At the InfoComm 2009 show in Florida on Monday, ViewSonic announced the availability of its PJD6211, PJD6221 and PJD6381 projectors with 3D display capabilities thanks to their 120Hz refresh rates. All three have network management capabilities and multiple inputs, along with a focus on low energy consumption. The highest-end model, the PJD6381, offers one of the shortest throw ratios among DLP projectors on the market, at 0.68. It is compatible with whiteboards used in school districts across the US, and sports 1024x768 resolution, a 2,500 lumens brightness and 2,500:1 contrast ratio.

The 120Hz PJD6381 is compatible with Texas Instruments' stereoscopic 3D technology, DLP Link, as well as NVIDIA's GeForce 3D Vision. An Ethernet jack and management software lets users schedule powering on and off times and send maintenance e-mail alerts.

The PJD6211 and PJD6221 both have 1024x768 resolution and composite, S-Video and VGA inputs. A VGA output allows cloning the display on an external screen. The PJD6221 has a 2,700 lumens brightness and a 2,800:1 contrast ratio along with an Ethernet connection and network management software.

The PJD6211 and PJD6221 are coming out in July, priced at $849 and $999, respectively, while the PJD6381 will begin shipping in August, priced at $1,249.
