I have a screen that goes with it you can connect your phone if you have the cable or connect a Roku into it Technology The game changing technology in the MP150A is the use of Texas Instruments 720p DMD chip with IntelliBright® technology. The 720p chip uses DLP technology – used in 90% of the world’s digital theatre screens – and Texas Instrument’s new IntelliBright technology to dynamically adjust the projector’s brightness range for each individual pixel, based on the room’s ambient light. The result is a projected image with better contrast, clearer picture and increased energy efficiency. Increase efficiency means the device runs cooler, and longer, on each battery charge. Ultra-Portable Lightweight, battery operated and super compact, the MP150A brings HD projection to places it has never before been possible. Sales reps have easy access to projection on their terms and with their own equipment. Presentations on the fly, use web content, view presentations, YouTube videos – in any conference room or office with an available wall. Use for family gatherings, parties and celebrations whether at the park, in the driveway or in the extra bedroom – movies, photos and streaming content are all available. Built-in Battery and Speakers Take your projector away from the outlets and directly to your visual sharing space. The rechargeable battery in the MP150A will allow you to project for around two hours on a single charge. In addition, the two built-in 1-watt speakers will ensure you have sound wherever you are, and with the 3.5mm audio jack you can plug in your favorite external speakers for bigger sound.
