The Artlii Projector is bright enough to watch with the lights on. The audio is also miles above a typical projector with built in speakers. I bought this for watching movies in the living room with the kids for special occasions. We currently have just a small white blanket hung to watch tonight, but that is just the start. I plan to get a bigger portable screen that will provide a much better experience. Testing it I was able to get an really large projection, and the picture still looked great. I did notice, when the picture got bigger the picture brightness also wasnt quite as bright, but I guess that makes complete sense. The projection is bright and clear, the 1080 HD projection looks just like what you would expect from a 1080 HD projection. I was able to watch this with all the living room lights still on and still not have an issue watching it. I turned it on briefly during the day as well in a well lit room, and while it will project and you can see it, I would say it would be difficult to watch an entire movie on it without some straining. The audio output is loud enough that I had to turn it down right away. It is plenty of volume to drown out the fan noise of the projector. I was impressed with the stereo sound coming from the built in speakers. There was not a lot of low end, so if you like to feel your movies as much as you hear them you will want to plug in some external speakers with some rich low end, but if that is not you, you will be happy with the audio that is put out from this projector. The projector comes with 2 HDMI inputs, 2 USB inputs, VGA, and a memory card slot. Since this will be mainly for projecting from a computer I am not interested in the USB or memory inputs, but they are nice if that is of interest to you. At first I couldnt find any way to mount the projector from the ceiling, as I didnt see any mounting holes underneath. I was a bit disappointed because that is what I wanted to do with this projector ultimately. After a little bit of digging and checking I found that the mounting screw holes doubled as the holes that the feet were screwed in. Simply removing the feed and the projector is ready to mount, which I will be doing soon hopefully. The projector has a small stand that is part of the front of the projector. That stand is adjustable and will allow for tilting it up to project where you are trying to aim it. This coupled with the manual keystone correction helped it show a square picture where I wanted it without having to put it up on books or boxes.
