Do I really need a 4K webcam, or is 1080p enough?

Across the reviewers we read, the practical consensus is that for video calls and most streaming, 1080p is plenty because services like Zoom and Teams heavily compress the feed anyway. Several community threads note that lighting matters more than raw resolution. 4K becomes worthwhile mainly for content creators who crop, zoom, or want digital pan-tilt-zoom headroom from a fixed camera.
