The Wohler HDM-550-4K is a high-performance 55", slim-bezel UHD 4K Broadcast Video Monitor designed for studio environments and playout and monitoring applications, as well as most other broadcast applications.
Offering four 3G/HD/SD-SDI and four DVI-D inputs, scaling, and quad-split functionality, this monitor allows for multiple displays options. You can have any four HD/SD SDI/HDMI/DVI inputs displayed in a quad-split in up to 1920 x 1080p60 resolution each; any single 3G/HD/SD-SDI or HDMI/DVI input upscaled to a single 3840 x 2160 UHD image; or a single UHD signal displayed in full resolution. There are also four 3G/HD/SD-SDI outputs.
The HDM-550-4K is an IPS panel with a 178° viewing angle, 1400:1 contrast ratio, 400 cd/m² brightness with an LED backlight, and 1.06 billion color depth. It has two built-in 5W stereo speakers, two RCA audio outputs, and 2-8 channel OSD audio meters for each display window. OSD functions also include tally, blue only, H/V delay, and audio/video lost alarms per display window. Control interfaces consist of eight GPI connections on DB9 ports, RS-485 on an RJ45 jack, and Ethernet 10/100M on an RJ45 jack.
The monitor features advanced 10-bit digital signal processing technology, plus a 3D comb filter, de-interlacer and highly accurate scaling. All this ensures the monitor portrays smoother, more natural image reproduction.
