Good news, 3D fanboys and girls, looks like Viewsonic’s back on the scene with a clutch of 120Hz 3D-enabled projectors. The first new model, the PJD6381, looks to be aimed at schools and businesses, with an extremely short throw ratios (around .68) for reducing shadowing effects, and a number of interactive whiteboard options. Available in August, this guy has 1024 x 768 XGA resolution, 2,500 ANSI lumens, a 2,500:1 contrast ratio, 120Hz refresh rate, and is compatible with the both Texas Instruments’ DLP Link and NVIDIA’s 3D-Vision 3D technology — expect it to have an MSRP of $1,249. The PJD6211 and PJD6221 ($849 and $899, respectively) also sport 1024 x 768 XGA resolution, as well as up to 2,700 lumens, a 2,800:1 contrast ratio and both DLP Link and 3D-Vision compatibility. These two should hit the stores some time in July.
