NEBULA Cosmos Max 4K UHD TV Home Theater/Entertainment Projector, Outdoor projector, Android TV 9.0 with 5000+ Apps, 360 ° of True 3D Audio, HDR10, HLG, Dynamic Smoothing (Renewed)

This is not the best 4K Projector out there since the ANSI lumens max is 1500, but the projector is outstanding for the price of 645 dollars, came with the original box and accessories and looks like it was new with new issues, I was a little concerned since it was refurbished but it works great. Great picture quality and great colors with a little fine tuning on the settings. I recommend setting brightness to 88 and picture mode to gamma 2.0, it's defaulted to enphoto setting. Also, adjust the color saturation to 55. See picture attached that shows the projector quality in a room with some light, looks even better at night with the lights out. Shows 4k HDR and HLG, looks amazing. While its not as good as my other XGIMI Pro 4K Projector, its not that far off and for 500 dollars less it's a great deal.

Horrible product stopped working after 6 months and they won’t honor a replacement ordered another one looked completely used worked for 15 minutes during set up and then stopped working again!

Update: dark scenes can be improved by changing settings. As other reviewers have said that this projector does not reproduce shadows well in dark scenes. I thought so too until I realized that there’s a thing called “Projector Settings” - what worked well for me was to go into Projector Settings > Picture Settings and change Picture Mode to Movie, Brightness to 44, Contrast to 50, then go into Advanced settings and change Gamma to Max Brite. For cine buffs, this gave the right effect in a darkened room for scenes with lots of shadow details. Okay, it’s not as good as other projectors rated at 1,000,000:1 contrast ratio but it’s MUCH better than the out of the box settings and I enjoyed the picture. The sound is phenomenal for a built-in speaker system. Not as good as a dedicated surround sound system but quite adequate, full range and loud enough for indoors. I also bought it for the low power rating, since I'll be powering it from my RV's batteries. I do recommend this projector.

Did not work

The picture is extremely dark especially with hdr. You can try to adjust with setting but then your whites will be washed out and have no detail and if you darken it, you won’t be able to see anything in dark scenes. I was going to upgrade from my 1080p epson ef12 and it’s not worth it even if they were the same price in my opinion. The cosmos is definitely crisper with the pixel shift 4K but the picture just doesn’t pop like the epson. There is no way that the cosmos is 1500 ansi lumens because I compared side to side to the 1000 ansi lumen of the epson and the epson blows it out of the water. I am returning it for those reasons. My advice, go with the ef12 for almost half the price.

The product itself looks sexy, modern and well built. Installation process was smooth and quick. Not many buttons or back and forth moving around set up, which makes it very convenient for a home projector type. Very recommended

I bought this projector refurbished but there is no way you would think it’s a refurbished unit. It came with everything and its own box as if it was brand new. Setting up the projector and configuring was a breeze and the picture quality is amazing even on the wall. I love it!!

Robust

I was looking to upgrade my current projector to get a 4K resolution. The cosmo max was on my short list after looking at reviews both from experts and buyers. I am glad I picked up the cosmo max. The picture quality is amazing and the inclusion of Google TV makes streaming so easy. The sound quality is great too but I am relying on my HT receiver. My only grip and why I am not giving 5 stars is that Netflix is not included this version of google TV (some issues with Anker?). You can use the Nebula app to get it but it's not very convenient. Using a Fire stick or Roku can easily solved the problem. I am very satisfied with my purchase given that I got it with the $600 coupon from Amazon.
