Designed for all types of entertainment, the Optoma UHD55 is a flexible projector that delivers. Big time.

Brilliant all-rounder
With its sharp image, high brightness, low input lag and high spec, the Optoma UHD55 is the perfect all-rounder. Crisp and detailed with movies, super-responsive with gaming, yet bright enough for ‘lights on’ TV, the UHD55 excels with all entertainment.

‘Lights on’ viewing
Designed with regular living rooms in mind, the UHD55 produces a picture brightness figure of 3600 lumens. Bright enough for a clear, detailed picture in rooms that have the curtains or blinds open and the lights on, this new generation projector is free from the compromises of old.

Rich detail, with HDR10 and HLG
Compatible with HDR10 and HLG formats, the UHD55 gets the best from your movies, games and TV. HDR enhances the brightest and darkest sections of scenes – letting you see detail in what was previously a solid block of colour. It also makes the rest of the colour spectrum appear more natural, giving an even greater sense of ‘being there’.

UHD 4K resolution for the crispest definition
Maximising HDR’s full potential, the UHD55 utilises UHD 4K resolution. Projecting at this resolution gives detail and realism that's impossible to achieve with conventional Full HD. UHD 4K resolution is four times greater than the more conventional 1920 x 1080 projectors and it's a difference that’s all the more obvious on a large projection screen. Astonishing detail and the sharpest definition make this the perfect projector for UHD 4K viewing.

True colour
The UHD55 is capable of reproducing the Rec.709 colour gamut, the international HDTV standard to guarantee accurate reproduction of cinematic colour - exactly as the director intended. Enjoy watching films and TV shows and playing games with stunning colours in any environment.

On your side for the fastest gaming
Just like when watching movies, a big screen delivers big thrills with gaming, too. Game Mode takes this further by optimising the projector’s contrast and producing vivid detail and maximum contrast – perfect for spotting the danger lurking in the shadows. With input lag reduced to as little as 16ms (at 4K/60Hz), you can be assured lightning-fast response times. 3x3 Warping delivers geometric correction for lifelike imagery. Game at FHD (1080p) resolution and enjoy 240Hz, super-smooth motion and an explosive response of just 4ms.

Lens Shift for ease of installation
Being able to 'shift' the lens vertically (+ 10 degrees) makes installations much easier. Lens shift gives you the perfect image, even after installation, without having to sacrifice image quality. In addition, 1.3x zoom lets you size the image to your exact requirements.

At your command – voice control
If you own an Amazon Alexa or Google Assistant device, then controlling this projector is just a voice command away. Ask Alexa or Google to turn the projector on/off, adjust the volume, change the input and more.

Smart apps
Using the built-in App store Marketplace, you can access a wide range of entertainment apps, giving you effortless control from your smartphone or tablet. Netflix, YouTube and Spotify are just three of the most popular apps that are ready to go. Note – Google Play services not supported.

Flexible connectivity, including twin HDMI sockets
Featuring twin HDMI sockets, you can connect a Blu-ray player or games console and video streamer. For older sources, the UHD55 also comes with a VGA input – perfect for laptops and PCs. Three USBs (one is service and power only) give ample media connection points. Multi-room connectivity is enhanced by RJ-45 and RS232 interfaces, plus there’s a 12v output for syncing with an electric screen. Audio is outputted via digital optical or analogue 3.5mm sockets.

Power your smart TV device by USB
Another great feature is the handy USB power output. This provides a 5V/1.5A power output that’s ideal for powering many types of Smart TV sticks, such as those from Roku and Google.

Enjoy the unbeatable thrill of a big screen, with whatever you watch, with the Optoma UHD55.
