10. Display Quality: Brightness and Contrast

The Tecra A8's display showed a good level of brightness, with a mean brightness level of 127 candelas/m². The minimum brightness level was 109.3 candelas/m² and the maximum was 145.8 candelas/m², resulting in a brightness range of 37 candelas/m², which indicates a quite evenly lit display as the brighness chart for the A8 shows.

Mean contrast of the Tecra A8's display is somewhat less than stellar at 107 candelas/m²; minimum and maximum contrast are 72 and 127 candelas/m² respectively, for a range of 56 candelas/m² and a fairly uneven cross-display contrast. The M7's results, which follow, put the A8's numbers to shame.

At 153.49 candelas/ m², the M7 boasts a better mean brightness than the A8. The minimum brightness of 116 candelas/m², the maximum brightness of 171.4 candelas/m² and a brightness range of 55 candelas/m² show a display with somewhat less even brightness than the A8.

The mean contrast level for the M7 came in at 469 candelas/ m², which is more than four times better than the number we found for the A8. A minimum contrast of 377 candelas/ m² and maximum of 551 candelas/ m² along with a range of 174 candelas/m² tell us that, with its higher contrast, the M7 actually has a more even distribution of contrast than the A7. You can see that in the smoother 3D curve.
