## What reviewers say

**AVerMedia Live Gamer 4K 2.1 (GC575)** — Only one whitelisted tester (TechPowerUp) hands-on reviewed the GC575. It measured sub-0.5 ms HDMI passthrough latency at 1440p144 and called overall capture performance outstanding, praising lag-free HDMI 2.1 passthrough up to 4K144 with HDR and VRR, but flagged that the PCIe interface adds no capture-resolution gain (no 4K120/144 capture) over the external USB-C model and that ultrawide passthrough is capped at 120 Hz.
