Before you choose

Elgato Cam Link 4K

The catch: There is no HDMI display output. Identify the unit’s revision before planning 4K frame rates, then test clean HDMI and continuous camera power; use a passthrough card for a separate gaming display.

You need:

  • A USB 3 port (5 Gbps), straight on the computer
  • An HDMI cable from your console or camera

Check first:

  • HDCP turned off on the source

Elgato Game Capture 4K S

The catch: Select a listed capture mode and a separate listed display mode. If HDR or high refresh is essential, match both exact modes before choosing this card.

You need:

  • A USB 3 port (5 Gbps), straight on the computer
  • A second HDMI cable, from the card to your screen

Check first:

  • A USB-C port on your computer
  • HDCP turned off on the source

What else each needs

Elgato Cam Link 4K

Cam Link 4K
A USB 3 port (5 Gbps), straight on the computer
A free USB port
An HDMI cable from your console or camera
HDCP turned off on the source
Camera Hub optional; UVC-compatible application
  • You need: A USB 3 port (5 Gbps), straight on the computer. A USB 2 port is too slow for it. The maker asks for a direct port rather than a hub. USB-C is a plug shape, not a speed, so check the port itself.
  • Check first: A free USB port. The device plugs in directly; the short extension in the box only moves it away from the port.
  • You need: An HDMI cable from your console or camera. No HDMI cable is listed in the box.
  • Check first: HDCP turned off on the source. It captures unencrypted HDMI only. Consoles have their own HDCP setting; protected films and streaming apps cannot be captured.
  • Optional: Camera Hub optional; UVC-compatible application. The maker’s app adds settings; the device works without it.

Elgato Game Capture 4K S

Game Capture 4K S
A USB 3 port (5 Gbps), straight on the computer
A USB-C port on your computer
A second HDMI cable, from the card to your screen
HDCP turned off on the source
  • You need: A USB 3 port (5 Gbps), straight on the computer. A USB 2 port is too slow for it. The maker asks for a direct port rather than a hub. USB-C is a plug shape, not a speed, so check the port itself.
  • Check first: A USB-C port on your computer. The cable in the box has USB-C at both ends. If your computer only has USB-A ports, you need a USB-C to USB-A cable rated for the same speed.
  • You need: A second HDMI cable, from the card to your screen. Passthrough sends the game on to your TV or monitor with no delay, and that needs its own cable.
  • Check first: HDCP turned off on the source. It captures unencrypted HDMI only. Consoles have their own HDCP setting; protected films and streaming apps cannot be captured.
