I’m trying to connect a Jonsbo D8 8-inch external monitor (1280x800) to my RPI4 running DietPI 9.8.
The monitor is detected properly by my laptop running Fedora Linux. Connecting to the Pi however doesn’t give any signal. I have succesfully used the hdmi output to my amplifier for audio earlier.
The cable i’m currently using is a new cable i’ve ordered from Amazon, it’s micro-hdmi to mini-hdmi. I have no other devices i can test that with other than the RPI4 and Jonsbo D8.
So far none of the changes have had any effect. I’ve tried hot and cold rebooting the RPI4, re-inserting the hdmi cable after boot, and powering the display on and off.
Does anyone perhaps have any suggestions what else i could try to get a signal on the monitor?
Thanks for the suggestions guys. I decided to return the monitor since it felt a bit risky to order more cables and potentially be stuck with a monitor i couldn’t use. Better safe than sorry, so to speak.
Next time i’ll try a monitor i will probably order one that is known to work well with the rpi4, just in case.
