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.

wizardly_jennings · October 13, 2024 at 12:22 AM

I made the 30Hz adjustment and rebooted and I'm still in the corrupted state. I'll go through the menus and see if I can find anything about rez upscaling but can I ask where in the debug output you were able to identify that behavior? Both out of curiosity and out of then being able to validate that I have disabled rez scaling.

**Da Flex** · October 13, 2024 at 1:50 AM

Last quoted code line seems to say that it's upscaled. Please correct me, if you actually get another resolution.

The log looks fine, just the harmless errors that I see all the time. So I think the TV can't deal with an HDMI param.

Try this (same as before, but without the "M"): "video=HDMI-A-1:1920x1080@60".

wizardly_jennings · October 13, 2024 at 2:48 AM

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

wizardly_jennings · October 13, 2024 at 2:59 PM

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.

I had a hunch that might have happened. If it's any consolation you're not the first sort-order victim

We already had it with the 2GB variant (see post #4). The 8GB issue is new here, since they've changed hardware.

HarryH · October 14, 2024 at 7:23 PM

Hi Da Flex ,

I expect also 4GiB/8GiB models in the future with the new chip revision. But after the post of chewitt I could see also the memory information in the logs. Maybe it's not the variant wizardly_jennings has ordered, but he use the 2GiB version, not a 8GiB model like he assumed.

wizardly_jennings · October 15, 2024 at 7:33 PM

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.

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...

RPi's have best software support among all LE devices. Just do QC after buying one.
