The Viewsonic PJD6544w comes out of the gate at $839.99 MSRP; an enticing price, considering the feature set.
Regarding the display tech, the PJD6544 uses a single chip 0.55" Texas Instruments DLP® technology. This means it is a .55 inch (diagonally) wide chip with a two-dimensional squared arrangement of 1-bit CMOS memory cells. These cells are essentially Aluminum Micrometer-sized mirrors laid out in 800 columns by 1280 rows along with a 149 micro pin grid array. In plain English for the newcomers here, each of the 1,024,000 (1280 x 800) micro mirrors act as positive/negative switches that determine the image’s clarity. The higher the number, the better the performance. In this case, the .65 TI DLP (WXGA) chip has slightly better in resolution than what you’d encounter with industrial and medical imaging devices. It also enhances presentations by enabling multiple worksheets/spreadsheets in one projection window in native 720p which was a big deal when it was introduced at InfoComm 2005. In essence, you won’t get short changed by the image for the price you are paying. Although it is definitely no SIM2 (example of higher end and trusted home theater brand) its function is adequate for the kind of roles you can use this projector which is educational or commercial.
Viewsonic produces this with contrast levels at 15,000:1. That sounds about right from what I experienced during the evaluation. The saving grace is that this is a native 16:10 with secondary 4:3 settings so contrast isn’t going to be a huge issue with most of its applications. Although I wasn’t thrilled by the contrast levels, I wasn’t put off by it either. It was a non-issue with my applications. Although home theater enthusiasts may take issue with this, this is not a projector that is made for home theater so it's a moot point.
