The results ranged from approximately 7100K at the low end (30IRE) to 6300K at the top (100IRE), with the mid level at about 6700K (60IRE). They also showed some non-defeatable edge enhancement.Īs noted earlier, aftermarket calibration of the Sharp LC-52D64U is not possible, so the results here were taken in the Low color temperature setting, which produced the best results (the next higher setting, Mid-Low, produced a color temperature of approximately 7600K).įig.1 shows the grayscale in the Low setting.
SHARP HDTV DOT BY DOT SETTING 480P
The 480i and 480p sharpness patterns were also good, though as expected quite soft compared to 1080i. I used a Sharpness setting of -4 for most program material. At 720p, the line was noticeably softer-though this had not been evident on the multiburst patterns (above). While the component line was cleanest at a Sharpness setting of -2, the HDMI looked best at -7. The standard definition responses at 480i and 480p were satisfactory overall in both black and white and color, though again a bit better in component than in HDMI.Ī sharpness pattern at 1080i, in either HDMI or component, produced a superbly crisp 1-pixel line. But given a reasonable color response, which the Sharp has, it's the luminance response that dominates the detail we see, and the Sharp's HD luminance response is superb. The color response was slightly less impressive, but still good (and surprisingly a bit better, at its best, in component than HDMI at 1080i). The multiburst luminance (black and white) response of the Sharp (as displayed from my AccuPel HDG-3000 test pattern generator) was excellent over both HDMI and component to the maximum 37.1MHz luma burst. Except as noted, all measurements were taken using the adjustments shown in the "Settings" secton.
