Panasonic PT-FRZ55 adds a new Dynamic Contrast 2 setting to its Dynamic Contrast function, which uses digitally controlled scene-linking to directly modulate laser output, to further enhance contrast accuracy. The Quartet Color Harmonizer boosts vibrancy while Rich Color Enhancer adjusts wheel-timing to optimize image quality to suit different picture modes. The Panasonic PT-FRZ55 Projector operating noise is suppressed to an inaudible 27 dB in Quiet Mode. Improved installation flexibility while 4K signal input via CEC-compatible HDMI® and DIGITAL LINK smooths integration with 4K infrastructure. There’s a separate LAN terminal, and a 5 V/2 A USB outlet to support wireless projection. It also features a high-efficiency filterless cooling system, hermetically sealed DMD block, and dust-resistant shielded laser drive to assure 20,000 hours of stable maintenance-free projection. A linear brightness ramp and strong color retention preserve image quality for longer.
