Everytime I use Lenovo SplitScreen, my Wi-Fi drops to 5 kilobits per second, even if I don't have my monitor connected. It's not the monitor, so any mac users reading this should rule this out, it is the hardware in the laptop I'm betting, because I got my external monitor hooked up without sending a signal to it, and my wifi works just fine.
So if someone can try this, press Fn+F3, and use Extend, or really any of them except "Computer only", and tell me if your wifi still works or not.
