How Can I Fix this problem?

Hi, we just bought a brand new HTC vive than install it to our PC, which has six core Xeon CPU, GTX 980 ti as well as 32GB ram. But when we open our demo in the UE4 editor, the display has strong distortion, so I hope anyone can help us, thank you.

Have you tried updating the headset firmware? This exact thing happened to me once and updating the firmware fixed it.
