Before you choose

AVerMedia Live Gamer ULTRA 2.1 GC553G2

The catch: It needs a USB-C port rated USB 3.2 Gen 2 (10 Gbps) and an HDMI 2.1 display and console for its top passthrough modes. 4K144 capture is MJPEG on Windows in AVerMedia’s own software; macOS captures up to 4K60, without HDR.

You need:

  • A 10 Gbps USB port
  • A second HDMI cable, from the card to your screen
  • AVerMedia Streaming Center for 4K144 (Windows); Assist Central Pro

Check first:

  • A USB port that fits the cable

AVerMedia Live Gamer ULTRA S GC553Pro

The catch: Choose the capture mode for your Windows PC or Mac. The HDMI source must not be copy-protected (HDCP); a different cable won’t make protected video capturable.

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

What else each needs

AVerMedia Live Gamer ULTRA 2.1 GC553G2

Live Gamer ULTRA 2.1 GC553G2
A 10 Gbps USB port
A USB port that fits the cable
A second HDMI cable, from the card to your screen
AVerMedia Streaming Center for 4K144 (Windows); Assist Central Pro
  • You need: A 10 Gbps USB port. Its full modes need 10 Gbps.
  • Check first: A USB port that fits the cable. A USB-C cable is in the box; check its other end against your computer’s ports.
  • 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.
  • You need: AVerMedia Streaming Center for 4K144 (Windows); Assist Central Pro. The maker lists this software for the device to work as described.

AVerMedia Live Gamer ULTRA S GC553Pro

Live Gamer ULTRA S GC553Pro
A USB 3 port (5 Gbps), straight on the computer
A USB-A 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-A port on your computer. The cable in the box is USB-C to USB-A. If your computer only has USB-C ports, use a USB-C to USB-C cable instead.
  • 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.
