Usually this error is caused by having the display where the system window is created connected to a built-in video card different than the GPU where the rift is connected. 

Both your monitors and the rift need to be connected to your most powerful GPU. It's best to have no devices connected to any built-in video cards / ports, or ideally disable the built-in video card in the BIOS or windows device manager.
