The OPTOMA's GT5500+ 1080p ultra-short throw projector produces bright and colourful images with 3500 lumens and a 25000:1 contrast ratio, ideal for gaming, movies, and sports. From only 13" inches away, the super short throw lens projects a 100" image onto a wall-mounted screen or other flat surface. A built-in speaker delivers excellent sound, and two HDMI connections make the setup simple. Users can also use an HDMI dongle like the Google Chromecast, Amazon Fire Stick, or Apple TV to transform it into a smart projector so users can play games, stream videos, and share images on the big screen from the comfort of their own home.
