Just for fun, I took a few measurements of the Sharp in its Dynamic Fixed mode. Not much, but since our vision is very sensitive to flesh tones, it doesn't take much to shift them to either a bit pale or slightly orange. The flesh tone area is the small, pale orange space between red and yellow. I did notice, however, that the Sharp's flesh tones were a bit pale, and this chart may show why. The standard color space as defined by the ATSC standard is shown in the black triangle. While calibration, were it possible, might improve these results somewhat, they are quite respectable for a factory setting.įig.3 shows the Sharp's color points and the color space they define, as outlined by the white triangle. In this case there is too much blue (consistent with the temperatures in Fig.1) except at the very top end.

A necessary (but not sufficient) condition for this to occur is a color temperature of 6500K across the full brightness range. Ideally, the red, green, and blue lines should overlap at the 100% level. Fig.2 shows the RGB tracking in this setting. 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.

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. Adequate, but not cutting-edge.Įxcept as noted, all measurements were taken in the settings shown in "Settings," above. The measured contrast ratio and black level were fair. On-site, aftermarket calibration is not possible. The set's color is respectable out of the box in the Low setting, but not ideal. The images were sharp, clear, and detailed, limited only by the quality of the program material.
The Sharp's measured resolution was arguably the best we've seen from a single-piece display of any description.
