Simply plug in your Live Gamer EXTREME 3 along with HDMI and it is ready to stream. It is a simple and easy to use capture solution. You can extend its functions by using AVerMedia Streaming Center.
4Kp30 Uncompressed Capture
Capture your gameplay in high detail with the support of up to 4K30p on a 4K 60Hz HDR Monitor. If fast is your pace, switch to QHD and play at up to 120Hz while recording at FHD60p. Thanks to the uncompressed capture capabilities, your gameplay will be captured exactly the way it is meant to be.
Variable Refresh-Rate
The brand-new Live Gamer EXTREME 3 supports VRR to give you tear-free and stutter-free gameplay with supported devices.
Ultra-Low Latency
With nearly zero latency on the pass-through signal, and ultra low latency through to the streaming signal, the Live Gamer Extreme 3 makes sure both your gameplay and stream are smooth and lag-free.
Multi Stream
Level up your stream and stream to Twitch, YouTube, Facebook and many other platforms simultaneously with AVerMedia Streaming Center.
Audio Line In & Line Out
Thanks to the built in Line-In and Line-Out connection, it is a breeze to re-route your audio into a mixer or mix in different audio outputs into the stream source.
