So Minecraft worked fine until I got another monitor. I hooked up the second monitor, that worked, then opened the Minecraft launcher from my taskbar. I wasn't seeing anything, and that's because this was happening: https://gyazo.com/6ff22245ff3e0f54954d05a9444806fd.
You can see in the bottom right corner that the Minecraft APPEARS to be opening, but it isn't showing up, either on the first or second monitor. I have absolutely no idea how to fix this. Help?
