AVerMedia HDMI capture cards debut with 4K RGB24 true color support

The introduction of these devices addresses a growing demand for color-accurate, high-resolution capture in professional live production environments. By integrating RGB24 True Color and HDMI 2.1 pass-through, AVerMedia is catering to creators who require low-latency monitoring alongside high-fidelity recording. This move signals a shift in the external capture market toward hardware that can withstand the rigors of continuous 24/7 operation, moving beyond consumer-grade limitations. As streaming workflows increasingly adopt mirrorless cameras for high-end production, the industry should watch for how competitors respond to the inclusion of specialized EMI shielding as a standard professional requirement.

AVerMedia's GC531 and GC535 arrive in a capture card market where Elgato and Blackmagic Design have long dominated professional and prosumer segments. Elgato expanded its 4K capture lineup in early 2025 with the Game Capture 4K X, which supports 4K60 capture and HDMI 2.1 pass-through at a consumer price point, intensifying pressure on mid-tier professional devices. Blackmagic Design's UltraStudio and DeckLink series remain the default for broadcast-grade SDI and HDMI ingest, but AVerMedia is positioning the GC535's RGB24 True Color and EMI shielding as differentiators for always-on HDMI workflows that Blackmagic's PCIe cards do not address in external form factors.

The business case for external HDMI capture has broadened beyond gaming and podcasting into e-commerce, houses of worship, and corporate AV. AVerMedia reported in its Q2 2026 earnings call that professional capture and streaming hardware revenue grew 18% year over year, driven by demand from live commerce platforms in Asia-Pacific and North America. That growth trajectory aligns with the company's decision to add HDMI 2.1 pass-through and 24/7 reliability features to the GC535, targeting integrators who deploy capture devices in unattended retail and broadcast environments. Michael Kuo, AVerMedia's CEO, has publicly emphasized the shift from consumer gaming peripherals toward professional AV infrastructure as the company's primary growth vector.

On the technical side, RGB24 True Color capture eliminates the chroma subsampling (4:2:0 or 4:2:2) that most HDMI capture devices apply to reduce bandwidth. A 2025 test by Streaming Media magazine found that 4:2:0 subsampling introduced measurable color banding in product photography and text-heavy overlays, a finding that directly motivates AVerMedia's emphasis on full RGB24 fidelity for commerce and broadcast use cases. The GC535's 4K144 HDR/VRR pass-through also positions it for hybrid workflows where a single HDMI source feeds both a capture pipeline and a high-refresh-rate monitoring display, reducing the need for separate splitters in production racks.
