Have you ever wished for a professional projector that offers the perfect balance between performance and portability? If so, the Optoma EH412ST Short Throw 1080P HDR Professional Projector may just be what we need.
Features and Specifications
Short Throw Lens
One of the defining features of the Optoma EH412ST is its short throw lens. This allows us to experience a large 120″ image projected from just 4.5 feet away. With a throw ratio of 0.5:1, it’s ideal for smaller spaces and makes installation remarkably easy. We can set it up closer to the screen, making it an excellent choice for rooms where space might be an issue.
High Brightness
The projector boasts 4,000 lumens of brightness. This means we can enjoy clear, vivid presentations even in well-lit environments such as meeting rooms, conference rooms, and classrooms. Brightness is crucial for ensuring that our presentations are visible to all participants, regardless of the room’s lighting conditions.
4K HDR Input
Another standout feature is its 4K HDR input. Paired with the latest 4K HDR video sources or 1080P HDR gaming content, this projector allows us to enjoy vibrant colors, brighter whites, deeper black levels, and sharper images. This is particularly beneficial for high-quality video presentations or gaming experiences.
Vivid Color
The Optoma EH412ST offers a 50,000:1 contrast ratio and a sRGB color profile, which ensures rich, accurate color representation based on the primaries of the Rec. 709 HDTV specification. Whether we’re using a PC, Mac, or any sRGB-compatible source, we can expect vibrant and authentic colors.

Connectivity is a key consideration for any projector, and the EH412ST does not disappoint. It features:
- 2 x HDMI

These extensive options make it easier to connect various devices, ensuring smooth and flexible presentations.

Long Lamp Life
One of the most impressive aspects of the EH412ST is its lamp life. With up to 15,000 hours of lamp life, we benefit from extended viewing time and a lower cost of ownership. This translates to an average of 5 hours of daily viewing time for over eight years, which is incredibly cost-effective.

As a result, we can immerse ourselves in a realistic 3D viewing experience. Note that 3D glasses are required for this feature and must be purchased separately.
DLP Technology
The EH412ST features DLP (Digital Light Processing) technology, which is a proprietary technology from Texas Instruments. DLP offers digital projection with higher contrast, faster response time, good pixel structure, and virtually no color degradation. Consequently, we can enjoy more precise and consistent image quality.

Keystone correction is also available, allowing us to adjust the image vertically and horizontally to eliminate any distortion.
Performance and Image Quality
Brightness and Clarity
The 4,000 lumens of brightness truly make a difference. Even in brightly lit rooms, the projector delivers clear and vivid images. Text remains sharp and readable, which is essential for presentations. The brightness level is more than sufficient for most professional settings, making it versatile and reliable.
Color Accuracy and Contrast
Color accuracy is another area where the EH412ST excels. With its 50,000:1 contrast ratio and sRGB color profile, colors appear rich and true to life. We notice the depth in the black levels and the vibrancy in the whites, creating a dynamic viewing experience. This level of color precision is particularly beneficial for presentations that involve graphs, charts, or any visual content.
4K HDR Performance
When paired with 4K HDR content, the projector truly shines. The enhanced brightness, deeper black levels, and sharper images elevate the presentation experience. Whether we are showcasing a high-definition video or engaging in a gaming session, the 4K HDR input ensures top-notch visual quality.

While it may not replace a dedicated audio system for larger venues, it is more than adequate for most professional environments.

For those of us who require more advanced audio capabilities, the projector’s audio in and out ports provide flexibility. We can easily connect external speakers or sound systems to enhance the audio quality. This adaptability ensures that we can meet the audio needs of any presentation setup.
