ViewSonic V3D231 3D Display - The Passive Approach

Despite the good brightness uniformity, the color uniformity of the ViewSonic is really not very good. The middle "row" of the display does well, with an average dE of 1.84, but the top and bottom of the display both have average dE values that are closer to 2.5. The overall average dE for the display is 2.31, but that is really brought down by the middle row. The upper left corner has a dE over 3, which is uncommon and indicates that there will be a clearly visible color shift for anything in that corner of the display. Looking at the breakdown by color, you can see the grayscale in the upper left has a very large shift, with a dE over 3 over the entire range. I was really quite surprised by the poor uniformity in color after the very good uniformity in brightness, as poor backlight uniformity is often the cause for color shifts around the display.

The color gamut for the ViewSonic is just sRGB and measured 73.15% of the Adobe RGB gamut. This falls in line with the color quality and the backlighting system, as the errors occur in those shades of blue that are at the edge of sRGB and it is not unexpected at all.
