Specification note: Each HDMI input supports video up to 4K30; the supplied documentation does not explicitly guarantee simultaneous four-channel capture at full 4K30. Available channel count, resolution, and frame rate during multi-channel operation depend on the sources, host platform, PCIe slot, driver, and application software. Video loop-through is not supported. HDCP-content compatibility depends on the complete system, and protected or encrypted content may not be capturable.
