Running with -video d3d -numscreens 2 I get Unable to create the Direct3D device <88760868>

Using opengl everything works as it should.

I'll have to disconnect everything here and reseat all the connections to see if it's a specific fault here on my end.

Interesting, I used to get the exact same error code if I tried to Alt+Tab from full screen MAME in D3D mode (or was it Alt+Enter that caused that? I forget), it used to require a force kill via Task Manager (or a Ctrl+C in the command line) as the error dialog would repeat infinitely. It didn't happen in OpenGL.

I might be able to look into this at some point, if I'm able to reproduce it on my dual-screen setup.

Could anyone try this, with artwork DISABLED.
I remember something from Jezze, that Dual-screens dont work with artwork enabled.

Good call, u-man. Now that you mention it, I vaguely remember something similar!

New tests with MAME with d3d and Dual Screen:
1. Run verbose under CMD window as instructed. It results in message: "Unable to create the Direct3D device (88760868) "
2. Disabled Artwork > no changes. Same bug
3. Windowed mode > IT WORKS

My opinion so far after tests: looks like occurs when changes the aspect ratio on full screen mode and dual screen simultaneously. Or could be the UI using natively OpenGL and crashes when changes to D3D ?
Didnt see relation with artwork handling.
