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.

Amazing Color

Our projectors are capable of reproducing the Rec.709 color gamut, the international HDTV standard to guarantee accurate reproduction of cinematic color exactly as the director intended.

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.


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.

ISF Modes

This feature allows you to save your calibrated day and night mode settings for the ideal viewing experience.

Long Lamp Life

Save time and money with long lamp life. Reducing the amount of lamp changes results in less downtime and lower maintenance costs for lower total cost of ownership.

Vertical Lens Shift

Vertical lens shift simplifies installations by shifting the image up and down without image distortion to provide a wider range of projector placement possibilities, making it easier to position the projector in a room.

Enhanced Color Wheel

An RGBRGB color wheel increases the color ratio for richer, vivid and cinematic image.


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, and Film.


Color the way it is meant to be seen – rich, colorful and cinematic pictures and games via DCI-P3 wide color gamut coverage.


HDR signals are mapped using REC.2020 tone mapping and provides coverage for REC.709, DCI-P3 and a wide coverage color gamut.

3D Ready

Optoma 3D Ready projectors can output video and images at an astonishing rate of 120Hz, allowing you to show full-screen, full-color, stereoscopic 3D. 3D glasses are needed and are sold separately. Refer to user manual for details.

UHD50 – DigitalTends Review

May 31, 2018

Everybody wants the visual experience of a movie theater without leaving the comfort of home, but historically that’s been difficult – or, at least, expensive. While there’s nothing like dimming the lights, popping a cold one, and watching your favorite film, tv series, or sports team in massive, 100-plus-inch glory, finding a projector of suitable quality at a price that didn’t put a major dent in the new car fund has been an insurmountable stumbling block.

Sure the Optoma UHD60 projector looks slightly sharper with 4K, but superb contrast is its real strength.


Optoma HD142X


The Optoma HD142X projector spits out wall-filling swaths of full-HD resolution for less than the cost of a decent 50-inch TV.

    3 out of 5 First projector

    This is my first projector and it was great till it suddenly shut down within 3 months of usage. Optoma were however prompt in fixing the projector and shipping back. HD and 4K is awesome. It does generate a lot of heat though. Being PC 3D ready, I am hoping to get 3D working someday.

    5 out of 5 UHD50........Brilliant!!!

    I was skeptical about making the jump to 4K home theater projection but after researching this unit sounded perfect for my home theater needs. I got it set up perfectly and the image quality on this thing is astounding. I’ve watch several 4K titles and my jaw drops every time. It was easy to set up and align with my screen very nice projector.

    5 out of 5 Best size, price and quality

    I’ve owned and used Optoma UHD60 and Benq ht2550 as other 4k dlp projectors earlier. While UHD60 had an amazing quality, had so much issues and compatibility problems with ht2550. But the UHD60 was pretty bulky and heavy for the average home user. So uhd50 is the best thing in between. Quality is still almost as good as uhd60, which perfetly sharp, crystal clear, a real 4k, which works seamlessly with Chromecast, xbox one x, all 4k hdr devices. On the other side, it’s half the size and weight of uhd60 and input lag is much less. For the this projector is a winner.

    5 out of 5 If you are ready to upgrade your projector to 4k - This is a great choice!

    I knew that the picture would be improved moving from 1080p to 4k, but I am blown away with the detail that the UHD50 displays on my 120″ screen. Another unexpected feature was just how quiet the fan is. I am very pleased with my purchase, an amazing value for under $1500.00.

    5 out of 5 I love my first projector

    This is my first projector and I absolutely love it. Set up was very easy, thanks to features like lens shift, zoom, and keystone correction. I currently have it set up with an Apple TV 4th generation and the picture looks great. I am now thinking about upgrading to the Apple TV 4K so I can fully take advantage of the UHD50’s capabilities.

    5 out of 5 Awesome Projector!

    This projector is definitely an amazingly capable 4K HDR projector at a fraction of the price. I have it set up at 14 to a 135 inch screen and it is picture perfect. It also does gaming like a champ. I am thrilled to have all of this punch at such a value price when compared to other units This projector is truly exceptional so far. I highly recommend this one!

    5 out of 5 Better than expected, great price point

    I’ve spent the last six months reviewing 4K reasonable priced projectors with the UHD65 and UHD60 be at the top of my list to purchase, except for their price point. When I saw the UHD50 released, the specs, features and price point where right in line with my home theater needs. The one major concern I had was how smooth fast motion video for hockey would be, hence why the UHD65 was tops on my list. My fear was completely unfounded and very impressed with the seamless picture quality. Upgrading from a 2000 lumens 1080i projector with brightness and greatly improved contrast, even without the HDR simulation is well worth the money. The HDR sim on makes it even better. Love the simple menu system for changing settings including the remote control for the most common settings. I certainly recommend the product as you can’t beat having a 4K experience on the big screen and makes me look forward to having an outdoor movie night in the big yard this summer.

    5 out of 5 True 4K HDR at a Bargain Price

    I thought I would have to wait a couple of years to get a true 4k HDR relatively shorter throw projector, so I was thrilled to see Optoma release the UHD50. It throws a crystal clear 4k image onto my 1.1 gain white screen from 12′ for 132″ of viewing pleasure! YouTube 4k HDR and PS4 Pro images look incredible. My setup rivals those costing 10 to 20 times a much just a year ago. Would definitely recommended this projector to anyone looking to take the leap from 1080p.
