The Optoma CX305ST is a compact XGA short-throw projector designed for classrooms, training rooms and small business environments. Its short-throw lens can produce an approximately 80-inch image from only one metre away, allowing it to be installed close to the screen while reducing shadows and glare during presentations.
With 3,000 ANSI lumens of brightness, XGA resolution and an 18,000:1 contrast ratio, it delivers bright images, sharp graphics and clear text. Optoma’s BrilliantColor™ technology provides vibrant and accurate colours for educational and professional content. It also includes a built-in 2W speaker, dual VGA inputs, RS232 control and USB mouse functionality. Eco mode, sleep timer and low standby power consumption help reduce energy usage while extending lamp life up to 6,000 hours.
