AVerMedia today announced a couple of new capture cards that it claims are the first to enable 4K HDR game streaming, though that's not the only standout feature. One of the cards is an external capture box that is said to play nice with laptops.

That would be the Live Gamer Ultra, which features full 4K HDR passthrough and onboard video processing. It doesn't require any special drivers—just plug it in, install the software, and capture your HDR gameplay. It supports recording 4K HDR streams at 30 frames per second, and 60 frames per second at 1440p and 1080p. If you disable HDR, it can record 1080p gameplay at 120 fps.
