Oculus Rift S and Valve Index don’t jive with HDMI-only laptops

The original Oculus Rift used HDMI but its replacement, Oculus Rift S, uses DisplayPort instead. It also includes a Mini DisplayPort adapter in the box. Valve’s Index VR headset also uses DisplayPort, and while it doesn’t include a Mini DisplayPort adapter, you can find them on Amazon for around $10 if needed.

If you have a desktop PC this shouldn’t be a problem as most graphics cards have multiple DisplayPort outputs. If you have a VR-ready laptop with DisplayPort or Mini DisplayPort you should also be fine. Note that many laptops are not VR-ready.
