Two-minute review

The Anker Nebula Cosmos Laser 4K is not your mean compact projector. It’s packing successful immoderate sizeable brightness and a laser lamp that marque for a high-quality representation successful a signifier origin you tin prime up and bring from country to room. With built-in speakers and an included streaming instrumentality that stashes distant down a cover, it adjacent has the accomplishment to powerfulness the full amusement setup for immoderate abstraction you bring it into. That’s not a atrocious connection for a $2,199 gadget.

2,400 lumens is plentifulness for a batch of scenarios, specified arsenic a acheronian backyard, a surviving country with a spot of ambient light, and adjacent a well-lit country arsenic agelong arsenic you’re watching agleam contented similar cartoons and sitcoms. With bully power of your ambient lighting, you tin bask an fantabulous representation retired of the Anker Nebula Cosmos Laser 4K that does an awesome occupation of balancing brightness with opposition portion providing that poppy HDR colour we’ve been getting utilized to. It doesn’t clasp a candle to the theater-level show of the Epson LS12000 oregon lucifer the colour of the triple-lasered Hisense L9G, but it’s not falling excessively galore steps down for a projector that costs good beneath fractional of those competitors. 

There are immoderate projectors that you tin get successful the aforesaid ballpark with a brighter 4K picture, but you’ll conflict to find immoderate that person the flexibility of the Anker Nebula Cosmos Laser 4K astatine $2,199 (about £1,740, AU$3,055). Some whitethorn beryllium cheaper, but they’ll often usage a accepted projection lamp alternatively of the overmuch longer-lasting laser airy root Anker has utilized here. Anker gets notable contention from the Optoma CinemaX P2 which we’ve precocious seen moving for $2,299 portion providing an adjacent brighter, laser-based picture, though it’s an ultra-short-throw exemplary that isn’t arsenic portable oregon flexible successful setup but would marque a amended dedicated location theatre display.

The Anker Nebula Cosmos Laser 4K has immoderate quirks to beryllium alert of. Action is handled poorly erstwhile there’s camera movement, making this an unideal enactment for enactment movie aficionados. Latency is besides an contented for gamers. It’s not truthful atrocious that casual gaming is retired of the cards, but it’s excessively dilatory for competitory oregon superior gaming. We besides spot immoderate unusual behaviour with HDR, but it’s precise intermittent and the benignant of happening that a hardware update mightiness resolve. 

The Anker Nebula Cosmos Laser 4K has plentifulness of competition, but if you privation a projector that volition regularly enactment successful a batch of antithetic places astir your home, determination are fewer options that volition bash it arsenic good and arsenic easy arsenic this one.

Design and features

  • Compact, easy-to-carry design
  • Projector, speakers, streaming instrumentality each successful one

The Anker Nebula Cosmos Laser 4K is simply a astonishing package. The portion is astir the size of a tiny picnic handbasket and truly feels similar 1 with its boxy signifier and grip cutting crossed the top. It’s a projector that’s made to beryllium easy carried. 

On the beforehand are a fig of sensors and a considerably ample lens for projection. Built-in sensors supply automatic absorption and keystoning, making it casual to get the projector acceptable up without having to dial done settings to finagle the nonstop positioning. The lens doesn’t person optical zoom, though, truthful you’ll person to settee for integer zoom to shrink the representation down to acceptable a space, and that means mislaid pixels and representation detail. The keystone is besides digital, meaning they’ll outgo you immoderate of the representation prime if used, truthful it becomes a question of prime oregon convenience. Theoretically, automatic framing is connected platform arsenic well, but we couldn’t get it to enactment successful our testing. 

Since this is simply a bright, laser-based beamer, Anker has included an eye-guard diagnostic that dims the lighting if it detects idiosyncratic excessively adjacent to the beforehand of the projector. Given the fig of times radical got caught looking straight into the beam during our testing, that’s a useful diagnostic to have.

The Nebula Cosmos Laser 4K is simply a implicit package. It’s lodging 4 speakers – 2 full-range speakers powered by 10 watts and 2 tweeters powered by 5 watts. It besides has a streaming instrumentality that slots into a tiny compartment connected the backmost of the projector. That’s convenient erstwhile moving the portion around, arsenic it’s not a escaped dongle sticking disconnected the back, and it’s perchance upgradeable oregon replaceable aboriginal connected down the line. Replacing whitethorn beryllium the much palatable move, arsenic the streaming instrumentality isn’t each that impressive. It often near america waiting for it to respond to inputs for acold excessively long. On the different hand, it does travel with due Netflix support, thing galore high-end projectors (like the Hisense L9G and each projector from Xgimi) proceed to lack.

In summation to the HDMI larboard utilized for the included streaming stick, there’s an HDMI larboard connected the backmost for an other video source. The streaming instrumentality tin nexus wirelessly to audio devices implicit Bluetooth 5.0 oregon the projector tin link to different speakers with a 3.5mm Aux cable. External audio is simply a bully thought successful general, though the speakers connected the projector dependable reasonably good balanced and bash a decent occupation successful a small, quiescent room. They won’t beryllium capable to powerfulness done a noisy country with radical talking oregon a instrumentality going, though.

While the projector tin person its picture’s keystone and zoom adjusted, it would person been useful to person adjustable feet to alteration the space of projection. As it is, we utilized a stack of tiny books to prop up either extremity for testing. 

The Anker Nebula Cosmos Laser 4K comes with a distant control, but it is oddly constricted to conscionable controlling the streaming instrumentality functions. Adjustment of representation settings similar focus, zoom, colour modes and specified doesn’t get handled by the remote. That means inconveniently utilizing the projector’s built-in buttons oregon its smartphone power app to navigate.

Picture Quality

  • Bright, 4K picture
  • Some HDR stumbling
  • Long-lasting laser airy source

The Anker Nebula Cosmos Laser 4K brings stunning show for a projector truthful compact. While a fig of different projectors we’ve tested similar the Hisense L9G tin service arsenic a home-theater-in-a-box, the Anker Nebula Cosmos Laser 4K is simply a location theatre to-go option. It peaks retired astatine 2,400 Lumens, which is sufficiently agleam for a semi-light-controlled environment. Drawing the blinds successful a surviving country and dimming the lights is capable to marque for a pleasant viewing acquisition successful the mediate of the day, portion implicit acheronian results successful a fantastic representation that lets opposition and colour travel done much robustly. It’s passable for casual viewing adjacent with darker contented successful a somewhat dim room, portion sitcoms and cartoons travel done rather good without managing the ambient light. And this is from our acquisition with the representation stretched good implicit 100 inches crossed our wall. Using a projector surface oregon reducing the size tin marque the representation adjacent better.

Now determination are cheaper projectors that tin get this bright, but Anker is bringing a 4K representation (still done pixel shifting) that’s sufficiently crisp adjacent erstwhile blown to ample proportions and adjacent if the representation pixel number is shrunk down done integer zoom and keystoning. That brightness is besides coming from a laser airy root with a specified longevity of up to 25,000 hours. There tin beryllium a small rainbow effect, but we hardly noticed it.

Screen sizes supported: 60-150 inches | 8K: No | HDR: Yes | Optical technology: Laser DLP | Smart TV: Yes (Android TV 10.0)| Dimensions: 10.4 x 8.7 x 6.5 successful | Weight: 10.7 pounds | 3D: No | Connections: HDMI 2.0 input, 3.5mm analog audio output; powered USB type-A, Bluetooth 5.0

We were blessed to spot that the projector doesn’t travel with abhorrent question interpolation moving retired of the box. Curiously, we didn’t spot immoderate question interpolation options. That whitethorn beryllium blessed quality for some, but it whitethorn stem from a deficiency of prowess successful this area. Watching Captain America: Civil War, we really noticed the projector struggling to support the playback creaseless during enactment sequences with a batch of quality and camera question going on. It wasn’t experience-ruining, but it was surely falling abbreviated of its contention and would marque it 1 to debar if you’re each astir enactment movies. That goes treble for superior gaming, wherever the question and noticeable input lag would basal successful the way. 

This wasn’t the lone contented we noticed successful the picture. With HDR enabled, we saw immoderate unusual quirks with however it processed definite content. Namely, Amazon’s Sneaky Pete would occasionally person scenes with the colors handled wrong, starring to immoderate bizarre posterization and colour banding. The contented didn’t harvest up successful immoderate different contented we saw, but it persisted crossed episodes from each 3 seasons of Sneaky Pete from some the included streaming instrumentality and a Chromecast with Google TV, and it would hap the aforesaid mode if we rewound to ticker the country again. This suggested that definite HDR signals are going to beryllium misinterpreted. The contented went distant with HDR disabled, but that leads to a importantly duller representation with a batch of the beingness sucked retired of it. HDR besides tin deepen shadows, which whitethorn marque it harder to spot contented without reducing ambient airy successful the room.

It’s not each atrocious for the HDR picture, though, which astir of the clip tin beryllium reasonably lush. The throne country combat country successful Star Wars: The Last Jedi was affluent with the reds of the scenery and characters, and the battle connected the rebel basal soon aft kept up the fantabulous representation quality.

You privation an enactment you tin truly instrumentality anywhere

You’re not excessively picky astir 4K

The brightness and solution definite bash brace good together, but if the 4K representation isn’t arsenic crucial, you tin prevention wads of wealth going with the Xgimi Horizon (the 1080p variant) oregon adjacent the 1080p Anker Nebula Cosmos Laser projector.
