Notes:
- After turning on the projector, press the Projector Settings button on top of the projector, then go to Advanced Settings > Projector Mode to select a setting.
- It is unnecessary to tilt the projector toward the projection surface. Your projector has autofocus and auto keystone correction to create a well-sized and clear image.
- For more control over projector height, you can place it on a tripod (sold separately).
- The distance between the projector lens and the screen determines the projector screen size.

Amazing brightness, quality and colors

I was in the market for a portable projector, not necessarily for camping but for movie nights and backyard parties. I did my research, read a lot of reviews and initially bought a Halo+. Though a good projector I quickly realized I have to go higher budgeting wise and as luck would have it amazon put this one up for sale during Prime days. I just paid a few extra hundred bucks (1080p version) than Halo+ but my goodness it was all worth it. We have been blown over by the image quality and we use the whole of white wall in basement (must be 160" projection image).

What I like about this projector:
Amazing brightness and colors
Ease of setup if you have a Google account and an Android device handy
Android TV is very fluid and snappy (I have used Samsung Tizen and LG Webos and none can match Android TV interface)
Remote can control both Projector settings and Android TV Dongle
Netflix is natively supported (very few projectors in the market has that feature and is a deal breaker for me )
Auto focus, Auto key-stoning and image adjustment
Sound quality is great , enough to fill my 20' x 14' Rec room in basement
Solid build

What can be better:
Its heavy at 11 bs, so u need a solid stand or tripod (I just put it on a small printer desk)
Lacks HDMI eARC support (for ATMOS lovers) though the sole HDMI port does support ARC

PS: My first foray in projector world and I am glad I jumped onto it.
