Capture card for 4K30 recording

The ETECH GC551G2 Live Gamer Extreme 3 is a new external video capturing device built for gamers and content creators who want to record gameplay at 4K30. It accepts HDMI input from consoles such as PS5, Xbox Series X/S, Switch and Mini NES and connects to a PC or Mac via USB Type-C. The package includes the capture card, a USB Type-C to Type-A cable, an HDMI 2.0 cable and a quick start guide. No additional drivers are required for basic operation.

Sustained capture and pass-through behaviour

During long recording sessions the card maintains ultra-low latency on the pass-through signal, so gameplay on the connected display stays responsive while footage is written to the host system. It can capture at 4K30 and simultaneously pass through high refresh rates up to 1080p240. Variable refresh rate pass-through is supported at 1440p120 and 1080p120, keeping adaptive sync active on the monitor. HDR pass-through at 4K60 is also available for compatible displays.

Installation and common pitfalls

Setup is plug and play: connect the HDMI source to the input, the display to the output, and the USB cable to the computer, then launch streaming software such as RECentral, OBS or Twitch Studio. The most frequent issue is forgetting to enable VRR or HDR in the console and monitor settings, which leaves those features inactive on the pass-through. Another common mistake is using a USB 2.0 port, which cannot sustain the bandwidth needed for 4K capture.

Questions about this item

Does the GC551G2 get hot or draw much power when I leave it capturing 4K30 all day?

The Extreme 3 runs on USB power with no fan, so heat and draw stay low even during long 4K30 sessions.

What cables or ports must my PC already have for the GC551G2 to work?

You need a free USB Type-A port; the box includes a USB Type-C to Type-A cable and an HDMI 2.0 cable.

Will my older 1080p60 monitor still work through the GC551G2 pass-through?

Yes, the card passes 1080p up to 240 Hz and VRR at 1080p120, so a 1080p60 display works without changes.
