P553 SST

What the NEC P553 SST is

The NEC P553 SST is a 55-inch professional touch display built on a touch-overlay design, where a sensor layer sits in front of an LCD panel. Its ShadowSense touch technology tracks up to 10 touches at once, which suits group work on one screen. NEC has discontinued this model, so this page is written for organisations that already own one, buyers comparing it with newer displays, and anyone looking for a replacement.

Display and touch facts that matter

The panel is an S-PVA type with edge LED backlighting, a native resolution of 1920 x 1080 at 60 Hz and a typical contrast ratio of 4000:1. Brightness is rated at 550 cd/m², with a maximum of 700 cd/m². Touch accuracy is listed as below 1.5 mm and response time as 6 to 8 ms. The touch surface accepts fingers, gloves and styluses of 4 mm or more. The manufacturer rates ambient light rejection up to full sunlight, approximately 100,000 lux, which matters in rooms with large windows.

The front protective glass is 4 mm premium toughened glass with a single-sided anti-reflective coating and 92 percent light transmission, plus or minus 2 percent. The bezel measures 40 mm on each side, and the display includes integrated speakers rated at 10 W plus 10 W.

Connectivity and the OPS slot

• Video inputs: DisplayPort, HDMI, DVI-D and a 15-pin D-sub analogue input
• Audio: two 3.5 mm analogue inputs, HDMI and DisplayPort digital audio, and a 3.5 mm output
• Control: LAN at 100 Mbit with SNMP, RS-232C and a remote control wire input
• Expansion: an OPS slot, an interface extension slot and a DisplayPort pass-through output

The touch layer connects over USB 2.0 and is recognised without drivers on the host PC. Native multi-touch works on Windows 7 to 11, Linux and Android, while Mac OS and older Windows versions use the default mouse mode. The OPS slot accepts a plug-in PC, and the manufacturer recommends Intel Core i5 or i7 slot-in PCs with WS7P. The slot draws up to 61 W, which removes the need for a separate media PC in a meeting room.

Where it fits in Qatar

A private school in Al Wakrah fitting out a primary classroom could use this panel for shared reading and maths activities, with pupils touching the screen in groups. A team meeting room in West Bay could use it to annotate shared documents from a laptop connected over HDMI. A clinic reception area in Al Sadd could show wayfinding content, but only in an air-conditioned space. The operating range is 0 to +35 °C, and Qatar summer temperatures outdoors regularly pass 45 °C, so the display must sit indoors, away from direct sun through windows.

What to plan before ordering

The display weighs 37 kg without a stand and measures 1,328 x 789 x 79.1 mm. It has a 300 x 300 mm VESA pattern with M6 holes, so the wall structure must be checked before mounting. The front is rated IP40 and the back IP20, so keep dust and moisture away from the unit. Operating humidity is 20 to 80 percent. In the shipment setting, power use is 150 W in eco mode, and standby draws under 0.5 W. The box includes the display, remote control, DVI-D cable, power cable, USB cable and printed or CD manuals. The manufacturer gives a 3-year warranty that includes the backlight.
