This week on HD Nation, the hosts review two of Optomaâ€™s portable projectors, the PK320 and the ML500. They were fairly impressed by the small size being able to deliver incredible image quality. The image quality for both devices is good for business applications, but not really suited for home theater entertainment. In the other major segment on this weekâ€™s episode, the hosts handle one of their viewersâ€™ questions that ask for more details about the 21:9 aspect ratio. This aspect ratio is the same ratio that most movies are filmed in originally. By using this ratio in a TV screen, the black bars above and below the screen are eliminated from the overall display.
