Pros & Cons
👍 Pros

- Features low latency of 8.3ms at 1080p/120Hz, providing a highly responsive gaming experience.
- Includes integrated 5-watt speaker by treVolo with an equalizer, offering excellent audio quality without external speakers.
- Comes with Game Mode and Game Sound Mode to fine-tune audio and images, enhancing the gaming immersion.
- Equipped with LumiExpert technology designed to reduce eye strain during extended gaming sessions.
- Offers broad compatibility with major video game consoles such as Sony PS4, Nintendo Switch, and Xbox One X, as well as Google Stadia.
- Supports connections to media players and 4K UHD HDMI dongles like Amazon Fire TV, Google Chromecast, or Apple TV for streaming content.
- Backed by an industry-leading 3-year warranty from BenQ, providing greater peace of mind compared to competitors' shorter warranties.
👎 Cons
- As a renewed product, it might not come with the same pristine cosmetic condition as a new item, though functionality should be restored.
- While it is 4K compatible, its native resolution is 1080p, meaning 4K content will be downscaled.
- The 5-watt integrated speaker, while good, may not provide the immersive audio experience of a dedicated home theater sound system.
- Lumen output of 3500 ANSI might be too bright for very dark home theater environments, potentially washing out deep blacks.
- Focuses heavily on gaming features, which might mean some advanced home theater picture processing specific to movies is less emphasized.
- The projector requires 100-inch images from 8.2 feet away, which dictates room setup and might not suit smaller spaces.
