However, I personally never let Windows decide which power profile I want, and I fully customize the power options every time I reset or reinstall Windows.īecause I find Windows preset power profile values to be rather flawed, for example, in the performance profile, Windows forces CPU power to always stay at max power, which isn’t necessary at all (more on it later). If you move one of the monitors around and do a PrtScn screenshot of the whole desktop you'll see what I mean in the result.Windows offers 3 preset power profiles that you can switch based on whether you want better performance or power saving. Your compiled image may need to have blank areas to make things line up right on all the monitors. Note: Remember to cope with monitors that aren't right next to each other or aren't aligned with each other. (It calls it once for each monitor.) I am not a Python developer so I'm not sure how you can call such a function from Python.Ī quick Google for "Python EnumWindows" (EnumWindows being a commonly-used API which returns results in the same way) finds people talking about that, and using a Lambda function for the callback, so it looks like it's possible but I'll leave it to someone who knows more about Python. That API returns its results via a callback function that you have to provide.

Then call SystemParameterInfo(SPI_SETDESKTOPWALLPAPER.) as you do already.īy the way, the code I'm looking at, which uses IActiveDesktop and falls back on the registry if that fails, passes SPIF_UPDATEINIFILE | SPIF_SENDCHANGE as the last argument to SystemParameterInfo you're currently passing 0 which could be wrong.ĮnumDisplayMonitors is the Win32 API for getting details on the monitors, including their screen sizes and positions relative to each other.

Under HKEY_CURRENT_USER\Control Panel\Desktop set: This isn't as nice, but works well enough. (As I'm not a Python dev, I'm not sure exactly how you access the COM object, sorry.)ī) Via the registry. You create an IActiveDesktop / CLSID_ActiveDesktop COM object and then call SetWallpaper, SetWallpaperOptions and finally Appl圜hanges.

This is nicest as on Win7 the new wallpaper will fade in.

After joining the images together into a big image, you have to set the wallpaper mode to tiled to make it so the image spans the desktop (otherwise it will restart on each monitor).Ī) Using IActiveDesktop (which does not require Active Desktop to be used, don't worry).
