NEC MultiSync 84-inch ShadowSense Touch Interactive Flat Panel – X841UHD-2 SST
The NEC MultiSync X841UHD-2 SST (ShadowSense) is an 84-inch interactive flat panel with a 3840 x 2160 (4K UHD) S-IPS screen, 500 cd/m² brightness and ShadowSense touch that tracks 10 simultaneous touches. A pen and eraser are included. It is a discontinued model, and Procure.ae can confirm availability or suggest a successor in the UAE.
The X841UHD-2 SST combines an 84-inch S-IPS panel with edge LED backlighting, 1400:1 typical contrast and 178° viewing angles at native 4K resolution and 60 Hz. ShadowSense touch reports 12-bit touch resolution (4096 x 4096) and accuracy below 2 mm, with a touch response of 6 to 8 ms and ambient light rejection up to about 100000 lux. Input works with a finger, glove or stylus of 4 mm or more, and a zero air gap design avoids parallax.
Touch connects over USB 2.0 HID with native multi-touch on Windows 7 to 11, Linux and Android. Inputs include four HDMI, one DisplayPort and two DVI-D, and control is available over LAN with SNMP, RS-232C and IR. The OPS slot accepts a digital signage player, Slot-in PC and HDBaseT or SDI modules. Mounting uses a 400 x 400 mm VESA (FDMI) pattern, ST-801 feet, trolleys or the PDW T XXL wall mount.
