Astro DM-3400 4K2K LCD MonitorThe DM-3400 is a 56 inches 4K2K monitor corresponding to digital cinema 4K2K format or HD-SDI Multi format. This monitor copes with 4 input of DVI-D and 4 input of HD-SDI (Dual Link). In addition, Brightness, color temperature and gamma selection are possible with a wireless remote controller.
The DM-3400 monitor employs an ultra high resolution (3840x2160) LCD panel, four times that of HDTV (1920x1080). 8.3million pixels are displayed condensed on to a 56-inch screen, and without the screen-door effect common to fixed pixel displays, images with a fiuid texture and high resolution are displayed.
The DM-3400 delivers a high brightness of 500cd/㎡ and a high contrast ratio of 1200:1, so it is possible to see clear image without darkening the surroundings. The DM-3400 displays crisp 4K images in a variety of situations such as production sites including studios, in showrooms, and in meeting rooms.
The DM-3400 is equipped as standard with HD-SDI x 8 (YUV 4:2:2, RGB 4:4:4) and DVI-I x 4 (for digital signals only) input interfaces. It is also equipped with AES/EBU interface that can output demultiplexed embedded audio.
The DM-3400 displays not only ITU-R BT.1769 compliant 3840 x 2160 video dot-by-dot, but also supports the digital cinema global standard "4K"(4090 x 2160) promoted by the Digital Cinema Initiative (DCI), which is made up of hollywood film studio members. In addition, it supports multi-rate (60p, 60i, 24p, etc), detect field (frame) frequency and 1/1.001 automatically.
