With the problematic screen connected to the HDMI0 port (next to the USB-C) please post the content of the /var/log/Xorg.0.log from fresh start. This would show modeset and perhaps failing edid.
Hi @nerd , I just talked to my friend and he said the problem was the HDMI cable. He said it’s working now. I guess you need a good HDMI cable to make it work for the Raspberry Pi. How weird that the bad cable worked with Windows/PC but not Volumio/RPi.
By the way, I just want to confirm and second @dewen that the official 3.703 cannot perform an OTA update to version 3.733.
ook, we seem to be making some progress, commenting out the current display parameters from userconfig.txt and adding in the dtoverlay parameters yeilded good news and some bad news.
The screen saver now functions as intended, BUT their is a wide black band around the borders of the screen producing a much smaller and unsightly image.
What to do??
I’m new to Volumio and troubled by my recently bought display - Waveshare 11.9 HDMI in a casing via HDMI on a rpi 4b. After several tries and useful entries from the forum I still have the problem that the picture is off (see attached photo) - so it is not filling the screen. On the right side is a black gap and on the left side is some stuff missing from the plugin.
How can I change the position of the plugin/ picture?
You wrote that the display in question is connected via HDMI, but you (also) have dtoverlay=vc4-kms-dsi-waveshare-panel,11_9_inch,rotation=270 in “/boot/useconfig.txt”. So just for clarification: Is it an HDMI or DSI display?
You might also try the following settings from Waveshare’s wiki (for the touch screen variant of the 11.9" HDMI display - don’t know if this is relevant):
I had had these entries before, but found some different settings in the community (the ones that are and in the “/boot/useconfig.txt” now). The new entries didn’t change anything with my problem so I left the “new” ones in.
I am running the Free version of volumio, and have successfully enabled the OLED with the spectrum.
I would like to use the touchscreen 3.5 display, but when loading the plugin, it says that I cant use it if HDMI is an option…so, how do I do this? Sorry for Noob question
