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.
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.

Other projector picks
The other badge winners in our projectors ranking.
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.
