Is there a way to enable a higher resolution remote (e.g. Xvnc) display with nothing plugged in the HDMI port.
I prefer to run my rock pi 4B headless, but would like 1080p graphics.
On the raspberry pi, I can just set some config.txt hdmi settings to set the resolution without a physical HDMI monitor plugged in. I am unsure if there is something analogous I can do on the Rock Pi 4B ?
Thanks
