NEBULA Cosmos 4K SE Smart Projector, High-Brightness with Dolby Vision, 200" Screen, 1800 ANSI Lumens, HybridBeam, Enhanced Image Quality, GTV, Portable, for Gaming, Home, and Office Use (Renewed)

What catches my attention is the image quality and the features. Outstanding quality for the price and the image adapts wall, screen and anywhere.. Impressed on the sound quality and performance. The keystone and auto focus are exceptional and very responsive and allows integrate effectively with Bluetooth.

I searched 4k projector for 1 month. bought Hisense c1 but returned. Finally ..I bought before 1 week. Watching 4 hours /everyday. Nebula cosmos 4k is excellent. Image quality and contrast and brightness is perfect. I love cosmos 4k.

The quality is excellent! I am happy with the purchase.

Picture quality was nice. The overall the screen wouldn't adjust to the proper size of my aLR screen, so I ultimately had the return it. I didn't want to, but overall couldn't use it

The NEBULA Cosmos 4K SE delivers crisp 4K UHD picture quality with Dolby Vision support and vibrant color reproduction, making movies and shows look stunning on a big screen up to 200″. Its HybridBeam light engine and 1,800 ANSI lumens brightness bring rich images even in moderately lit rooms, while built‑in Google TV offers seamless access to streaming apps without extra devices. Setup is easy with autofocus, auto keystone, and wall‑color calibration, and the included speakers provide surprisingly solid sound for casual viewing.  However, contrast and black levels can fall short in darker scenes, and the software UI may feel sluggish at times—issues that keep it from being truly premium. Still, it’s a great all‑in‑one 4K smart projector for home cinema on a mid‑range budget.

The overall picture Quality of this projector is really good, I am impressed with solid sound and ease to use. Remote control is easy to operate but the screen size of this projector is not at all bigger than 110 inches, if you move the projector back then picture quality drops drastically

As good as 4k tv in picture quality but much larger image

This is an awesome projector. The WiFi is a little finicky as it has not yet updated to WSP3 so you might have to create a guest WiFi to lower the security level of your WiFi. Other than that this is amazing.

--One year review-- After LESS THAN A YEAR of light use, up to twice a week, the unit has no longer functions correctly after Anker forced a firmware update. Amazon should state clearly that warranty is only 3-months. The projector costs over a thousand dollars and breaks within one year...I took very good care of my Anker projector and even if I spent $1300, I treat the projector like I paid $10,000. Ultimately, the quality of projector is not good if the unit lasts only less than a year. Despite my efforts to prolong the lifespan of the Anker Nebula Cosmos 4K SE, Anker themselves broke it with their firmware update. --Original Review-- I read great reviews about the Nebula Cosmo 4K SE, so when I saw a refurbished model on sale I jumped to the chance to buy it right away. The price was too good to pass up. One thing that is understated in user reviews is the low contrast ratio. Even in a dark room with velvet wall curtains to absorb bounce light, the blacks levels on the projector are worse than bad. Another note is that this projector isn’t true native 4K. It uses a 0.47-inch native 1080p micromirror DLP chip that achieves 4K-like picture quality using pixel shifting technology. It’s 1080p native but shifts the sensor to a degree that it fakes a 4K image. Given the price point at which I bought it at, the image quality is fine minus the black levels. Another flaw about the projector is that it requires 1.5 meters for the auto keystone to come into effect. Out of the box I thought I got a lemon unit because the projector kept giving me a sensor error as it failed to keystone or focus. After moving the projector approximately 1.5m away from a wall the auto keystone worked as long as I go into the screen menu. Using the auto keystone button on the controller always led to a sensor error. Perhaps I did get a bad unit or it’s just a quirk of the firmware. The problem with video reviews on YouTube is that they don’t mention any of these issues about the required distance and janky auto keystone functions. I’ve had the projector for about 2 weeks and I must have seen the “Contact support” popup window at least 30 times. But, again…due to the price point, I can live with a few quirks. If your budget is under CAD$1400 after taxes this unit is fine….but if you have a larger budget of $CAD10,000 before taxes, save your money for a true 4K projector. This unit was in my price range….if you can afford something better, don't buy the Cosmos 4K SE.
