Hello,
now my G2 Saturn is running much better with piHPSDR. I am just asking myself whether ist is possible to duplicate the 7" screen to a monitor? Did anyone connect a separate Monitor to one of the HDMI outputs so far? Do I have to change any settings for that in the pi setup (e.g. preferences)?

Re: G2 with diplay using HDMI output
I now have the same Waveshare display as is shipped with a G2, so I've been able to investigate this.
The HDMI output is not disabled by default. You can enable it by the following edits:
(please be careful - this file will be intolerant of errors!)
open a console window
type: sudo nano /boot/config.txt
find the 2 lines starting #hdmi_group=1
remove the hashes (which comment out the line) and make them read:
hdmi_group=2
hdmi_mode=4
(that will enable hdmi output 1)
use ctrl-o to write the file (it will ask for confirmation) then ctrl-x to exit the editor
reboot: you should now have both displays
You will need to use preferences -> screen configuration to get them the way you want!

Re: G2 with diplay using HDMI output
Hi Laurence,
at startup I see the raspberry pi start screen only on HDMI, but only for a very short time. After that, I only see booting and starting of the application on the touchscreen, as before. HDMI monitor is not active any more (power save).Display->Preferences shows HDMI1. But I cannot select any submenues. I am using a monitor with dispay port input and use a converter cable. What I will check next is connecting a HDMI Monitor without converter cable.
