Test Bench: Samsung HL-S5679W 56-inch LED DLP HDTV

Color temperature (Movie Mode/Warm2 Color Tone): 20 IRE: 7,051 K 30 IRE: 6,564 K 40 IRE: 6,590 K 50 IRE: 6,584 K 60 IRE: 6,596 K 70 IRE: 6,535 K 80 IRE: 6,571 K 90 IRE: 6,559 K 100 IRE: 6,590 K

Brightness (100-IRE window): 35.3 ftL

With the Samsung's Movie Mode and Warm2 Color Tone presets selected, its grayscale hit the 6,500-degree kelvin standard right on the nose; no additional tweaks were required. Grayscale tracking measured within ±60 K from 30 to 100 IRE. That's outstanding performance, although a considerable degree of color decoder error (-20% red and -10% green) showed up in Movie Mode via the HDMI and component-video inputs. Color points, which describe the accuracy of the red, green, and blue primary colors, were extremely accurate - the HL-S5679W measured better in this respect than any other HDTV I've tested.

Overscan, which is the amount of picture area cut off at the edges of the TV's screen, measured 5% for both the HDMI and component-video inputs - a higher than average amount. Picture geometry was fair, with slight bowing visible at the edges of the screen on test patterns, but not on regular programs. And picture uniformity ranked relatively low because of hotspotting at the screen's center that was visible at both centered and off-center seats. This caused a color-tone shift than was most apparent on test patterns and black-and-white movies but visible on ordinary color programs as well.

The Samsung came up just shy of displaying the full resolution of 1080i-format test patterns via its HDMI inputs, while the same patterns viewed through its component-video connections looked comparatively soft and noisy.
