HD PICTURE QUALITY HD picture quality was very good. It did a very good job displaying the fine detail of HD content. We did note some added edge enhancement processing, but it wasn't distracting. Color accuracy was very good, with flesh tones in particular, looking natural. Color temperature was slightly on the cool side, lending images a bluish tone. Contrast—the difference between the darkest blacks and brightest whites—was good, so images had depth and dimension. Black level was generally good, though not as dark as better performers on the darkest scenes (though quality does degrade as you move to the sides - see viewing angle). Image brightness was good (with the backlight control turned up), making it a suitable choice for most rooms. There was distinct banding (unnatural contours) on scenes with subtly shaded light-to-dark areas, such as a sky during sunset, rather than a smooth transition in the shaded areas. Film mode operation for HD film-based content was excellent, with no visible jaggies along the edges of objects during motion scenes. Deinterlacing was very good, with minimal jaggies visible when converting 1080i video content, such as from cable, to the display's native resolution.
VIEWING ANGLE This Insignia has a narrow viewing angle overall, below-average performance among TVs for this attribute. Only those seated directly in front of the screen will see the best picture quality. When we viewed the TV from the sides image quality degraded significantly. The picture showed a strong loss of color, so flesh tones looked very washed out. Black levels visibly brightened, reducing contrast especially on dark scenes. When viewing the image from above or below eye level to the screen, the vertical viewing angle was good. The picture showed some change in color, contrast, and black level.
