TV Connection keeps resetting on U22-XJ

I have managed to upgrade, FOTA is now working and I am running v006 of the firmware.

I can also say that it has not fixed the issue. I have changed the setting to Adaptive HDR, but cannot see any benefit.

in fact its worse now, my Minix is totally losing the signal to the TV every now and then, the TV is displaying the Splash Picture showing the message "No Signal" which is what I get when the Minix has been switched off.

I have tested this with a Neo X8-Plus which works fine and also change the HDMI cable to ensure there is nothing wrong there.

My TV is a LG 55UH7500-CA running the latest version of its firmware, not really changed any settings on the TV.
 
So not so much seeing the HDR sign in the top left of the screen any more, its the screen flickering as if its lost the signal for a split second, goes blank for that time and then the picture and sound come back.

Can you confirm the bit depth, 8, 10 or 12 bit (24,30,36) aswell as what do you see for chroma subsample 420,422 or 444? I have an lg tv but i only see the blinks with AFR option with the 36bit output.
 
Sorry, where are these settings, I have looked but cannot see ?

Yeah sorry for causing any confusion.

Do you have a receiver between tv and minix Or the minix directly plugged to tv? If its the later then im not sure how to find what type of bit depth is being set in your setup. My guess would be 420 would be 8(24), 422 would be 10(30) and 444 would be 12(36).

I have a receiver and this info is found in its info menu. I suspect that our lg tvs dont like a 36bit output on minix and that is what causes the blinks. (On the other hand shield tv has no problem with 36bit on the same tv)

this is a good article has some color depth explanation : https://www.benq.com/en-me/knowledg...oes-monitor-panel-bit-color-depth-matter.html

If anyone else can explain how to check the bit depth without a receiver please respond to op here it would help.
 
Try turning OFF these 2 setting:
1.Auto switch to best resolution
2.Color depth settings

see if that makes any difference, if not then try 1080p resolution and test if the blinks occur.

i think you might have tried a different cable (hdmi 2.0 high speed cable) if not give this a try.

lastly, try other hdmi ports on the tv see if the experience change with other inputs.

Setting the first two options you said, have made thing a lot better.
I had already changed the cable and swapped the HDMI ports around.

Unfortunately, not all AVRs include an actual "information" GUI/menu capable of displaying various details of any currently playing media anyway, (for those that do use them)! Some just have the basic info on the front panel itself, while others like yours have some kind of OSD with varying degrees of extra info depending on the specific make/model :).

Some TV's can also include a similar feature but the same applies.

Otherwise, to my (limited ;) ) knowledge, options for checking the info of any currently playing media from an Android device like the U22 are very basic. If using Kodi, for example, you can press "O" if you're using a keyboard or a remote such as the Neo A2 Lite/A3 which will bring up Kodi's player process info if that helps a little?

Additionally, if you have a typical keyboard connected to your U22 you can press ctrl + shift + O which will bring up the "player debug" information too. (I've mapped the player debug info to the "apps" button for an A2 Lite while I've been testing CoreELEC with a U22 recently as obviously the apps button has no function outside of Android. A different key could be mapped for use in Android too although the info is very specific & ultimately intended for troubleshooting/debugging issues such as bottlenecks.)

One can view more information on what these features (player process info & player debug) will actually tell you in the respective Kodi wiki....

https://kodi.wiki/view/Player_process_info

CoreELEC (default skin), as another example, also includes a little extra (output) information in the player process info that includes...

Display mode, (the actual display output & FPS).

Pixel format, (output not the decoding). I.e. 10 bit, YUV 444 or 12 bit, YUV 422, etc.

EOTF & gamut. I.e. SDR BT.709 or HDR BT.2020 as applicable.

Different Kodi skins available from the official repository may also have extended information scripted in to the player process info as well. (Obviously that's a case of personal trial & error, searching for info specific to the skin or looking into them as to what info the author has scripted in to be displayed.)

Android VLC can also display some "now playing" info that Kodi doesn't have but that too is fairly basic.

Unfortunately, luxuries such as Windows (or Mac) VLC Player that is capable of providing all sorts of extra information while media is actually playing, or that has an entire suite of highly advanced controls just isn't available for leaner OSs like Android, (yet at least). One day, improbable, but who knows :)?
