For optimal results in meeting rooms, position the projector so the projected image fills the intended screen area while keeping the projector’s distance within the lens throw range. Use source devices set to the projector’s native resolution (1920x1200) when possible, and allow the projector to warm up for consistent color and brightness. Regularly clean the lens and air filters according to the manufacturer’s maintenance schedule to maintain image quality and cooling efficiency.
