no video on bootup

Post by mathewbeall » Tue Jun 12, 2018 4:01 am

Hi Folks!

Weird question here - I have the RaspberryJamma and arpicade (latest version) and I have tested it on two monitors - both CRT's (13" and 25") and it worked great.. I *think* the initial boot screen is interlaced?

Anyways - I just got a 19" visiontek LCD and i get zero boot screens, but if I hit a button to play one of the games the monitor comes alive.

What do I need to do to get the menu to show up appropriately on the arcade LCD?

Thanks!

Matt

Not familar with the Visiontek but if it works at 240p when you boot a game running the whole system in 240p is probably the easiest way to go. As it's an LCD screen if it supports 480p the high res settings may actually look better though, I'm not sure.

If you have no picture in the menu to use the service menu to change settings you can use you desktop PC. You will just need to change the video mode in /boot/config.txt to have the system boot in 240p, with the latest version of ARpiCADE you shouldn't need to do anything else.

EDIT: yes using the default settings the system boots in 480i interlaced mode for the extra screen resolution in the menus.

Thanks - I uncommented a setting in the config file to get it to show up:

hdmi_safe=1

After that - all works fine.... strange!

Whoops - Vision Pro (Suzo Happ), not VisionTek... :)

Not certain but I think hdmi_safe forces 480p as most modern screens will accept it. Sort of surprised it all works just changing that, I don't use that setting but if it works it works.
