Support for multiple screens on Windows

[gpapin]

Hi,

I'm wondering how do you handle multiscreen configuration ?
Are you setting the same image on different screen or can you assign an image as a wallpaper for a particular screen (or desktop in case of osx).

I can identify 3 use-cases :

• Set genericWallpaper.jpg to screen all screen A,B,C
• Set panoramicWallpaper.jpg to be a single image covering screen A,B,C
• Set wallA.jpg and wallB.jpg to respectively cover screen A and B

Currently I'm just setting the first screen. I'm not on a multiscreen config, so wasn't a priority.

I'm on Ubuntu, with a multiscreen configuration and wallpaper.set set my wallpaper on both screens (first use-case).

@dorian-marchal Yeah, it's hard to preserve the same behaviour cross-platform. It only sets the wallpaper on the first screen on OS X and Windows. No idea if there's any way to do the same on Ubuntu. https://github.com/sindresorhus/linux-wallpaper/blob/master/index.js

I like it this way, I think this the desirable behaviour (unless wallpaper offers a way to change both screens independently).

[sindresorhus]

@dorian-marchal Yeah, I guess I could make that default for all platforms for now, but not sure, people in sindresorhus/macos-wallpaper#2 seems to think differently.

@sindresorhus, I don't think you can have different backgrounds on Linux (Ubuntu) on different screens by default, at least not without using an external tool. It's always going to use the same one on all screens.

Support for multiple screens was added for macOS in v4.

Apparently, in order to set wallpapers for multiple monitors images must be combined into one and result wallpaper should be tiled.
