I'm unable to get realVNC to serve to a remote display in the resolution as set in /boot/config.txt
The 'usual' solution (modify /boot/config.txt) doesn't work...
Setup:
RPi3B+ with freshly installed OpenPlotter v1.0.0
I've enabled VNC and SSH access. I've also enabled the OpenGL v4-kms-v3d driver.
With a physical HDMI screen attached all works fine. When I use a vncviewer, I get the exact same desktop. As expected.
When I disconnect the HDMI screen and boot the RPi Headless, vncserver always gives me 1152x864. I want to change this to something else.
I've set the usual modifications of the /boot/confg.txt file. most notably:
Booting headlessly works fine, and when I log in via SSH and run tvservice -s to confirm the hdmi mode
vncserver and X are running:
But when I connect a vncclient it gets served a 1152x864 desktop
driving me mad. All the things I find online indicate it should work by modifying the config,txt
