Eye Tracking - HTC VIVE Pro Eye User Manual

Can I use a laptop with VIVE Pro Eye?
As long as your laptop meets the system requirements, you can use it with VIVE Pro Eye.
If your laptop does not have a DisplayPort port but has a Mini DisplayPort port instead,
you can purchase a Mini DisplayPort-to-Mini DisplayPort 1.2 or newer cable, and then
connect it to the link box and to your laptop. Make sure that the cable you purchase
supports Ultra High Definition (UHD) 4K @ 60Hz or higher.
This workaround does not guarantee compatibility. Contact your computer or accessory
manufacturer if you have questions.
