User controls and media navigation are provided through an innovative on-screen menu that requires fewer steps to access the desired function and provides support in 16 languages. The ML300 travel projector is 3D capable, delivering XGA resolution 120HZ thru the VGA port (the equivalent of 3D-PC). The projector can deliver a 50-inch 3D image with plenty of brightness.

Single Source for Power, Efficiency and Durability

The Optoma ML300 provides a compact design and vivid LED performance. This highly-portable DLP projector allows users to share detailed presentations (with 3000:1 contrast ratio) without being hooked up to a computer.

Weighing in at less than 1.4 lbs. and measuring a compact 7.2” x 1.8” x 4.4”, the ML300 supports a variety of video signals, including HDTV (up to 1080p) NTSC, and PAL.

The media player is compatible with video file formats including H.264 (AVI, MOV, MP4 and 3GP), MPEG4 (AVI), Xvid (AVI), M-JPEG (AVI) and image file formats JPEG and BMP. The media player even plays back audio files such as MP3 and AAC. A microSD card slot for the ML300 allows for memory expansion up to 32GB. The ML300 is 3D capable, delivering XGA resolution 120 Hz thru the VGA port (the equivalent of 3D-PC). The projector can deliver a 50-inch 3D image.

LED Design Advantage

#1 DLP in the Americas

The ML300’s LED technology delivers low power and silent operation. The same LED technology provides vivid color, durability and long life that make it attractive to price-sensitive small business and consumer users. Featuring a wider color pallet, LED projector images appear to be brighter than lamp based projector images.

The LED light source has an estimated lifetime of more than 20,000 hours (equivalent to using the projector four hours every day for over thirteen years). LED is incredibly cost effective compared to lamp-based projectors. For example, users with a lamp-based projector would have to replace the lamp in the projector at least four times over 20,000 hours of usage—at a cost of over $800, compared to the completely maintenance-free LED lamp.

The LED-based design, in addition to being environmentally friendly with low power usage and the elimination of mercury and other hazardous materials, allows for cool operation which in turn allows for the compact size.
