Nebula Launches the Cosmos 4K SE: A Smart Portable Projector Equipped with Dolby Vision

All Industry News

Nebula has recently released the Cosmos 4K SE, an impressive upgrade for consumers who want portability without compromising on visual and audio quality. The Nebula Cosmos 4K SE, which retails for $1299, is designed to deliver a truly cinematic experience in a portable form factor. With 4K Ultra HD resolution and 1,800 ANSI lumens of brightness, it produces stunning images that can be projected on screens as large as 200 inches.

Whether you're watching movies in your living room or enjoying a film under the stars, the Cosmos 4K SE should deliver excellent image quality from a reasonably compact package.

One of the most notable features of the Cosmos 4K SE is its support of Dolby Vision®. This premium HDR technology utilizes dynamic metadata to enhance brightness, contrast, and color. Dolby Vision ensures that each frame of your movie or show is optimized for vivid detail, with deeper blacks and more vibrant colors. This means you’ll experience more realistic images, especially in scenes with varying light levels. The Cosmos 4K SE is not only one of the few portable projectors that support Dolby Vision, it's also one of the least expensive models.


In addition to Dolby Vision, Nebula has incorporated its self-developed NebulaMaster™ image processing engine, which improves overall color reproduction. This system, paired with the HybridBeam technology (a combination of LED and laser light sources), ensures a high brightness level while maintaining a wide color gamut—up to 70% of the Rec. 2020 color standard. As a result, the projector provides more accurate and natural colors, bringing everything from animated films to nature documentaries to life with breathtaking detail.

Regarding sound, the Cosmos 4K SE features a two x 15W speaker system that supports Dolby Audio, providing immersive sound to match the stunning visuals. Whether you're streaming a concert or watching an action-packed film, the audio quality ensures you’ll get a well-rounded home theater experience, even in outdoor environments where sound dispersion can be tricky.

The Cosmos 4K SE was designed with portability in mind, featuring an ergonomic silicone handle that makes it easy to carry between rooms or take on outdoor adventures. Weighing just over 9 pounds, it’s not the lightest projector on the market, but it strikes a balance between size and portability. Its compact design, combined with its durable handle, makes it easy to set up and transport, which is perfect for users who want to take their entertainment on the go.


The Nebula Cosmos 4K SE features Google TV™ with Netflix and over 10,000 apps, allowing users to easily access a wide range of streaming services and apps without the need for external devices. Additionally, both models come with advanced auto-setup features such as autofocus, keystone correction, auto obstacle avoidance, and ambient light adaptation, ensuring that your viewing experience is seamless, no matter the environment.

The newer Nebula Cosmos 4K SE looks similar to the more expensive Cosmos Laser 4K, another popular offering from Nebula. Both projectors offer 4K Ultra HD resolution, but the Cosmos Laser 4K has a higher rated of 2,400 ANSI lumens. This increase in brightness means that the Cosmos Laser 4K can perform better in well-lit rooms or outdoor settings during the day, where ambient light is more of a factor.

That said, the Cosmos 4K SE can deliver up to 1,800 ANSI lumens, which is sufficient for most home and outdoor environments, especially in the evening or under controlled lighting. Its HybridBeam technology, which combines LED and laser, balances brightness and color accuracy, ensuring that viewers get rich, vibrant colors without sacrificing brightness. According to Nebula, the Cosmo 4K SE can accurately reproduce 123% of the Rec.709 color space.

This makes the Cosmos 4K SE particularly strong in reproducing lifelike colors, especially with the support of Dolby Vision and the NebulaMaster™ image engine. While the Cosmos Laser 4K offers slightly higher brightness, the Cosmos 4K SE provides a more balanced approach to color reproduction and contrast, making it an excellent choice for viewers who prioritize color accuracy.

When it comes to sound, the Cosmos 4K SE features high-quality audio systems with dual 15W speakers and Dolby Audio support. However, the Cosmos Laser 4K offers a slightly more robust audio experience with more fine-tuned speaker arrangements, which might give it an edge in sound quality.

The Nebula Cosmos 4K SE comes in at a more affordable price point—$1,299—which makes it a great option for users looking for a premium 4K projector without breaking the bank. The Cosmos Laser 4K, on the other hand, is priced higher due to its laser-only light source and higher brightness capabilities, making it a more suitable option for those willing to invest in cutting-edge projector technology and brightness performance.

Overall, the Cosmos 4K SE offers a solid balance between price, portability, and performance, making it ideal for home theaters, backyard movie nights, and even camping trips. If you're looking for a versatile, portable projector that delivers stunning visuals and excellent color reproduction, the Cosmos 4K SE is an outstanding choice. Its Dolby Vision support, combined with HybridBeam technology, ensures that your movies, shows, and games are displayed in the best possible quality, whether at home or outdoors.

The new Cosmos 4K SE projector showcases Nebula’s commitment to delivering cutting-edge technology and portable entertainment solutions that fit seamlessly into modern lifestyles.
