Third-party reviews

What customers like about Optoma GT5600

  • Ultra-short-throw design allows for a 100-inch image from just inches away
  • High brightness (3,600 lumens) suitable for environments with some ambient light
  • Excellent picture clarity and sharpness for both movies and gaming
  • Fast 16ms input lag provides a smooth gaming experience
  • Strong 16W built-in speaker and solid overall build quality
  • Supports 3D content for a home cinema experience

What customers don't like about Optoma GT5600

  • Noticeable fan noise or high-pitched 'whine' from the color wheel during quiet scenes
  • Significant heat output that can noticeably warm up smaller rooms
  • Requires a perfectly flat surface or a fixed frame screen to avoid image distortion/waviness
  • Slow startup and restart times, common with lamp-based units
  • Lacks built-in modern connectivity like Bluetooth, Wi-Fi, or AirPlay
  • Difficult to align and not recommended for ceiling mounting due to the sharp projection angle

Verdict

The Optoma GT5600 is a high-performance 1080p DLP ultra-short-throw projector designed for gaming and home cinema, capable of projecting a 100-inch image from just inches away due to its 0.25:1 throw ratio. It features a bright 3,600 ANSI lumens output and a 20,000:1 contrast ratio, ensuring sharp visuals even in ambient lighting, complemented by a powerful built-in 16W speaker and a lamp life reaching up to 15,000 hours in Dynamic mode. Key pros include its easy setup with auto-keystone and four-corner correction, Full 3D support, and PC-free media playback via USB. However, potential drawbacks include a relatively high input lag of 49ms for competitive gaming, noticeable fan noise in brighter modes, and a lack of native HDR support.
