Multi-screen support

[Ottoguy]

So I’ve used Dolphin with virtually no problems for a while, but there’s one thing I don’t know how (or if) I can fix. My main monitor is 1920x1200, while my two secondary monitors are both 1024x768. I’m thinking mostly about Mario Kart Wii, but possibly other games as well, about what I should do to make my secondary monitors display one player screen each, and have the main monitor display two player screens. Or if that’s not possible, what I should do to have one player per screen. Any help is appreciated!

As of right now I can't even figure out how to make it work on even 2 monitors. Using latest development build, Windows 10, Intel i5 4630k and GTX 770.

There isn't really any way you can do this. You could do it in Double Dash, since that supports LAN play and you can run 3 instances of Dolphin (1 per monitor). I'm not entirely sure how you configure LAN to work properly though, aside from it only really working on Linux.

So if a game does horizontal stacking, and works well with the widescreen hack, you can enable the widescreen hack and stretch to window and get a super wide window that can span between the displays, then position the window so the dividing line is between the displays and just like that, you have one player per display!

However, almost all GameCube games (including Double Dash) do vertical stacking, which complicates this a bit. The "widescreen hack", despite the name, will expand the game to whatever aspect ratio you want, so you can expand the vertical height of the window so there are two 16:9 windows stacked on top of eachother. You'll then need to reposition the monitors in windows to a vertical stack, and then position the window between them like before. It's weird, but, doable.

So this all of this depends on the game's compatibility with the widescreen hack of course, and it's a bit complicated to set up and use. But, it's flexible enough that shenanigans like this are possible!
