    I know perfectly that is the hmd because my girlfriend has another cv1, we have installed and his works perfectly so I do not know what solution I will give the official support.

    Image 3 looks EXACTLY like mine (the green "nebula" thing). I returned the unit right away. Don't waste any more time, RMA that stuff. Something is up with a bunch of these first Rifts because there are too many people reporting this. Right lens, right?
    And you have a whole number of different problems, the "green stuff" only one of them.

    If I already said, this is a festival of failures, and it is only left on each screen comes out one melon and in the other a watermelon and we could close by full capacity.

    Here is a clear example of the combination of everything at once, and the most flippant  is that the room that is "lit" really should be completely dark ...

    So, the screens can have some level of artifacts, but those pictures are far beyond what is normal. Please contact us and inquire about a replacement. Thanks.
