throw business projector

The InFocus SP2234ST is a DLP projector rated at 4200 lumens with a native XGA resolution of 1024 x 768 and a 30,000:1 contrast ratio. Its 0.617:1 throw ratio produces a 120-inch image from 1.5 metres, making it suitable for small meeting rooms and classrooms. The lamp lasts up to 15000 hours in normal mode.

Connectivity and image limits

Two HDMI 1.4 ports, one VGA input and one composite video jack handle video sources, while a 3.5 mm stereo mini jack accepts audio. The projector accepts signals up to 1920 x 1200 but displays them at the native 4:3 aspect ratio. Manual vertical keystone correction covers +/- 20 degrees and the lens offers manual focus only.

Upgrade path and trade-offs

The short-throw lens replaces standard-throw models that require more room depth, and the 15000-hour lamp life reduces maintenance compared to older 3000-to-5000-hour designs. Buyers who need widescreen native resolution, horizontal keystone adjustment or wireless networking will not find those features here. The fixed 0.617:1 throw ratio also prevents flexible placement at varying distances.
