Three years after the launch of PlayStation 5 and Xbox Series X we finally have a proper HDMI 2.1 USB-C capture card in our hands. The $300 AVerMedia Live Gamer Ultra 2.1 GC553G2 Capture Box, as it's called in its entirety, is without a doubt the most important capture card to launch in 2023 and recent years. While it's not the first such product to see the light of day, it's certainly the most ambitious one in terms of capture and passthrough capabilities. The "Capture Box" suffix hints at this being an external USB capture device, differentiating it from AVerMedia's other upcoming HDMI 2.1 product, the Live Gamer 4K 2.1 (GC575), which is a PCI Express card, so a "card" in the true sense of the word.
Let's not get tangled up in the naming schemes though, as there's much to unwrap. The AVerMedia Live Gamer Ultra 2.1 GC553G2 Capture Box, which I'll refer to as the AVerMedia Live Gamer Ultra 2.1 for the remainder of this review, enables live streamers and content creators to capture 4K video at 60 FPS while simultaneously gaming on their monitor in 4K at up to 144 Hz (120 Hz for console 4K gaming is natively supported as well), with full VRR and HDR support. The device also has a 3.5 mm combined audio input and output, as well as a 3.5 mm audio passthrough, which you can connect to your controller, to hear your game sound, and to make yourself audible both to your squad and your audience. All this works through a USB-C interface; AVerMedia finally puts 10 Gbps USB Type-C ports, lined up on the backs of modern motherboards, to good use.
