Final Verdict

Both run BenQ’s 4LED 4K gaming platform with the same low-lag, high-refresh modes and Android TV streaming, so the choice comes down to room and budget. The X500i is the short-throw: a big image from close range, ideal for bedrooms and apartments where the projector sits near the screen. The X3100i is the brighter flagship with more headroom for large screens and some ambient light. Small room or tabletop setup: X500i. Dedicated gaming den with a 120-inch ambition: X3100i.
