Key Features:
A smart projector for a smart home
Take control of your home theater with voice commands. With the Alexa smart home and custom skills or Google Actions, control your 4K UHD 2,400 lumen Optoma UHD51A projector with intuitive voice control and easy integration using Amazon Echo and Google Home devices.
Use voice commands to power the projector on and off, change volume, change input source and control the USB media player. Additionally, the UHD51A utilizes the latest Texas Instruments 4K UHD DLP chipset capable of displaying 8.3-million simultaneous distinct pixels at screen sizes 140 inches and higher.
A pair of HDMI 2.0 inputs with HDCP 2.2 support, HDR compatibility and wide color gamut ensure 4K device compatibility, rich lifelike color and contrast for immersive experiences. A 1.3x optical zoom and 15% vertical lens shift provide installation flexibility.
Alexa Smart Home and Custom Skills
Alexa smart home and custom skills enable projector control via Amazon Alexa. Supported control functions include power on/off, volume level, input selection, USB media player playback and image mode changes.
Google Assistant Compatible
Google Voice Action compatibility provides projector control via Google Assistant. Supported control functions include power on/off, volume level, input selection, USB media player playback and more.
DLP Technology
DLP® (Digital Light Processing) is a proprietary technology from Texas Instruments that offers digital projection with higher contrast, faster response time, good pixel structure and virtually no color degradation.
Full 3D
Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. Optoma 3D glasses required.
Dynamic Black Technology
This feature gives more depth to your image by smoothly adjusting the lamp output to create a stunning high contrast ratio. Bright scenes appear crisp and clear, while dark scenes remain detailed with deep blacks and exceptional light and shade detail.
PureMotion
Using sophisticated frame-interpolation technology, advanced motion control processing eliminates motion blurring or image judder, even in high-speed action sequences. PureMotion works in both 2D and 3D and is optimized for 1080p24.
UltraDetail
This technology ensures all the information contained in an image is accurately reproduced on the screen to give a stunning crystal clear, pin-sharp picture. Complex algorithms detect each frame and improve image sharpness before the frame is projected.
PureColor
This mode allows the projector to reproduce more detailed shades of color for vibrant, natural-looking images. Colors are more saturated and more accurate.
Vertical Lens Shift
Vertical lens shift simplifies installations by shifting the image up and down without image distorsion to provide a wider range of projector placement possibilities, making it easier to position the projector in a room.
HDR
High dynamic range (HDR) technology delivers brighter whites and deeper black levels. Optoma HDR accepts HDR10 signals with four selectable picture modes: Normal, Bright, Detail, Film
DCI-P3
Color the way it is meant to be seen – rich, colorful and cinematic pictures and games via DCI-P3 wide color gamut coverage.
BT.2020
HDR signals are mapped using REC.2020 tone mapping and provides coverage for REC.709, DCI-P3 and a wide coverage color gamut.
PC-Free USB 4K UHD HDR Media Player
Integrated 4K UHD HDR USB Media Player provides playback of 1080p and 4K UHD HDR video, audio files and images along with support for Office Documents and PDF Files.
