What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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. (1 sourced review, 1 lab-tested.)
Praised: Outstanding, artifact-free capture quality with vibrant colors; Lag-free HDMI 2.1 passthrough up to 4K144 with HDR and VRR; Seamless OBS integration.
Flagged: No 4K120 or 4K144 capture despite the extra PCIe bandwidth; Ultrawide (3440x1440) passthrough limited to 120 Hz.
