Color Temperature

The LV-8310 had some issues in this test, where we analyze the projectors ability to maintain a constant color temperature for whites across the range of intensities. We found that the whites shifted significantly, becoming warmer in the middle of the range and then cooler as they reached the darker end of the scale. The shift in both cases is not huge, but it persists over a large range of intensities, which could give those shades of grey a definite color cast.

RGB Curves

A projector should be able to accurately reproduce subtle color changes in the source, whether that is a graduated background in a Powerpoint slide or the blue sky of a movie. We found that the LV-8310 did a very good job here, accurately reproducing these changes. We test this by measuring a series of test screens that contain gradually changing colors, and measuring how well these changes are represented on screen. This test produces the graph below, where the ideal response is a smooth, clean curve. The LV-8310 gets close, although there are some minor bumps and jumps that show it is not perfect.

Color Gamut

The colors that a HDTV image contain are defined by a standard (called Rec.709), which contains the limits of the colors (called the color gamut). A good projector should stick to these limits, but we found that the LV-8310 was a little off: the red and green corners in particular were inaccurate, which would cause these colors to look different than the source material. This would be less of an issue for showing presentations than movies because the colors in presentations don't represent real life objects, but it is a definite issue for movie use.
