    Seems like the TV upscales the resolution (try to avoid that in TV settings). Try "video=HDMI-A-1:1920x1080M@30". I guess the TV will double the refresh rate automatically, so you still get 60Hz at the end.

    Ok, I just wanted to make sure there wasn't something easily grep-able to indicate rez scaling. You just have to look for "GUI format" and "Display" numbers having a factor.

    I dropped the "M" and it didn't make a difference. I'll post another debug log below...

    Also, fwiw, I moved the Pi over to the -- as the kids say -- "mid" Dell 27" monitor with the same results. So I kinda suspect the Bravia is not the root cause here.

    I would say perhaps I have a fault in the vid hardware except that Raspberry Pi OS is able to send X11 desktop output to both the Bravia and Dell w/o difficulties.

    Oh, fwiw, I don't think I mentioned this before...I've put the TV on the network and made sure it is up-to-date for software from Sony. One less variable.

    The RPi5 2GB model was launched shortly after we shipped LE 12.0.1 and it requires some specific mesa graphics patches that don't exist in the 12.0.1 release. Use the latest nightly from https://test.libreelec.tv/12.0/RPi/RPi5/ (scroll down) and it should work fine.

    Good eyeballs chewitt ;), this was already my first suspection in post#4. wizardly_jennings there seems something was going wrong with your first attempt with the nightly build. Please try again, like chewitt recommend and ensure the you grab the most recent version from below.

    Alternatively you can do that at the ssh console of LE12:

    Code
    cd /storage/.update
wget https://test.libreelec.tv/12.0/RPi/RPi5/LibreELEC-RPi5.aarch64-12.0-nightly-20241008-0803b93.img.gz
reboot

    As I've gone through each round of testing I've been doing a run with both stable and nightly. The results have been the same between versions each time. HOWEVER, it looks like the web site sorts ascending by default and I might/probably have been grabbing an old nightly.

    I just flashed and booted to https://test.libreelec.tv/13.0/RPi/RPi5/…-f5bd1a2.img.gz...

    AND IT WORKS!

    So I believe, once we got to using the nightly, this can be attributed to PIBKAC almost exclusively. In my defense, as such, I was bouncing between prepping a motorcycle for a rally, building a greenhouse, and this project depending on how overheated I was at the moment. lol

    I'm so happy this is sorted. I will continue to run the nightlies until the necessary drivers have landed in GA and then I will settle on stable.

    Thanks a ton, y'all. My kid will be happy because it seems like tonight might be a movie night. :D

    Wait...what?!

    No, you are correct. This is a 2GB. I'm sure I ordered an 8GB because my 2GB Pi4 has been OOM'ing and it was worth the $30 difference to not have to deal with that crud. The invoice says 2GB though.

    ?(

    What a cluster.

    Anyway, I appreciate the help, y'all. I hope this thing will be ok with 2GB because I don't feel like going around and around with Cana on this. Particularly after the SD card reader they shipped with the kit was so unreliable.

    This plus my PiKVM having a hardware failure after only a few months. This might be it for me and Pis. :cursing:

    I guess it's off to Lilliputing to see what other SBC form-factor comes close for power consumption and ecosystem. I keep seeing other ARMs popping up...
