Hi, just bumping this. I guess the next thing I would try is to uninstall and reinstall MAME, which may mean finding a whole new version and redoing anything I've done to set up my games in this version.

Hi. So I was trying to get the games to display on the proper screen, and I caused another issue. I ran MAME in verbose mode from command prompt (all very out of my comfort zone), and I was in the MAME interface, and I went into some settings, and in a couple places I changed number of screens to "2" hoping that might help. Then MAME crashed and now it won't open back up and gives me the error discussed above: Unable to create the Direct3D device Unable to initialize Direct3D 9 Fatal error: Unable to complete window creation My .ini file is in the right folder. I tried changing video from "auto" to "opengl". Note I also changed some of the 0s to 1s based on the above screenshot. I also went and updated DirectX. Feels like I just need to undo that setting that I changed within MAME, but I can't get in there to do it. Running MAME257, btw. Unclear where that install file still is and too afraid to try to update these things. I had this all working but switched computers....

OMG.... CAPS?!?!? I thought I was being deliberate with everything. When I changed to all caps (DISPLAY4) it worked. I had to go back and turn Marquee screen to None in BigBox, and numscreens to 0 in mame.ini, but once I did those things it worked as desired. Thank you! Okay, now come find me streaming on twitch tonight....

I'm on night 3 of trying to solve this. I have launchbox on my laptop, hooked up to a TV screen. Running MAME. Everything has been running fine when I duplicated displays. I now want to extend displays so I can use the other screen. I set the TV to my primary screen in my Windows Display Settings. I set the Primary Display to Display2 within BigBox. When I open BigBox, it opens on the TV. When I open a game (have tried a few), it opens on the Laptop monitor... I've tried toggling on and off Marquee screen. I've tried changing the .ini file. I ran cmd and discovered my monitors were \\.\display1 and 4. I changed "screen", "screen0", etc. to \\.\display4. I tried changing numscreens to 2. I've restarted the computer. No matter what I've done it always opens the game on the laptop. I've read 2 threads on this forum, reddit, others, and have tried everything suggested. Any other ideas?
