Stunning HDR Performance

  • High Dynamic Range is one of the most important features that greatly improve the viewing experience for 4K UHD displays.
  • The UHD51 manages HDR metadata incredibly well, retaining details in both extremes of light and dark on the same image, so as to bring you exactly what your eyes perceive in real-life scenarios.
  • A natural balance between the brightest and the darkest areas ensures no details are lost, making the projected HDR images second to none.


  • Professionally engineered for users, UHD51 has a very quiet operation at 25 dB. Enjoy TV shows, movies, games with peace of mind.

Pure Motion

  • PureMotion is a sophisticated frame interpolation processing technology that compensates for videos filmed in 24fps to remove motion blur.
  • The processing generates transitional frames between existing ones to reduce motion judder, giving you a smooth viewing experience during action-packed, fast-moving scenes.

Full 3D

  • Experience Full HD 3D projection with the UHD51 straight from your Blu-ray source. Optoma UHD51 is fully compatible with the DLP-Link 3D solution allowing you to enjoy 3D cinematic projection from your existing Blu-ray disc collection.
  • For the best Blu-ray 3D performance, 1920×1080 resolution is recommended. Please note that there is no 4K 3D standard available.

Alignment Free

  • DLP 1-chip systems are inherently mechanically perfectly aligned.
  • For 3 panel systems, any panel misalignment can cause color or image artifacts and lost resolution.
  • 4K pixels are typically smaller than 1080p pixels, making alignment in 3 panel systems even more challenging.

Flexible Installation

  • The UHD51 is designed exclusively with theater rooms or living spaces in mind.
  • With 1.3x zoom & a perfect throw ratio (1.2-1.56), you can install your projector for a 120? screen at only 3.21m distance,
  • only repositioning your image using the Vertical Lens Shift if needed.
