@mitu said in Getting picture when 2 screens are connected. 7" screen and 27"monitor:

I've tried swapping the cables, and it worked from the first try.

I now have picture on the 7" screen, which is now connected to hdmi1 and when I connect the 27" monitor to hdmi0, I get picture on the monitor. The 7" screen then displays a rainbow color screen and then goes blank.

The 7" screen only displays the launching screen, when I play a game.

I immediately tried an arcade game, the launching screen displayed, but then went back to the main menu.
I've tried other consoles, they all seem to work.

I've tried 2 other arcade games, which seems to work.

Coincidence or not, the game I tried first has a bezel overlay.
Maybe the monitor can't handle that for some reason ?

I will disable the bezel and see if it runs then.

@sleve_mcdichael I just figured it using rasp control app.

@kingcosmuder thats all i got running the command however i tired some dreamcast using redream and both games i tried, sonic adventure and marvel vs capcom 2 both ran 60 fps consistently so i believe its working now

@Bernie @sliderem Hello, My Pandora 3d controllers does not detect by raspberry pi4. I have installed Sanwa joysticks in my Pandora 3d. Also added usbhid.quirks=0x16c0:0x05e0:0x040 inside cmdline.txt. Do you have any idea? Is this because of my Sanwa sticks on pandora or should the Pandora ID remains same after joystick replacement? Really appreciate any suggestions.

@JimmyFromTheBay said in Turrican (hurricane clone) black screen:

[EDIT: just dumped all the files from 5.2 into /home/pi/RetroPie/roms/ports/sorr and it works a treat now.]

Glad you got it working, if any of the ports dont work, then they need the data files from another source, which you are on your own to provide.

Here is the link to my post here about all the scripts in Extras

post your questions and findings there, so everything is in one place

@dankcushions thanks
