It's supposed to ask you which output will be used for CRT, and then select a monitor type. Connectors that have to be forced to ON are turned to on before any selection happens. Can you provide the file located in /home/arcade/shared/logs/groovy.log ? (or could be /home/arcade/shared/log/groovy.log)
It should even say "Turning <connetor> to ON as required"
I'm not sure where to find this log file, this is all while booting off usb so nothing has been installed to any drives. I cannot find any log files on the usb key either.
I tried again, this time at boot with my LCD plugged into motherboard vga, I selected 15kHz, then I promptly unplugged the monitor.
I figured if it does not detect a monitor on that port it would force the analog DVI-I on my video card.
So again, it went through all outputs, when it forces analog on DVI-I I get a screen on my arcade monitor. I select OK, but after it finishes with video port scan the screen stays black.
I hit enter a couple times hoping something would happen but nothing does.
Something interesting I did find though, when I hit the power button for the computer to power down or reboot so I can try again, I get the groovyarade splash screen popup on my arcade monitor.
