1080p ultra short throw home entertainment projector
Project a super-sized 100-inch image with the HD35UST placed less than 30cm away from a flat surface* or screen. Feel the action and experience every moment on the big screen for immersive live sports, TV shows, gaming and movies.

Convenient and easy to set up this compact high brightness projector is ideal for well-lit environments so sports fans can enjoy live action with family or friends with the lights on. Boasting Amazing colour technology, it delivers accurate true-to-life colour reproduction for movie lovers. It also has low input latency – perfect for games that rely on rapid reactions.

An integrated speaker provides powerful sound and two HDMI inputs enable connection to multiple devices such as set-top boxes, games consoles and HDMI dongles.

*30cm measured from the back of the projector. Like all Ultra short projectors; to get a perfect image requires a completely flat surface. As most walls are not entirely flat, to avoid slight distortion to the top of the picture, you may need to install a screen onto your projection surface for a perfect image. If this is not possible, we suggest that for non-flat walls you might be better to use a short throw projector which can throw a 100” image from just over 1m”.

Ultra Short Throw
With an ultra-short throw lens, you can project an impressive image greater than 100” from less than a metre away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease; perfect for interactive applications.

Lights on viewing
This all-round home entertainment projector combines high brightness and vivid colours for vibrant, true-to-life visuals in well-lit environments* – ideal for watching TV shows, sports and movies or gaming with family or friends any time of day.

*With no direct sunlight or lights directed on screen.

Full HD 1080p
1080p resolution gives you sharp and detailed images from HD content without downscaling or compression; perfect for watching Blu-ray movies, HD broadcasting and playing video games.

Amazing colour
Watch your movies, TV shows and play games with stunning colours in any environment. Optoma projectors provide reliable performance suitable for any content and environment. Our home projectors are capable of reproducing the Rec.709 colour gamut, the international HDTV standard to guarantee accurate reproduction of cinematic colour exactly as the director intended. Or more saturated colours for a punchy looking image, great for gaming and animated movies.

Full 3D
Optoma projectors can display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting and the latest generation games consoles.

Dual HDMI inputs
Play games, stream videos and share photos on the big screen in the comfort of your own home. With dual HDMI inputs, you can easily connect to your games console, set-top box, laptop, PC, Blu-ray player or media streamer with a single cable. You can even turn it into a smart projector by connecting an HDMI dongle like the Google Chromecast™, Amazon Fire TV, Apple TV™ or Roku® stick.

USB display
Connect your projector directly to a laptop and display the desktop using a USB cable. No need for a bulky VGA lead.

Four corner correction
Adjust the keystone in both the vertical and horizontal plane. You can individually warp each corner of the image to create a perfectly square image. Ideal for uneven walls or where projector placement is awkward and needs to be installed at an angle.

Integrated speaker
A powerful built-in speaker provides exceptional sound quality and an easy setup without the need for costly external speakers.
Use the USB-A port to power an HDMI dongle, such as Google Chromecast.
Auto power off
There may be instances when the projector is left running when not in use. To help save energy, the “auto power off” feature automatically turns off the projector after a set period of time if it is not being used

Quick resume
This feature allows the projector to be instantly powered on again, if it is accidentally switched off.

Wireless option
Instantly stream Full 1080p and 3D content from a Blu-ray™ player, set-top box, games console or AV receiver to your projector wirelessly; eliminating the hassle and extra cost of installing long cables using the WHD200 (sold separately).
