Optoma UHD38X: The Versatile 4K Projector

The Optoma UHD38X is a 4K UHD projector that offers excellent image quality, gaming performance, and versatile use. With a native resolution of 3840 x 2160 pixels, 4000 ANSI lumens brightness, and a dynamic contrast ratio of 1,000,000:1, it is suitable for various environments and applications.

Breathtaking Image Quality

The UHD38X delivers an immersive visual experience with its 4K UHD resolution. HDR (High Dynamic Range) technology and HLG (Hybrid Log-Gamma) compatibility provide more detailed images with richer colors and enhanced contrast. Dynamic Black technology adjusts black levels in real-time to optimize contrast and image depth.

The projector covers a wide color gamut, including 100% of the Rec.709 color space and a significant portion of DCI-P3, ensuring vibrant and accurate colors. Additionally, with effective 4K upscaling, even Full HD or lower-resolution content benefits from a noticeable improvement in image quality.

Unmatched Gaming Performance

The Optoma UHD38X stands out for its exceptional gaming capabilities. With an ultra-low input lag of just 4.2 ms in 1080p, it competes with dedicated gaming monitors. The Enhanced Gaming mode optimizes contrast and color vibrancy for an immersive gaming experience.

The 240 Hz refresh rate in Full HD ensures remarkable smoothness, ideal for fast-paced action games and e-sports competitions. These features make the UHD38X a top choice for demanding gamers using next-gen consoles or high-end gaming PCs.

Unparalleled Versatility

Whether for home cinema, gaming, or live sports viewing, the UHD38X adapts to all uses. Its ability to project images up to 300 inches diagonally (7.62 m) transforms any room into a true cinema.

Full 3D compatibility adds an extra dimension for fans of 3D movies and games. The projector supports various 3D formats, including Frame-packing in 1080p24 and 720p50/60.

Brightness and Contrast for Any Environment

With 4000 ANSI lumens, the UHD38X performs well even in brightly lit rooms. This high brightness, combined with a dynamic contrast ratio of 1,000,000:1, ensures sharp and detailed images in various lighting conditions.

The wall color adjustment feature is particularly convenient. It optimizes color rendering based on the projection surface, whether it’s a dedicated screen or a colored wall.

Durability and Energy Efficiency

The UHD38X’s lamp offers an impressive lifespan of up to 4000 hours in normal mode, 10,000 hours in Eco mode, and even 15,000 hours in Dynamic mode. This exceptional longevity reduces maintenance costs and environmental impact.

Various energy-saving modes allow you to adjust power consumption based on your needs. The standby mode consumes only 0.5 W, helping to lower energy bills.

Extensive Connectivity and Compatibility

The UHD38X features two HDMI 2.0 ports, ensuring compatibility with the latest 4K HDR sources. The audio connectivity includes a 3.5 mm input and output jack, as well as an S/PDIF output for easy integration into a home theater system.

The USB-A port with 1.5 A power supply allows you to connect and power devices such as wireless HDMI dongles. RS232 control ports and a 12 V trigger facilitate integration into advanced home automation setups.

Practical Features for Simplified Use

Horizontal and vertical keystone correction (±40°) ensures a perfectly rectangular image, even when the projector is not perfectly aligned with the screen. The 1.1x optical zoom provides additional flexibility for installation.

The backlit remote control makes it easy to use in the dark, while the built-in 10 W speaker allows for standalone use without an external audio system.

DLP Technology: Advantages and Considerations

The UHD38X uses Texas Instruments’ DLP (Digital Light Processing) technology, known for its responsiveness and ability to produce sharp and high-contrast images. This technology also offers excellent image uniformity, with an 80% rate across the entire projected surface.

However, it’s worth noting that some users may be sensitive to the rainbow effect, inherent to single-chip DLP technology. This effect is generally minimal and affects only a small minority of users.
