I have an issue which I cannot figure out.
Yesterday I updated my RPi3B+ to the latest kernel (Linux 4.14.62-v7+ armv7l) and firmware (#1134). Since then resolution on my VNC has changed to pretty small one (I was using 1280x720).
I tried to change resolution in raspi-config, rebooted the Pi but the resolution on VNC stays unaffected.
The thing is that it is a headless Pi so really don't know if the resolution affects also physical screen.
The question is how can i start troubleshooting? Do we know guys what config files are responsible for resolution setting? Any help appreciated a lot. Thank you.
