Comments about Samsung Samsung 56" DLP Projection HDTV:

I bought this TV 28 days ago, it will be returned, as I feel DECEIVED by Samsung. This TV is NOT a "True 1080p HDTV". Unlike LCD and LCoS (also called D-ILA or SXRD) that have a full set of 1920x1080 pixels. [...] I finally got an anser to my question...What DLP Chip Set is in the TV? And the answer is the "xHD3" DLP Chip. This TV does have a 1080P picture, but the xHD3 DLP chip does not actually have a resolution of 1920x1080. The "effective" resolution spec is not derived from a physical, hardware-based measurement, the way native resolution is. Rather, by using a DLP-based technology called Wobulation, or SmoothPicture technology, effective resolution denotes only a PERCEIVED resolution. Effective resolution will not be promoted. Rather, it will be kept somewhat hush-hush. Indeed, the press materials for the rear-projection displays that use Wobulation or SmoothPicture specify the displays at 720p (1,280 x 720 pixels) and 1080p (1,920 x 1,080 pixels), when in fact their actual native resolutions, in a traditional sense, would be about half those figures. Basically, Wobulation or SmoothPicture asks each DLP micro-mirror to do double-duty, directing light instantaneously for more than one pixel of data. A small "wobbling" mirror placed in the projector's internal light path, which is independent of the DLP chip, does the rest. 640 x 720 mirrors for 720p displays and 960 x 1,080 mirrors for 1080p displays. What people see on the display appears to be a full 720p or 1080p image. The perceptible dots of light or "pixels" seen on the display is 720p or 1080p resolution.
