It provides you with USB HDMI AUX input It has an external speaker that doesn't rely on the sound of the device you're connecting. The image is clear, and you can adjust the size of the content or movie being displayed, meaning you can move the device away and the image enlarges with you while remaining clear. The device is brand new. Its original price is 400, but I want to sell it for 200-250. This is my final offer, I swear by God.
