如果您因为讨厌 Windows 8 而仍在使用Windows 7并且使用多个显示器，那么您可能会遇到无法为每台显示器使用不同壁纸的限制。Windows 8 实际上为双显示器或多显示器设置(monitor setups)提供了很多很棒的功能，但在它们修复整个Start Screen/No-Start-Button问题之前，人们不会很快迁移。
幸运的是，您可以采取一些措施来纠正Windows 7中的这个问题。我将引导您了解不同的方法，从Windows 7中的一个简单小技巧开始，它不需要您安装任何第三方软件。其余选项是免费软件或商业应用程序。
方法 1 – 创建更大的图像
如果您有多个使用相同分辨率的显示器，那么您实际上可以创建一个图像，该图像是所有显示器组合的宽度，并将其用作墙纸。例如，如果您使用两台分辨率为 1600×1200 的显示器，则可以创建一个 3200×1200 的图像并将其加载为背景。
您唯一需要做的就是选择平铺(Tile) ，它将跨越屏幕上的图像。如果您有三台显示器，那么您将创建一个 4800×1200 的图像，依此类推。
现在，如果您的显示器由于显示器不同而具有不同的分辨率，那么您可以使用类似的技术，但您必须调整对齐方式才能使其正确。您仍将图像拼接在一起，但您必须在图像的底部留下一些黑色或白色空间以使它们正确对齐。
InterfaceLift.com是一个很酷的网站，可以帮助您查找多屏壁纸。或者您可以找到您需要的确切分辨率的壁纸。在这方面，这是一个非常有帮助的网站。
方法 2 – 双显示器工具
一个名为Dual Monitor Tools的免费开源程序(source program)非常适合在Windows 7中使用不同的背景。
您可以使用它将一个图像分布在多个监视器上，也可以为每个监视器使用不同的图像。该程序可让您在实际设置壁纸之前调整图像并预览更改。如果一台显示器是横向的而另一台是纵向的，它也可以处理。
该程序还具有许多其他功能，例如使用热键和双启动器管理窗口的交换屏幕(swap screen)，它允许您使用热键打开应用程序，然后在特定位置的特定显示器上打开。
方法 3 (Method 3) – DisplayFusion、UltraMon、MultiMon
多显示器软件阵营(multi-monitor software camp)中似乎只有几个玩家，它们分别是DisplayFusion、UltraMon 和 MultiMon(UltraMon and MultiMon)。DisplayFusion 和 MultiMon(DisplayFusion and MultiMon)都带有免费版本，可以实现在Windows 7中设置不同壁纸的目标。如果您想要它们包含的所有额外功能，您可以购买付费版本，但出于我们的目的，这不是必需的。
幸运的是，我已经写了这三个程序的评论：最佳双显示器软件(Best Dual Monitor Software)。真的很难说哪个更好，因为他们都做得很好。
当然，就像我之前提到的，在Windows 8中，您不再需要担心这个问题。现在，您只需右键单击图像，然后选择要应用该背景的显示器即可。
如果您知道其他方式或使用不同的程序在Windows 7中设置不同的背景，请在评论中告诉我们。享受！
Setup Different Backgrounds for Dual Monitors in Windows 7
If you’re still using Windows 7 because you hate Windows 8 and you use more than one monitor, you’ve probablу run into the limitation of not being able tо use a different wallpaper fоr each monitor. Windowѕ 8 actually has quitе a few awesome features for dual or more monitor setups, but until thеy fix the whole Start Screen/No-Start-Buttоn issues, peoplе аrеn’t going to be migrating anytіme soon.
Luckily, there are a couple of things you can do to rectify this problem in Windows 7. I’ll walk you through the different methods, starting with a simple little trick in Windows 7 which won’t require you to install any third-party software. The rest of the options are freeware or commercial applications.
Method 1 – Create a Larger Image
If you have multiple monitors that are using the same resolution, then you can actually create an image that is the width of all the monitors combined and use that as your wallpaper. For example, if you are using two monitors with a resolution of 1600×1200, then you can create an image that is 3200×1200 and load that up as the background.
The only thing you have to do is to choose Tile and it will span the image across the screens. If you have three monitors, then you would create an image that is 4800×1200 and so on.
Now if you have monitors with different resolutions because the monitors are different, then you can use a similar technique, but you’ll have to play around with the alignment to get it right. You’ll still stitch the images together, but you’ll have to leave some black or white space at the bottom of one to get them to align correctly.
A cool site that helps you find wallpapers for multiple screens is InterfaceLift.com. Or you can find wallpapers for the exact resolution that you need. It’s a very help site in this regard.
Method 2 – Dual Monitor Tools
A free and open source program called Dual Monitor Tools works really well for using different backgrounds in Windows 7.
You can use it to spread one image across multiple monitors or you can use a different image for each monitor. The program lets you adjust the images and preview the changes before you actually set the wallpapers. It can also handle if one monitor is landscape and another is portrait.
The program also has a bunch of other features like swap screen for managing windows using hotkeys and dual launcher, which lets you open applications with hotkeys and have then open on specific monitors at specific positions.
Method 3 – DisplayFusion, UltraMon, MultiMon
There seem to be only a couple of players in the multi-monitor software camp and those are namely DisplayFusion, UltraMon and MultiMon. Both DisplayFusion and MultiMon come with free versions that can accomplish the goal of setting different wallpapers in Windows 7. If you want all the extra features that they include, you can buy the paid versions, but for our purposes it’s not necessary.
Luckily, I already wrote a review of these three programs: Best Dual Monitor Software. It’s really hard to say which one is better since they all do a really good job.
Of course, like I mentioned before, in Windows 8, you no longer have to worry about this problem. Now you can just right-click on the image and choose which monitor you want that background to apply to.
If you know of another way or use a different program for setting different backgrounds in Windows 7, please let us know in the comments. Enjoy!
