HiassofT Thank you again for your great support. Here is the log: http://ix.io/3SST

3840x2160 30Hz is my standard. That works without issue for 10.0.0, 10.0.1, 10.0.2.

I tested now 1920x1080 with 30 and 60Hz. That works also without issue.

Thx

Thomas

HiassofT

thank you for looking at my problem again. I first adjusted the whitelist (see 2 pictures in the attachment). Then I changed the refresh rate to 60Hz (see attached image). I turned on debugging again, reproduced the error, and uploaded the log: http://ix.io/3SLQ

Hope it might help this time.

Thank you so much.

HiassofT AppleTV works with 4:4:4 YCbCr (see attached file).

Da Flex again:

I'm not convinced it's an AVR problem. I also use Apple TV. There I set the same resolution and screen refresh rate as on the RPi4. This works fine with the Apple TV.

Or do I have a problem of understanding?

Thanks

Thomas

Da Flex This not works for me. Because I had 4 different inputs on AVR and 2 outputs (TV and Beamer).

HiassofT Yes, I have the newest firmware installed on AVR. I'm not convinced it's an AVR problem. I also use Apple TV. There I set the same resolution and screen refresh rate as on the RPi4. This works fine with the Apple TV.

Or do I have a problem of understanding?

Thanks

Thomas

HiassofT That was a good idea

The TV was connected via AVR. TV-model: Samsung GQ49Q70RGTXZG, AVR-model: Onkyo TX-NR696. I connect the RPi now directly to the screen and it works fine. I looks like a problem by connect via AVR. I have the same problem when I switched the output on AVR to beamer. Hope this will be helpfull for you to find a solution.

Thanks so much

Thomas

I tested both:

1. "When the TV is switched off" should be set to "Ignore"

2. cmdline.txt: boot=UUID=1108-5701 disk=UUID=3542a3ff-9e05-4d2b-80ce-0438958f4de6 quiet video=HDMI-A-1:3840x2160M@60

3. combination of 1. and 2.

Result ist the same. I switched of my screen, wait 10s, switched it on and then I have no picture from RPi4. When I switch the refresh rate to 30Hz, everything works fine.

Some more ideas? Thanks.

Thanks for your answer and support. Normally I had switched off the CEC-adapter in the settings. But for testing now I switched it on. I don't find the setting where I can keep HDMI signal always on. Can you explain it little bit more. Thank you so much.

Da Flex The HDMI-cable is 2.1. I don't think that it has to do with cable. Because after rebooting the RPI4 it works. And also when I switch from 30Hz to 60Hz in the setting it works. Can I setup the whitelist manual?

Quote from HiassofT

busfahrer303 first add "drm.debug=0x04" to the end of /flash/cmdline.txt (after "quiet", all on the same line) to get some more debug info, then reboot and reproduce the issue.

After that ssh in, run "pastekodi" and post the URL you got.

so long,

Hias

Thanks for the quick response HiassofT

The Debuglog you will find here: http://ix.io/3S9v

Thanks

I installed 10.0.2 over the weekend. I still have problems with the 4kp60. I turned on the switch in the config.txt. Then I set the refresh rate to 60Hz in the settings. That works too and I have a picture. If I turn off the screen and turn it on again after 10 seconds, I no longer get a picture. I only get a picture again after restarting the RPi4. The behavior can be reproduced.

Quote from HiassofT

Please test again with a clean installation of the latest nightly image.

One of the video driver bugs caused the system to hang for a while, update/reboot in general works but could take several (3-10) minutes. If you pulled the plug in the middle of an update you may have messed up the installation.

so long,

Where can I get the "nightly image" for libreelec 10.0.1?

Quote from chewitt

Is 4K60 enabled? .. If yes, disable it and try again.

No, it's not enabled.

Hello,

I have yesterday Libreelec 10.0.1 cpl. reinstalled. Have previously had Libreelec 9.8.2 (I still have on separate card). I have with the new version problems with the image. It happens again and again that I get no picture after a reboot. Only after I disconnect the RPi from the power it works again. Sometimes not even then. The RPi is connected to an Onkyo receiver and from there it goes either to the TV or the beamer. Even when switching the AV receiver from TV to beamer or vice versa, I often get no picture. Only after I then completely restart it works again. Before with the 9.8.2 everything no problem. I have already tested various settings that I have found here or in other forums, unfortunately without success. Does anyone have an idea?

Thanks a lot
