VNC Resolution with AstroPi3 was created by Clive Davies

Hi,

I have used rlancaste great AstroPi3 script to set a new RPi and its working fine using local HDMI, but using it headless with VNC Viewer I cannot seem to set the display resolution so I can see the whole screen. I am using Windows 10 with a screen resolution of 1366x768 which is I understand limiting, but I would like to set the Pi display setting so I can ore. Using EKOS / INDI is near impossible over VNC as I cannot see the buttons for the windows.

Any assistance great appreciated.

You need to edit the file /boot/config.txt as root and uncomment the following parameters and give them these values:

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=23

The value of hdmi_mode will give a resolution of 1280x768 which may still be too large for your display. Please refer to the same /boot/config.txt file for other possible values of hdmi_mode. Don't forget to reboot after you make the changes.
