Are you wondering if the Valve Index requires a DisplayPort connection? The answer is yes, it does.

What is the Valve Index?

The Valve Index is a virtual reality (VR) headset developed and produced by Valve Corporation, a well-known company in the gaming industry. It was released in June 2019 as a successor to the HTC Vive, another popular VR headset.

Why does the Valve Index require DisplayPort?

The Valve Index uses DisplayPort 1.2 or newer to connect to your computer. This is because DisplayPort provides better bandwidth and refresh rates compared to other video interfaces like HDMI.


Bandwidth is the amount of data that can be transmitted through a cable per second. The higher the bandwidth, the more data can be transmitted.

This is important for VR headsets because they need to display two high-resolution images simultaneously – one for each eye. DisplayPort provides up to 32.4 Gbps of bandwidth, which is enough for high-quality VR experiences.

Refresh Rates

Refresh rate refers to how many times per second an image on the screen updates. Higher refresh rates provide smoother motion and reduce motion sickness in VR experiences. The Valve Index has a maximum refresh rate of 144 Hz, which requires DisplayPort to achieve.

What if your computer doesn’t have a DisplayPort?

If your computer doesn’t have a DisplayPort, you may still be able to use the Valve Index with an adapter. However, not all adapters work with VR headsets due to their high bandwidth requirements. It’s recommended that you use an adapter that supports at least DisplayPort 1.2 and has been tested with VR headsets.

  • HDMI Adapter: Some HDMI adapters may work with the Valve Index, but they may not support its full capabilities like high refresh rates.
  • USB-C Adapter: If your computer has a USB-C port, you may be able to use a USB-C to DisplayPort adapter. Again, make sure it supports DisplayPort 1.


In summary, the Valve Index requires a DisplayPort connection due to its high bandwidth and refresh rate requirements. If your computer doesn’t have a DisplayPort, you may be able to use an adapter, but make sure it meets the necessary specifications and has been tested with VR headsets.
