Milori Benchmark Measurements & Tests

As discussed in previous sections, the projector was calibrated for each screen to ensure the contrast, tint, hue, color and other factors, were as closely matched as possible in order to level the playing field for our observations and measurements. The results ensured that the projector and screens had been properly calibrated by providing the same RGB results over the entire IRE spectrum. Here are the adjustment parameters which were required to match these RGB curves.

As you can see, the Da-Lite required less brightness for equal measure, while the color needed to be increased. The Stewart seemed to need less color boost with equal brightness to the Carada screen, however, a slight decrease in contrast was noted as the projector required the most boost for this screen (with a value of 3).

Keep in mind that these observations do not necessarily depict that one screen was better than another, but it does show they are different. As you can see, each screen was able to be calibrated to provide virtually identical performance curves, but these measurements did verify that calibration using the right equipment was essential in optimizing the performance of the screen to the projector.

These measurements and the changes required to the projector do coincide with our visual observations. For example, the stewart and Carada seemed pretty close in relation to brightness but initially, the Carada appeared to absorb more color. Keep in mind the Stewart had a reflective coating on it (sparkly when you look at it from the right angle) and the Carada did not. We feel that the Da-lite required a higher color setting because the color was being somewhat washed out likely as a result of how brite the screen was. Again, the point here was that calibration is the key to optimal performance for any screen and projector set up.
