    Right; I'd like to have the option to which I had with the PCH A-500 (I'm quite disappointed that I don't, but I can live with this limitation). Since my TV is at the optimal distance, as a videophile I might have liked to be able to continue to see the picture with optimal clarity.

    With most displays at 4K and now moving on to 8K I think there's a point where we need to let go of the idea of displaying at native resolution for SD, HD and FHD - and that point was perhaps 5-10 years or so ago.

    I know exactly what you mean though, but the resolution of current displays has made such a concept completely untenable and current upscaling technology, whether in the display or within the SOC of the source means that we just don't need to view such content natively any more - it really is that good!

    The only way to achieve what you want is to have a display native to each resolution, such is the scale difference between what's the norm (3840x2160) and the lowest denominator (720x480).

    Personally, most of my content is now 4K but I let the Zidoo upscale rather than the display since in my case it does a better job.

    Very interesting subject though :)

    Thank you very much, Mark! I was thinking that, with my 65' at THX Optimal Viewing distance (roughly 7' but I forget exactly) I might be very happy with a 1080p box (but you're right, likely not a 720p box). OTOH, I'm stunned by the improvement in upscaling from my 2008 Samsung to my 2021 LG. To the point where I must admit that I'm even happy enough with upscaled 720p content (and often not sure if it's 1080p upscaled).

    Even if I could do what I want, I'd probably not want to. So maybe what I want is simply me not letting go of the old days.

    I'll try letting the Zidoo upscale (which I achieve with that Match Resolution setting, right?) and see if I can see any difference. Thank you very much for bringing me into the present!

    No, if you set Match Resolution, you output at the native resolution and the display has to scale. Set Frame Rate Only and then the Zidoo will output all content at the resolution you set in Settings/Display/Resolution.

    When I do this, will Settings|Display|Resolution be irrelevant?
    Since in this case it's outputting the content's framerate (which one wants to = Hz), does one then set Settings|Display|Resolution to Auto? (I ask because the other Settings|Display|Resolution choices fix a Hz.) And does one want to "Lock Resolution"?

    You're overthinking this!

    Settings/Display/Resolution sets the resolution & refresh rate of the GUI.

    If you set it to "Auto" it will take the highest value allowed in the EDID - likely 3840x2160p 60Hz.

    Then Frame Rate Mode sets the behaviour of actual content.

    Lock Resolution is only to keep a set GUI resolution after a power down, so yes, leave that on.

    Ah, I see! I wish the Settings window had explained this is just about the GUI.

    In fairness, when reading your "****" I did get confused by the mention of the GUI, and in my confusion did wonder whether something in the Settings was just about the display of the GUI.

    Since I want to minimize resyncs, am I now understanding that I want to set Settings/Display/Resolution = the most common Resolution/Hz of the video content I'm browsing (in quantity over Samba, which is when when the resyncs drive me nuts)?
    Edit: Now I see that the Resolution/Hz of the content I'm browsing is all over the map, sigh.
    Now that I understand it's about the GUI not the video content that makes sense, but even then something like "Display Max" would be more accurate, and the word "Auto" helped me misunderstand that it was about something that changed, like the video content.
    Thanks man!

    That's the reason I set my resolution to 3840x2160p 23Hz and set Frame Rate Only in Frame Rate Mode.

    I also have HDR set to LLDV so everything is output in LLDV (obviously that depends if the display will do LLDV) so that way, since the majority of my content is 23.976fps, I only get resyncs on the rare occasion when something is 24fps and the extremely rare occasion when it's 59/60fps.

    I know what you mean about the GUI resolution, but it's not a "max" resolution since you can set it to 1080p and play content at 4K and if you don't set "match resolution" it's also the content resolution, so the description is correct because its effect changes depending on settings.

    I'm embarrassed that I've been so confused about this stuff. I just re-read the above and now understand that that Resolution setting doesn't only set the GUI parameters, it also sets what the Zidoo scales to if one calls on it to (with the Framerate Only setting).
    I don't know if you know that I was only referring to the "Auto" option (of the Resolution setting), not to the overall Resolution setting.
    Right now I've got HDR set to Auto. If I might want to change that to the LLDV setting, could you point me to where I can learn how to deal with figuring out if my display supports it?

    If you see an option called "Dolby Vision Low Latency (LLDV,YUV422,12bit)" in HDR settings, then the display supports it. If not, it doesn't.

    What's the display?

    I'd ordered a new HDMI cable, but today I find that turning the TV off/on is sufficient! That seems acceptable to me, since I've had to do that with other devices on a previous TV too.

    It's there!
    LG C1 OLED 65" (sorry to have only now populated my sig.)

    I feel too ignorant to decide to change HDR from Auto to LLDV. Are there reasons not to?

    I don't think so (a purist might disagree!) But try it and see - basically it uses the Dolby Vision VS10 engine to convert all content whether SDR or HDR to Player Led Dolby Vision - I like it - there's some Dolby secret sauce in there that works well for me ;)

    HDMI syncs on a change of resolution and/or HDR mode and/or frame rate. So by fixing the resolution and the HDR mode you are restricting the possibility of resyncs to frame rate changes only.

    I found that switching the TV on first, before the Zidoo (Z1000 Pro) ensured it was found straight away.
    When switching on the Zidoo first, it was "hit and miss" if it connected and needed to be switched off and on again. My situation may be different, however, as HDMI is via an AVRKey, that is left on.

    Thanks for the advice. Turning on the TV first definitely does not work for me but at least I am now thinking about the order. It looks like turning on the Zidoo first works more reliably for me.

    Have you made sure CEC is off for TV, AVR and Zidoo? This causes issues with a variety of manufacturers and HDMI attachments.....

    I only have the start up problem sometimes, probably because my setup usually starts the Zidoo first. I think that when I have the issue, maybe the TV starts up first. I only realise this now after reading your post and doing some tests. So I now have a 1 second delay after the Zidoo starts up and before the TV starts up.

    Thank you very much, Enet and Phil181!

    I haven't encountered a handshake again yet that turning stuff off doesn't resolve, but when I do I'll start experimenting with the order.

    Is there some remote control button (or way to achieve) 'Next File" functionality. For example while watching a TV series or browsing a folder via Samba.
