Lights on viewing – 3800 ANSIANSI ANSI lumens is a measurement of the total amount of visible light generated by a projector, as standardised by the American National Standards Institute (ANSI). It provides an accurate and consistent way to assess a projector's brightness, taking into account factors such as light output across the entire image, uniformity, and colour accuracy. ANSI lumens indicate the projector's brightness level, with higher values typically leading to better performance in spaces with ambient light or larger screens. lumens

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 gamutcolour gamut Colour gamut refers to the range of colours a projector can display. It is typically measured using the CIE 1931 colour space, which visualizes the range of colours visible to the human eye in a two-dimensional diagram. This colour space represents a projector's colour gamut, showing the specific colours that the projector can accurately reproduce. Rec. 709, also known as BT.709, is a standard colour gamut used in high-definition television (HDTV) and Blu-ray discs. It defines the colour space for HDTV with a specific range of colours that can be reproduced. The Rec. 709 colour space is smaller than the human eye's full range of colours, but it has been widely adopted for HD content production and display. On the other hand, Rec. 2020, also known as BT.2020, is a standard encompassing a significantly wider colour gamut than Rec. 709. It is designed to represent a much larger range of colours, closer to what the human eye can see. Rec. 2020 is often associated with ultra-high-definition content and next-generation display technologies, offering a more extensive palette of colours for more vibrant and lifelike imagery. The measurement of color gamut involves using a spectrophotometer or a colorimeter to analyze the projector's output across various wavelengths of light. This data is then plotted on the CIE 1931 color space diagram to visualize the projector's color gamut. This allows for a quantitative assessment of the projector's color reproduction capabilities according to specific color gamut standards such as Rec. 709 or Rec. 2020., 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.
Dynamic black technology
Dynamic black technology improves the depth of your image by smoothly adjusting the lamp output, based on the brightness information of each frame; to create a stunning high contrast ratioContrast Ratio The full on/off contrast ratio for projectors is a measurement that indicates the difference between the brightest and darkest parts of an image. It is obtained by comparing the luminance of the brightest white (full on) to the darkest black (full off) that the projector can produce. A higher contrast ratio typically results in images with greater depth, detail, and visual impact, making it an important factor in evaluating the quality of projected images.. Bright scenes appear crisp and clear, while dark scenes remain detailed with deep blacks and exceptional light and shade detail.
Full 3D
Display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting and the latest generation games consoles.
Game mode
Game mode optimises your projector for maximum contrast and vivid colours to capture every detail – leaving you time to focus on winning.
Integrated speaker
Complete your home entertainment experience with the convenience of a powerful built-in speaker for exceptional sound quality and an easy set up without the need for costly external speakers.
ISF modes
This feature allows you to save your calibrated day and night mode settings for the highest possible viewing experience.
24p
Most movies are shot at 24 frames per second (fps). To preserve the purity of the original image, Optoma projectors can accept high definition sources at 24 fps to display movies exactly as the director intended.
USB-Power
Use the USB-A port to power external devices (5V/1.5A)
Quick resume
This feature allows the projector to be instantly powered on again, if it is accidentally switched off.
Wireless option
Wirelessly stream Full HD 1080p and 3D content from a Blu-ray™ player, set-top box, games console or AV receiver to your projector; no cable management or installation required.

| Throw ratioThrow Ratio The throw ratio of a projector refers to the ratio of the distance between the projector and the screen to the width of the projected image. This ratio determines the size of the image based on the projector's distance from the screen, making it a crucial factor in choosing the right projector for a specific space. To calculate the distance between the projector and its screen using the throw ratio, one can use the following formula: Distance = Throw Ratio x Width of the Image For instance, if a projector has a throw ratio of 1.5:1 and the desired width of the image is 6 feet, the distance from the projector to the screen would be 1.5 x 6 = 9 feet. Understanding the throw ratio and its calculation is essential for setting up a projector to achieve the desired image size and optimal viewing experience based on the available space. | 1.47:1 ~ 1.62:1 |
