Review on Upgraded Version: 4500 Lumens Mini Projector - LED Portable Video Projector with 170'' Display, 1080P Support - Compatible with TV Stick, PS4, HDMI, VGA, TF, AV, USB by Ryan Olsen

I needed a simple inexpensive window video projector for Halloween and Christmas. I was hoping it could also be used to watch a movie with family. I was pleasantly surprised that it was all so easy to do. Attached photos and videos are projected onto a large white screen. It was a set of photophones my son ordered a few years ago that he doesn't use. The screen size of this projection is 10 feet! I downloaded some Halloween window projection videos to a USB drive and was able to run them just by plugging in the USB drive. You can select multiple files and they will keep repeating. I've tried a few things with movies. I connected my MacBook Pro to an HDMI adapter via the Displayport. It worked fine. I also connected an older Apple TV (2nd generation) via HDMI and was able to watch Netflix movies or share the screen with iPhone/iPad with no problems. The room was probably about 80% dark. You need a fairly dark image for the best picture, but that's what I expected. Not sure if it's 4500 lumens as its not listed in the spec in the manual. I've attached a photo of the spec page. It has small speakers, but you'll want to use something else. Fortunately, there is an audio output. I hooked it up to my Megaboom speaker and it sounded great. The fans are noisy but I would prefer them so they don't overheat. Just use an external speaker to drown out the fan noise. I've only had him for a few days.
