The Samsung HL-S5687W's principal feature is its 1080p native resolution, which means that its DLP imaging chip should be able to produce 1,920x1,080 pixels onscreen--see Performance for more. It achieves this high native resolution with the help of wobulation, a technology that effectively doubles the horizontal resolution; in reality, the DLP chip itself has only 960x1,080 discrete pixels, as opposed to LCoS 1080p displays that have all 1,920x1,080 discrete pixels (more info on DLP and wobulation). Of course all sources, including HDTV, computers, DVD, and standard-def, are scaled to fit the pixels. With 720p HDTV and lower-resolution sources, the benefits of 1080p are more limited.
