I have a Xiaomi mi laser projector running android tv, today an update started (without even asking permission).
After that I had some problem with the audio from the hdmi input, after a while of messing arounf with no success I turned everything off and came back some hours later.
At this point not only I don't have audio but also video is missing.
The issue is not in the cable or the source of the hdmi (i tested them and those are not the problem)
I even whent for a factory reset with no luck. Has anyone experenced this?
[Edit] I posted a followup to this that you can check up here I would suggest you to post any updates there so we can gather informations in a single spot
[Edit 2] Here is the step by step guide on how to fix this issue, the fix comes from u/hockerz that contacted xiaomi's support. I take no responsibility for any damage to your belongings, here there is just what I did and what worked for me.
What you need:
How to prepare the usb stick:
How to update the projector:
The projector should now be in update mode, you should see the update bar moving, you can now relase the two buttons
This remote seems to check a lot of boxes. Just wondering your experiences. The pairing from the user manual looks a bit specific to the box. https://fccid.io/MG3-R35602/User-Manual/User-Manual-4107956.pdf
Good morning, everybody.
After various tests, I just found out that the AndroidTv boxes (especially the Mibox S and Nvidia Shield for what I tested anyway) didn't really have 4K-UHD with their HDMI interface.
Indeed, I just bought a 4K Wemax A300 video projector. So I did some calibration tests.
All my calibration tests on the stitching (4K or not) have been done from this video: https://www.youtube.com/watch?v=chuEXqVBGxE
You can see a download link at the bottom of this post.
To quickly explain how the benchmark work :
The lines in the videos are thin and close together. There are 9 lines (or columns). As long as you can distinguish the 9 lines, the display is good. The number you see has to be multiplied by 100 to get the total number of lines. So if at 20 I always distinguish the 9 lines. That means that my display can at least display 2000 lines of pixels. I remind you that the UHD 4k is 3840 columns and 2160 lines.
(I'm sorry, my pictures aren't very clear. I only have a smartphone to take the pictures. But good-looking or not, they're enough to prove my point.)
With the same settings, the same HDMI-output and with the same HDMI cable, I get different results, while all my players are supposed to be 4K.
So on this video :
On this one there are a few lines but they are difficult to distinguish : http://imgbox.com/gygHqU5l
On this one, there is no line at all : http://imgbox.com/R2MHlNGw
On this one there are a few lines but they are difficult to distinguish : http://imgbox.com/hzvhYW5J
I have of course in the parameters of Mibox S and the Nvidia Shield put in parameter 4K-60hz, and I also did the tests in 4K-30hz and 4K-24hz and 4K-50hz with always the same result.
So my conclusion is that at least the Mibox S and the Nvidia Shield don't send true 4K, but only 1080p.
Maybe it's my equipment that is faulty, or something I missed.
If not, I make the hypothesis that AndroidTV is the cause of the problem and not the hardware.
That would mean that AndroidTV doesn't send real 4K with its HDMI interface.
Can you also check at home?
Here's the downloadable link to the video :

If someone can test with the new shield and the Fire TV 4K too. If we get the same results with these boxes, I think we can seriously deduce that it's Android TV that badly handles 4K in HDMI output.
