Test Bench: Eight Budget HDTV Projectors
Except where noted, we used the digital (HDMI or DVI) input with sources set to 720p resolution. Contrast ratio was measured after calibration using a checkerboard pattern. We used a signal generator and DVDs to check primary color accuracy, color decoding, resolution, edge enhancement, uniformity, black-level retention, and overscan. Standard-definition video processing was evaluated with the Silicon Optix HQV Benchmark DVD. Test hardware included a Denon DVD-5910 DVD player, a Sencore VP403 signal generator, a Dish Network DVR-942 satellite HD receiver, and component-video and HDMI distribution amplifiers.
