I did a test with the newest image on my opi-one-plus, and still have the same problem (black screen). I tested multiple cables on my TV and monitor (all are working fine with various pis, odroids etc.), and I finally had a signal on the monitor (but not stable). Funny thing is: my TV has multiple inputs and it switches to the input the opi is connected to, so there must be at least a weak signal.

My question is: can you make the HDMI-signal stronger? Since the desktop image of Xulong is working fine, I assume they use a stronger HDMI-signal.

Can you test this board on any other TV/monitor, preferably with different native resolution (doesn't matter if lower or higher)?

I tested it on a different 1080p TV, and it works (at least the initial LibreElec wizard is displayed). So something on my Samsung is confusing the video driver.

BTW: could it just be a hardware problem? I'm currently downloading the Debian Desktop provided by OrangePi itself, just to make sure that the HDMI interface has no problem.

Well, the Debian Desktop works with 1080p on my 4K monitor. So it doesn't seem to be a problem of my board.

I tested it with my 4K monitor. The HDMI input is only 1.4, so it is 4K@30Hz while my TV is 1080p@60Hz. The monitor displays the LibreElec boot-logo, but shortly after that the monitor complains about no signal. I will test another TV (also 1080p, but other make) tomorrow at a friend.

I will prepare the logs and send them tomorrow.

Here are the logs.

gamma-271 Can you test: libreelec-h6.arm-9.80-devel-20190701201203-8a8e6a1-orangepi_one_plus.img.gz ?

It seems that Mali causes system lockups if it doesn't run on lowest setting... I'll need to investigate this further.

Sorry for the late response: I've been offline for a couple of days. With this image, nothing has changed. I will prepare the logs and send them tomorrow.

The system does not seem to lock up, it just doesn't display anything. I even noticed that when I press the power-off button on my TV-remote, LibreElec also shuts down. So CEC seems to work (which only is a hint that the HDMI-connection is there and working).

Yes, but it will take until Monday, because I'm currently not at home.

Here is the kodi.log

Can you also upload Kodi log

Yes, but it will take until Monday, because I'm currently not at home.

gamma-271   Adjames089 Can both of you provide output of edid-decode /sys/class/drm/card0-HDMI-A-1/edid, when TV with issue is connected?

Included here is the output of edid-decode.

I'm running this on the Orange Pi One Plus H6

Which build do you use? Are you using a 4K TV?

My TV is 1920x1080, my monitor is 4K. IMHO it does not make a difference. Same messages even if I don't attach any cable.

Is this of any relevance: Can't get HDMI out on OrangePi One on sunxi-next · Issue #290 · linux-sunxi/linux-sunxi · GitHub? I know that the issue is about Orange-Pi One, and I have the One-Plus, but the symptom is the same.

Ok, thanks for the instructions. Output of console-log is included, in addition output of dmesg. I also tried to boot the system attached to my monitor instead of the TV. On the monitor I at least see the initial LibreElec logo.

Hi,

I just tried the OrangePi One Plus image from 25.06. but it does not boot. Seems to be a problem with hdmi:

I could also provide the complete uboot-log.
