    Edit in 1,
    Made some updates to this original post in the end, and amended it with a new post, little bit on considerations using hdmi out for fpv googles.

    Edit in 2,
    Changed subject to proper reflect the sad "state of affairs". (for me)
    Posted Ziess replay to my inquiry as new post in the end, with the second try text on my question which is a little bit different than the first.

    Edit in 3,
    Got it to work with some additional hardware, post about that later in thread, update of subject.

    ---------------------------------------


    Bit "depressed",
    Well one should never assume anything, but I did and the result right now is both expensive and a bit disappointing :)
    I have tried to find some viable information on those goggles (Cinemizer) in conjunction with Nexus 7 with Slimport but did come up empty so I will make this post here so perhaps the next smarter than me guy can avoid my mistake.

    First,
    Make a post to support to make sure it actually works or otherwise find some good solid info that the hardware combination that you will buy will actually work.

    I have made a post to there support (Ziess) and I will see what comes out of it, and if lucky you will have a review if I do get things to work out later.
    And yes it's a expensive piece of hardware but it will be on the head and not in the air and hopefully last a while ;) (if it will work)

    My question to there support, with a bit of sugar to hopefully make them in a good mode ;)
    (will update on the matter when I get info.)

    =======================

    Edit in,
    Have not heard anything yet and to rule some simple stuff out I got my self a new 1.4 short cable (had a old laying around testing in middle of the night) with mini to normal hdmi to cut out converter cable.

    And I have been reading up on the subject and I believe a probable reason is that Nexus/google tablets use just the slimport instead of the mhl standard.
    The matter of the fact is that slimport vs mhl is like the old "good" days fighting of standards, like hd dvd vs blueray, betamax vs vhs and so on.

    Mhl is used of so many brands but slimport is hardly used and is a google baby, an interesting article in the link below on that subject,
    http://www.tested.com/tech/android/4572 ... -slimport/

    So now I started to look for another tablet that have mhl and maybe also are 1920x1080 in native so you do not have to put on screen resolution soft on the tablet to change to 16:9 from 16:10 which all have the need for root. (and yes, device now rooted trying out that venue ;))
    Needed to prevent black side bars on scaled Nexus 1920x1200 on display device at 1920x1080.

    I really like my Nexus 7, speedy, just 290g heavy and perfect maps due to google but in the case I do not get it working I probably be changing to one that do work.

    Re: Cinemizer on Nexus 7 v2 via slimport - Does not work,

    Found this very good article on hdmi out if one is in the market for fpv goggles that uses hdmi in,

    The sad and complex state of video out on smartphones,
    http://agevik.se/post/58599484370/the-s ... martphones

    My own thoughts,
    Things are probably easier with a mhl using device. (should not really matter but it seams to, and mhl been around longer, "cave eat" is external power)
    If the resolution on the device is 16:9 you probably are better of avoiding black bars going from 16:10 filling the whole image and not have the need for some root app.

    And,
    I am probably heading for a new tablet purchase so I am up for suggestions on a 16:9 (1920x1080) not heavy, preferable 7"-8" fast one, and if somebody have tested out and it works with wifi to Phantom and using internet over 3g-4g simultaneously with Dji app that would probably be the "sweet spot" product :) (and one that works well with the Dji app in general)
    (my Nexus 7 will then be "inherited" within the family ;))

    Re: Cinemizer on Nexus 7 v2 via slimport - Does not work,

    My Question: (no.2 more inf., replay below)
    Reply from Ziess:
    Well the output is 1080p/60 Hz from the slimport as far as I have found, but nothing much to do, just hope some more will address this and maybe they make a change in the future to there firmware or the Nexus 7 to solve this.
    There is one more "venue" that I can try and solve this with a workaround, but I have not decided yet if I going to put any more money into current solution on a slim chance or simply invest in a new tablet.

    Anyway, hopefully this posts maybe will prevent some one from doing my mistake to go for this hardware combination.

    Re: Cinemizer on Nexus 7 v2 via slimport - Need of extra hw,

    So I did choose to explore the only other venue that I could think of to make this work before buying a new tablet or a phone .

    First,
    IMO Ziess support is useless and uninterested, first in my original problem and even asking for another specific hardware to use (Andriod) the replay was I do not know and that is it, I wonder why they even have this ask them thing on there homepage at all? At least this is my encounters and experience as of today with them.

    ---

    Any how,
    Doing some homemovie stuff since big LD onwards there was a time with considerable problems regarding EDID (extended display identification data) and there have been some device's that not defeating any protection but just clarify the dialogue and let you make sure what the hardware report what it is and what it is capable of.

    In this case we have the Zeiss with 1080p/60Hz and the Nexus with 1080p/60Hz it should work but it does not so I bought this product called Dr HDMI that can both extend signal and also report EDID of choice, so trying it with the built in choice of 1080p/60Hz in between it did work.

    The small "cave eat" is that the Dr HDMI dongle need external power so I fixed that with one small battery pack for mobiles.

    I will attach a picture with the sort of line of cables and hardware so you get a picture of it:

    So with Kit Kat 4.4.4.4 and Cinemizer with 1.1.8b and a Dr HDMI this do works for me and IMO the fix should be very simple for Ziess to implement or in Kit Kat because the rejection of the EDID could be in either end.

    Also with the 1920x1200 (internal nexus) to 1920x1080 (external on slimport) I am not bothered with the small black bars, can't actually even tell that they are there, so I have dropped the adjust the resolution part.

    OBS!
    The device cost some and I will not take any responsibility for the functionality of this solution, but as of now it do work fine for me.




    I did see searching through the forum when looking before for some new hardware to use before this solution that some one here do run with note 3 with a MHL adapter and Cinemizer, but double check that and as I wrote asking Ziess if a combination do work seams rather fruitless. Apple device users are well of on information, but not regarding Android devices.
