Enhanced gaming mode
Enhanced gaming mode optimises your projector for maximum contrast and vivid colours to capture every detail. It also reduces input lagInput Lag Signal input lag for a projector refers to the delay between the moment a signal (such as a video feed from a computer or gaming console) is initiated and when it is displayed on the projector screen. This lag occurs due to several factors, including signal processing, resolution scaling, and refresh rates. It is particularly important for activities requiring immediate feedback, such as gaming or live presentations, where even a slight delay can disrupt the experience. Measuring signal input lag in milliseconds (ms) helps users evaluate a projector’s performance. Lower signal input lag ensures a smoother and more synchronised viewing experience. down to as little as 4.2ms (1080p 240Hz) for lightning-fast response times.

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.

| 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. | 2,500,000:1 |

| Keystone correctionKeystone Correction The keystone adjustment feature on a projector corrects the trapezoidal distortion of the projected image that can occur when the projector is not perpendicular to the screen. This distortion happens when the projector is tilted vertically or horizontally, resulting in a skewed or trapezoid-shaped image rather than a perfect rectangle. The keystone adjustment allows users to digitally manipulate the projected image's shape, correcting the trapezoidal distortion and ensuring that the image appears rectangular and proportional. This feature is especially useful when the projector cannot be placed directly in front of the centre of the screen due to space constraints or mounting limitations. By adjusting the keystone settings, users can align the projected image with the screen, resulting in a more accurate and visually pleasing display. – horizontal | 30° |

| 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. | 1.21:1 ~ 1.59:1 |

| Connections | Inputs 2 x HDMI 2.0, 3 x USB-A, 1 x HDMI 2.0 (eARCeArc eARC, or enhanced Audio Return Channel, is an HDMI feature that enables high-quality audio signals to be transmitted from a television to an audio system or soundbar using a single HDMI cable. This advanced feature allows for the transmission of uncompressed and higher bandwidth audio signals, supporting formats such as Dolby Atmos and DTS:X for immersive audio experiences. The main difference between ARC (Audio Return Channel) and eARC lies in their capabilities. ARC, which was introduced with HDMI 1.4, allowed for audio to be sent from a television to an audio system over an HDMI cable. However, ARC had limitations in terms of bandwidth and supported audio formats. On the other hand, eARC, introduced with HDMI 2.1, represents a significant advancement over ARC. eARC offers higher bandwidth and supports advanced audio formats, enabling the transmission of high-resolution, uncompressed audio, including object-based audio such as Dolby Atmos, directly from the TV to external audio devices. This results in improved audio fidelity and a more immersive audio experience compared to the limitations of ARC. In summary, the key differences between ARC and eARC are the bandwidth capabilities and support for advanced audio formats. eARC provides a superior audio transmission solution, especially for high-fidelity audio and immersive audio formats, compared to the original ARC standard.)
