100 inch image with the projector just 30cm away

The HD31UST gives you a big screen without needing a big room! This ultra-short throw projector is designed to work at very close range to a wall or screen. Simply place on a bracket, shelf or sideboard in front of the wall and you’ve got instant big screen entertainment – whatever the size of room.

Super-bright for ‘lights on’ viewing
Thanks to a class-leading brightness figure of 3400 ANSI Lumens, the HD31UST is flexible enough for all room environments. Even during daylight conditions with curtains or blinds open, the Optoma produces a bright, natural picture. Now you can enjoy big screen entertainment at any time of the day, without having to keep the sun out.

Make the most of movies, TV and gaming with 1080p resolution
Using sophisticated DLP technology, the Optoma HD31UST gives crystal clear clarity, sharply defined images and true, natural colour. Even at larger screen sizes, the detail is astounding. Thanks to 1080p Full HD resolution you can make the most of high definition video sources, making it the perfect match for your Blu-ray player or Full HD gaming device.

Brilliant colour
Colour precision, resolution, frame rate and display specifications are all guaranteed by meeting one of the highest HD video standards seen in professional-grade home cinema today: Rec. 709. Instigated by the ITU (International Telecommunication Union), Rec.709 approval means a true cinema-like appearance.

HDMI with USB charge for easy smart entertainment
With twin HDMI sockets, the HD31UST is well equipped to handle your digital sources. The HDMI interface is perfect for hooking up a smart entertainment device, such as Apple TV, Amazon Fire Stick or Google Chromecast. With a USB charge socket as standard, charging the dongle is also possible, giving easy playback of your favourite smart content.

Make watching on the big screen easy, with the flexible Optoma HD31UST.
