The PTDW530 can simultaneously display images from two sources onto a single screen. For example, you can display a PC image on the left & a video image on the right. Taking advantage of the wide-screen projection, this function gives you a host of new application possibilities to explore. With the advanced lamp modulation technology, the projector is now able to control the lamp intensity for each of the red, green, blue & white segments of the color wheel separately. Because the actual light output is controlled in relation to each color segment, light usage is optimized & color balance is obtained without lowering the brightness. This results in bright, vivid images with increased color fidelity.
