    In fact, they encounter the exact same number of bugs even when the version for them comes out...

    This worked well with the Z9X and its higher-end models. It's less effective with the 8K series. However, owners of the more expensive 8K models experience fewer playback issues than those with the lower-end models.
    Perhaps due to the additional RAM, or perhaps due to the faster RAM.

    Thank you...
    So, if I understand correctly, setting it to 4.2.2 12-bit means that Zidoo adds “layers,” but it's lighter and uses less bandwidth... whereas 4.4.4 10-bit takes up more bandwidth but ultimately puts less strain on the TV's processor because it has to do a lot of processing and sorting to switch back to 10-bit... This is interesting because I have the impression that 10-bit does not cause a reboot, whereas 12-bit does (I've done so many tests in every direction that I'm not sure anymore...).
    What was certain was that the “standard” and “optimal cinema” modes significantly reduced reboots... communication between the TV and the Zidoo (EDID info) is more stable... however, if the Zidoo is crashing and reboot, the tv's EDID it perceives from the Zidoo is no longer correct... I no longer have 12-bit, but 8-bit, no more Dolby Vision...
    To get the right EDID back, I have to turn the TV off and on again.

    Trying to find out...

    Not really - In a 4x2 pixel matrix, all modes contain luminance information for all 8 pixels. But only 4:4:4 has colour information for all 8 pixels too (so all 8 pixels can be different colours) - so it's lossless like RGB.

    4:2:0, which is how content is actually encoded only has 2 colours per 8 pixels and 4:2:2 is a halfway house with 4 colours per 8 pixels like this:

    In reality this doesn't really matter because the pixels are so small, even at SD resolutions.

    So when you're dealing with a 4:2:0 encoded source and upscaling to 4:2:2 or 4:4:4, assuming no interpolation, you are still passing the same information, only using more bandwidth because each pixel is encoded, like this:

    upload_2026-1-30_9-14-19.png
    So you can see that there is no advantage to the picture between 4:2:2 and 4:4:4 for a non interpolated 4:2:0 source. However displays process them differently and there can be advantages to using 4:2:2 especially if you use a video processor. But as a rule of thumb, it doesn't really matter other than bandwidth. 4:2:2 is unique in that you can increase bit depth from 8 to 10 to 12-bits and not increase bandwidth, but again this is irrelevant because 8 and 10-bit 4:2:2 are not supported in HDMI.

    To ge back to what's happening with your setup - goodness knows!!!

    @Markswift2003 :
    Okay...I understand, but doesn't sending 4.2.2 12-bit make the TV's processor work harder than 4.4.4 10-bit...? Because the panel is a 10-bit panel...
    Regarding my TV, you always say that CEC is the devil's work... well, I would say that Philips TVs are the devil...
    I really regret this purchase, not because of the image quality, but mainly because of its AVR management and what is connected to this AVR + If I disable Easy Link (CEC), I can no longer have ARC or eARC...
    In any case, the standard or cinema mode, with the 10-bit setting, has stabilized my device chain....it's not perfect (as with my Panasonic) but it's much better...
    I think the fact that it's Google TV as the OS may be part of the cause of the problem.

    If I'm honest I don't know - but the bottom line is if 10-bit is working for you, use that, because there's no trade off at all.

    Perhaps we need a poll to see who's had it :D

    Is it via OTA? No diff_file?

    OTA

    I'm not from the hdmi consortium but
    switching from atmos to stereo (etc) without a hdmi handshake would be marvelous.

    is that so? i did not get that pattern reading the various feedbacks

    In what scenario? Audio switching does not cause an HDMI sync.

    This is my observation. You may have different observations and different opinions.

    MP8.0 is doing so or something similar after every multichannel track.
    it only plays gapless on stereo or sacd.
    If it's not due to a hdmi handshake then why?

    I know my avr does not have QMS (its a hdmi 2.0 device).
    I was hoping a new avr ( with qms) would do the trick.
