A:AnswerFor iPhones you need a lightning to hdmi cable and Android phones you need a hdmi to usb c cable. Or if you have a smart casting stick such as Chromecast, Amazon fire stick or Roku stick then you can cast from your phone.
A:AnswerIt does not come with a screen. I’ve been using it on my wall just fine. Don’t expect a lot for the price tho. The refresh rate isn’t fast enough for sports or movies. I mostly use it to watch cartoons or play Nintendo with the kids.
A:AnswerYes it can. I bought it for this same use. I would definitely recommend external speakers if you're using this in a big room. The projector comes with built in speakers but quality isn't great for bigger size rooms or the outdoors.
A:AnswerThe screen size can be changed between 75% and 100% without moving the projector using the settings from the menu. If the image still doesn't fit your screen area, you'll have to move the projector.
A:AnswerI have used it in a room with the lights off during the day that wasn't "pitch black" and the image can still be seen. Obviously, it works best in a dark room.
A:AnswerYou can use it for your Xbox using the HDMI cable. The resolution is only 720 instead of 1080 and it doesn't have a high refresh rate but it still should look good enough in a dark room.
A:AnswerIt has a 3.5 mm audio out. You will need a cable that splits from single 3.5 mm male to a red and white rca plug to hook up some external speakers.
