Convergance Dock HDMI resolution: - bceverly - 08-09-2021
Hi,
I have a PinePhone convergence device and dock and when I plug in, the keyboard and mouse work fine but I get no output on the HDMI display. Is there a maximum (or minimum) resolution that must be supported? I'm plugging in a Dell Ultrasharp 27 (U2720Q) monitor (specs) which is a 4k panel.
Thanks!

first you have to flash the working firmware in the ANX7688 chip
https://xnux.eu/devices/feature/anx7688.html
https://xff.cz/git/linux-firmware/plain/anx7688-fw.bin
you copy the file with sudo into "/lib/firmware" and you flash it as root giving su with password root and then the echo command
`sudo cp anx7688-fw.bin /lib/firmware`
`su`
`echo 1 > /sys/class/typec/port0/device/flash_eeprom`
after echoing the value "1" into the file "/sys/class/typec/port0/device/flash_eeprom" the flash operation starts and after some seconds the operation is complete and you get back the terminal
giving `dmesg` you will get all the kernel messages of the operation at the end of the output in the following form
[timestamp] anx7688 1-0028: eeprom wr [2+16 bytes in hexadecimal format]

Thanks for the reply!
I have flashed the firmware successfully from looking at the dmesg output. I've rebooted the device and yet I still cannot get output on the monitor I have plugged into the HDMI port.
Any further steps I need to do in the UI on the phone perhaps to enable the external monitor?
Thanks!

I just tested it too and it doesn't work. I searched and as I can understand you have to detect and activate the monitor, in classic X it would be done with xrandr, on Pinephone it depends on the distro and if it is using wayland as with Plasma, if I solve it I will comment here.

Did you get this to work?
