Q: Can I record 4K video with the VC-321? A: No. While the card passes through 4K video to your monitor, the capture resolution is limited to 1080p / 60fps. For 4K recording, consider a dedicated 4K capture card. Q: Does it work with USB 2.0 ports? A: Physically yes, but USB 2.0 bandwidth may cause dropped frames or instability at 1080p60. The manufacturer strongly recommends using a USB 3.0 port. Q: How much latency should I expect? A: The HDMI pass-through output is near-zero latency, so you can play games on your monitor without noticeable delay. The PC preview window will have a small delay (tens of milliseconds), which is normal and acceptable for streaming.
