Specs, what owners report, who it suits and answers to common questions." canonical: https://vettedten.com/tech/projectors/nebula-cosmos-4k-se/ language: en-GB updated: 2026-11-09 score: 8.3 --- # Nebula Cosmos 4K SE review > **Our verdict:** The best projector in 2026 is the Nebula Cosmos 4K SE. It tops our ranking with 8.3 out of 10. No. 1 of 10 in our [projectors ranking](https://vettedten.com/tech/projectors/) · Updated November 2026 · [How we rank](https://vettedten.com/how-we-rank/) **8.3 out of 10** · Best Choice The Nebula Cosmos 4K SE is a 4K projector with Google TV and Netflix built in, so it needs no stick. It suits people who want a quiet, easy-to-set-up cinema in a room they can darken. Why it's here: - Google TV with 4K Netflix and no external dongle - Two HDMI 2.1 ports, one with eARC - Quiet at under 28dB, with two 15W speakers - Autofocus and keystone correction handle setup Keep in mind: - 1800 ANSI lumens is limiting in a bright room - No lens shift listed, so placement is less flexible - Speakers are modest, so a soundbar helps for films [Check price on Amazon](https://www.amazon.co.uk/dp/B0DCN1FN61) ## Why the Nebula Cosmos 4K SE scores 8.3 - How happy owners are: 4th of 10 - How many rated it: 4th of 10 - How new it is: 2nd of 10 ### No. 1 and No. 2 are level The Nebula Cosmos 4K SE and the BenQ TK700STi score the same, so either is a safe pick. The Nebula Cosmos 4K SE goes first because it is the newer design. No. 2 leaves owners a little happier. It takes our Best Premium badge. ## About the Nebula Cosmos 4K SE The Cosmos 4K SE is a DLP projector with a hybrid light source of RGB LED and laser, rated at 1800 ANSI lumens and 30,000 hours. Resolution is listed as 3840 x 2160. It runs Google TV, so Netflix in 4K and the rest of the Google Play apps are on the projector itself. Chromecast casting is supported. Expert Reviews found most major UK streaming apps available, with BBC iPlayer and Channel 4 often missing. The throw ratio is 1.2:1 and the image size runs from 60 to 150 inches. Expert Reviews puts a 60-inch picture at about 1.58 metres. Setup is automatic: autofocus, auto keystone correction, auto screen fit and obstacle avoidance. There is no optical zoom, and the brand lists no lens shift, so you place the projector to suit the screen. Two 15W speakers handle sound, with Dolby Audio. There are two HDMI 2.1 ports, one of them eARC, plus Wi-Fi and Bluetooth 5.1 (BLE). Noise is under 28dB. The projector needs mains power and has no battery, and it has a carrying handle. In the box are the projector, an AC cable, a remote, two AAA batteries and a quick start guide. ### Key specs - Resolution: 4K (3840 x 2160) - Brightness: 1800 ANSI lumens - Light source: RGB LED and laser (HybridBeam), 30,000 hours - Throw ratio: 1.2:1 - Image size: 60 to 150 inches - Operating system: Google TV - HDMI: Two HDMI 2.1, one with eARC - Speakers: 2 x 15W - Noise: Under 28dB - Warranty: Brand lists a Hassle-Free Warranty (length not stated on its page) and a 30-day money-back guarantee ## What owners report about the Nebula Cosmos 4K SE Owner feedback we could open for this model is limited, so this is a short picture. The pattern is positive on setup: owners say it is easy to get running, and the automatic sizing fits a projector screen well. They describe the picture as crisp and bright, and say the built-in sound is better than a typical TV's speakers. The recurring caveat is light. Owners say it does its best in a dim room, and a lit room washes the picture out. With no optical zoom, filling the screen depends on where the projector sits. One owner had a colour fault with reds that a replacement fixed, and said customer service was responsive. That is a single account, not a pattern. We found no owner reports on how it holds up after months of use. ## Who the Nebula Cosmos 4K SE suits The Cosmos 4K SE suits someone who wants a 4K picture and streaming from one box, in a living room or bedroom where the curtains can be drawn. It is quiet, sets itself up and has two HDMI 2.1 ports for a console and a soundbar. If you plan to add a soundbar for films, the eARC port is there for it. Look elsewhere if the room is bright most of the day. The BenQ TK700STi or Optoma UHD38x are brighter options in this guide. If space is tight, the BenQ TK700STi is the short-throw choice. If you want zoom for flexible placement, the XGIMI Horizon Ultra has optical zoom. ## Questions about the Nebula Cosmos 4K SE ### Does the Nebula Cosmos 4K SE have Netflix built in? Yes. It runs Google TV and plays Netflix in 4K through the official app, with no stick or dongle needed. It has a Netflix shortcut button on the remote. ### Is the Nebula Cosmos 4K SE bright enough for daytime? Only partly. It is rated at 1800 ANSI lumens. Reviewers found it copes with partial daylight, but dark scenes wash out with the lights on, and owners say it works best in a dim room. ### Does the Nebula Cosmos 4K SE have optical zoom or lens shift? No optical zoom, and the brand lists no lens shift. You set the picture size by moving the projector, with autofocus and keystone correction handling the rest. ### How loud is the Nebula Cosmos 4K SE? The brand lists under 28dB. One reviewer found the fan audible but not distracting except in very quiet scenes. ### Does the Nebula Cosmos 4K SE have a battery? No. It needs mains power (100 to 240V), so it must stay plugged in wherever you use it. ### How big is the Nebula Cosmos 4K SE? It measures 263 x 165 x 265 mm (H x W x D) and weighs 4.5 kg. It has a carrying handle on top. ## All 10 projectors, compared | No. | Product | Score | Badge | | ---: | --- | ---: | --- | | 1 | **Nebula Cosmos 4K SE** (this review) | 8.3 | Best Choice | | 2 | [BenQ TK700STi](https://vettedten.com/tech/projectors/benq-tk700sti/) | 8.3 | Best Premium | | 3 | [Epson CO-FH02](https://vettedten.com/tech/projectors/epson-co-fh02/) | 8.2 | Best Budget | | 4 | [Hisense M2TUK Pro](https://vettedten.com/tech/projectors/hisense-m2tuk-pro/) | 8.1 | | | 5 | [XGIMI Horizon Ultra](https://vettedten.com/tech/projectors/xgimi-horizon-ultra/) | 8.1 | | | 6 | [BenQ TK710](https://vettedten.com/tech/projectors/benq-tk710/) | 8.1 | | | 7 | [Epson EH-TW7100](https://vettedten.com/tech/projectors/epson-eh-tw7100/) | 8.0 | | | 8 | [XGIMI Horizon 20 Max](https://vettedten.com/tech/projectors/xgimi-horizon-20-max/) | 8.0 | | | 9 | [Optoma HD146X](https://vettedten.com/tech/projectors/optoma-hd146x/) | 7.9 | | | 10 | [Optoma UHD38x](https://vettedten.com/tech/projectors/optoma-uhd38x/) | 7.9 | | ## How we score it Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 26 models for this guide before settling on these ten. Brands can't pay to be included or to move up. We last checked these picks in November 2026.
