hello dom
i was wondering if you could help me with my problem. im making a test image generator for our company. an test image source that could be use using ang vga and hdmi output. ive heard about the vga666 and built one . it works fine.i tested it via vga at it works.but i would also like it to show my test image via hdmi. i dont need to go to my desktop. i made a script so that my pi would automatically load my script/test image without going to desktop.
But i noticed that if i make vga my default dusplay that my hdmi wont show anything anymore. Is there a way that i could just easily switch from vga to hdmi without changing anything (like pressing a button on keyboard or changing config.txt) every time i want to use my hdmi output?
thank you very much
