The Optoma W319UST is a bright short throw projector. At 3300 lumens you can project throughout the day with the blinds open and with it being a short throw projector, the image will appear bright and clear. The image will also be really crisp; with WXGA resolution it is perfect for presentations, video clips and any other data, and will be compatible with all modern laptops and the pixels will not be stretched. The short throw ratio means you can project a large image from just a short distance from the screen. As a short throw projector, it eliminates shadows on the screen and allows you to present with ease. Crisper whites & ultra-rich blacks make images come alive and text easier to read from the high contrast ratio. The W319UST has HDMI connection which will allow you to connect to most devices and show your content in high spec. There are also two VGA ports so you can connect to two sources at the same time without swapping cables around. The 12V trigger allows the screen to come down automatically when the projector is turned on. The extensive RS232 command set makes it simple and easy to control with any RS232 control system. The 16W built in speaker is ideal for a medium sized audience with no additional audio needed. Overall, this is a great short throw projector with modern features.
