Samsung UN46B7100

Color Temperature (8.96)

Like anything that emits light your HDTV puts off a certain temperature of light. The industry standard for color temperature is 6500 Kelvin (K) and we adjust calibration on HDTVs to get as close to this number as possible. It's extremely important that color temperature stay stable whatever a television is displaying. This is because variations in color temperature can cause blue or yellow casts to the content on your HDTV. Below you can see a graph of the Samsung UN46B7100's color temperature across the greyscale, from black to white.

Color Gamut (4.32)

All HDTVs must display colors in the same way, matching an international standard known as Rec.709. This is done to ensure that the colors you see on your television are the same as the colors the creator of the content wanted you to see. Below you can see a graph of the Samsung UN46B7100's measured color gamut against Rec.709.

The Samsung UN46B7100 did not perform particularly well in this test. You can see from the graph that there was significant error across the board and especially in the blue to red range. This means that you can expect the colors on the UN46B7100 to be slightly off from the colors the content produce actually wanted you to see. Few HDTVs actually do well in this test, but the UN46B7100 was poor enough to fall below our average score of 5.31.
