True 4K UHD Display

The Optoma UHD51 delivers accurate, razor sharp, high quality images by leveraging the DLP 4K UHD chip and XPR technology. Capitalising on the fast switching speed of the DLP chip and advanced image processing, over 8 million pixels are delivered to the screen.

Sharp Details – You won’t miss a thing!

The lens’ optical grade plays a crucial part in projector image quality especially for 4K UHD projectors where the pixels are so fine. Thanks to the newly designed high resolution lens, the UHD51 is optically capable of resolving and showing all the details the 4K UHD content has to offer. You won’t miss anything from your favourite sports game, blockbuster movie or TV series!

Exceptional Colours

The UHD51 offers true to life, stunning colours that meet the Consumer Technology Association standards for Wide Colour Gamut display. Being able to receive and decode ITU-R recommended BT.2020 input signals and remap appropriately for display, you can expect nothing but the best cinematic colours.


PureMotion is a sophisticated frame interpolation processing technology that compensates for videos filmed in 24fps to remove motion blur. The processing generates transitional frames in 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.

Stunning HDR Performance

High Dynamic Range is one of the most important features that greatly improves 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.

What is HDR?

HDR stands for High Dynamic Range. In a nutshell, HDR is the ability to display a wider and richer range of colours, much brighter whites, and much deeper, darker blacks in the encoded contents. HDR removes the limitations of both contrast and dynamic range by providing additional information (metadata) about brightness and colour across a “wider range”.

Alignment Free

DLP 1-chip systems are inherently mechanically perfectly aligned. For 3 panel systems, any panel misalignment can cause colour or image artefacts 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 specifically with theatre 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.
