4K Dolby Vision home theater projector

The Nebula Cosmos 4K SE delivers native 3840 x 2160 resolution with Dolby Vision HDR for cinema-grade colour and contrast. Its HybridBeam light engine combines LED and laser sources to produce 1800 ANSI Lumens and 1.07 billion colours. Integrated Google TV streams 4K Netflix without an external dongle. The unit weighs 9.92 pounds and measures 10.26 x 6.5 x 10.33 inches.

Sustained brightness and colour stability

HybridBeam technology maintains 1800 ANSI Lumens output during extended viewing sessions without the brightness decay typical of lamp-based models. The NebulaMaster Image Engine continuously optimises grayscale, contrast and colour accuracy frame by frame. Dolby Vision metadata ensures consistent HDR performance across long movies or gaming sessions. Wall colour adaptation and ambient light adaptation preserve image fidelity as room conditions change.

Intelligent setup and installation limits

IEA 4.0 provides real-time autofocus, keystone correction, automatic obstacle avoidance and screen fit for rapid alignment on any surface up to 200 inches. The built-in handle allows portable repositioning between rooms. Eye guard pauses projection when objects enter the beam path. Installation requires a stable flat surface or compatible mount; the projector lacks lens shift, so vertical placement must align with the screen centre. Buyers needing ceiling mounting with lens shift or 3D playback should consider other models.

Questions about this item

How loud and hot does the Cosmos 4K SE get when running continuously for a full day?

The hybrid LED-laser HybridBeam light source produces 1,800 ANSI lumens while running cooler than lamp projectors, and the sealed optical engine keeps fan noise low enough for quiet rooms during all-day use.

What extra equipment do I need before I can start watching 4K Netflix on this projector?

Nothing beyond a Wi-Fi connection and a Netflix account — Google TV with 4K Netflix is built in, so no external streaming stick or dongle is required.

Will the IEA 4.0 auto-setup still work properly if I keep my older 1080p screen and AV receiver?

Yes, IEA 4.0 performs real-time autofocus, keystone correction, obstacle avoidance, screen fit and wall-colour adaptation regardless of screen resolution, and the projector outputs audio via HDMI and USB ports for your existing receiver.
