Short-throw projection
This projector can project large images from a short distance, meaning you can get an image up to 100 inches from just under a meter away.
Big Screen Entertainment
Create and view images far larger than any television with a projector. You can create an impressive image up to 300 inches*. Perfect for an immersive cinematic experience in the comfort of your own home.
*Image size depends on available space (wall size and distance) and ambient lighting conditions.

Bright images even in daylight
This all-round home entertainment projector combines high brightness and rich colors for a vivid, lifelike image in brightly lit environments - ideal for watching TV, sports, movies, or gaming with family or friends at any time of day.

4K UHD resolution
With more than 8 million pixels, 4K UHD resolution brings four times more detail to the screen than Full HD, delivering sharp, lifelike, and rich colors. So you can sit even closer to the screen and truly immerse yourself in the image.

Rich colors
Whether it's movies, TV shows, or video games, Optoma projectors deliver impressively rich colors in any environment and for any content. Our home theater projectors use the Rec. 709 color scheme, the international HDTV standard, to ensure accurate color reproduction.

Advanced Gaming Mode
Advanced Gaming Mode optimizes your projector for maximum contrast and vibrant colors to capture every detail. It also reduces input lag to as low as 4.2 ms (1080p 240 Hz), resulting in lightning-fast response times.
Note: When this setting is enabled, some settings will be disabled. See the user guide for more information.*

240Hz Smooth Motion
Enjoy ultra-smooth, fluid motion and reduced lag. A high refresh rate makes it easier to follow the action, allowing you to hit your target sooner. Ideal for fast-paced action games.
HLG compatible
Suitable for receiving and displaying Hybrid Log Gamma (HLG) HDR content. HLG-compatible Optoma projectors allow you to see even more detail and texture. Objects appear more solid and lifelike, and the added detail creates a greater sense of depth, as if looking through a window. (UHZ65UST and P2 only via USB)

ISF modes
This feature allows you to save the day and night modes calibrated by an ISF technician.

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

Jump into the game and enjoy an immersive, life-size experience on a large screen that's significantly larger than a conventional TV at up to 300 inches*. The larger split-screen area also makes multiplayer games more engaging.


Built-in speaker
Complete your home theater experience with the practical built-in speaker. It delivers great sound and saves you the time and effort of buying additional speakers.

24p
Most films are shot at 24 frames per second (fps). Optoma projectors can detect HD sources and display films at 24 fps as the director intended.

USB Power
Use USB power to power an HDMI dongle, such as Google Chromecast.
Horizontal Keystone Correction and Four Corner Adjustment
Whether it's horizontal or vertical keystone correction or four-corner adjustment for even images, this projector can do both. It's also suitable for unusual placements with uneven walls or similar.
Set wall color
Don't have a white wall or projection screen? No problem! With the "Wall Color" setting, you can adjust the projected image to match the color of your wall. You can easily choose between six options for blackboard, light yellow, light green, light blue, pink, and gray walls to achieve the most accurate color space possible.

Illuminated remote control
Our backlit remote controls feature subtle white LEDs to ensure the buttons are clearly visible and easy to use, even in the dark.
