Promethean EST-P1 DLP business projector 3000 lumens 1280x800

Ultra-short-throw DLP projector

The Promethean EST-P1 is a DLP business projector rated at 3000 ANSI lumens with a native 1280 x 800 resolution. It accepts 1080i HD video signals and delivers a 2500:1 contrast ratio. The unit weighs 19.8 lbs and is supplied in new condition. It suits classrooms or meeting rooms that need a bright image from a very short distance.

Placement and connectivity needs

Ultra-short-throw optics let the projector sit close to the screen or whiteboard, freeing floor space and preventing presenter shadows. An HDMI input handles the 1080i source signal, so a compatible cable and video source are required. The fixed native resolution of 1280 x 800 determines the sharpest image the chip can produce without scaling.

Sustained operation characteristics

DLP technology maintains consistent colour performance over long sessions because the colour wheel and micromirror array do not degrade like organic panels. The 3000 to 3500 lumen brightness range provides headroom for ambient light, while the 2500:1 contrast ratio holds black levels steady during extended presentations. The 19.8 lb chassis aids stable thermal dissipation.
