The 84" UHD flat-panel market is getting a bit crowded now that JVC has announced it will ship two models this month. The RS-840UD and PS-840UD both come from JVC Professional Products Company and are aimed primarily at commercial applications, such as video-production studios and trucks, medical imaging, and conference rooms. But they can also be used in upscale home theaters, and they are priced well below the other similar-size UHD flat panels currently available.
Both models offer 3840x2160 resolution with an IPS LCD panel, LED edge-lighting, 120Hz refresh rate, and 10-bit color depth. HDMI 1.4 inputs can accommodate UHD at up to 30 frames per second, and the display can accept 2160p/60 via four HDMI cables as well as from JVC's GY-HMQ10 compact handheld camcorder.
The only difference between the RS-840UD and PS-840UD is that the former includes ISF C3 calibration modes and the latter is compatible with Intel's Open Pluggable Specification (OPS), which is important for public digital-signage applications. So the RS-840UD is clearly the one to get for a home theater, and it offers a slight price advantage as well—$13,500 versus $14,000 for the PS-840UD. Either way, that's a lot less than the LG 84LM9600 for $20,000, Sony XBR-84X900 for $25,000 (though that one comes with a UHD movie server), and Samsung UN85S9 for $40,000, the only one at this size to offer a hardware-upgrade path to accommodate new versions of HDMI and other UHD developments as they become available.
