While the contrast ratio of most projectors runs somewhere in the tens of thousands, the Optoma HZ45UST actually boasts a 3,000,000:1 ratio, ensuring extremely dynamic projection backed up by amazingly bright whites and immensely deep blacks. Here, 'UST' refers to ultra short throw, which means the projector can be set up conveniently close to the projection surface. In fact, the HZ45UST is able to cover a 100" diagonal screen size at a distance of just 30cm, making it the perfect HD projector for a professional home cinema set-up. Granted, it doesn't come cheap, but what you get in return for your hard-earned cash is a truly sublime viewing experience.
