There is no actual gamma standard for HDTV content, and people have different opinions about the correct one, but being able to choose one is important, and having a screen that doesn’t modify the projector’s settings is ideal.DIBELS® assessment tools and materials downloadable from this website (the "DIBELS Materials") are available to the educational entities listed below solely under the following conditions: Your use is not intended to and does not place the DIBELS Materials in the public domain. The gamma curve in a display accounts for this, making it so every incremental step is visible to you. If you have 255 light bulbs in a room, going from one light on to 2 lights is a much larger difference to your eye than going from 235 lights to 236. Gamma: The idea behind gamma is that your eye perceives changes in light levels in a non-linear way.This chart shows the HDTV color points inside of the CIE 1931 diagram. If a device can’t show all of these colors, or shows colors past them, the resulting image will look different from what it is supposed to. Otherwise the content would look completely different depending on what you watched it on. Because of this, we set a target for what these colors are in movies and TV shows and have display devices use those. We don’t have the technology today to show all the shades of red, green, blue, and other colors you see in nature. Color points: The colors the human eye can see are defined by the CIE 1931 chart, but no TV or projector can display all of those.It’s actually neutral, and the Cool setting is blue, fooling your eye. If you’re used to the Cool or Dynamic setting on your TV, D65 will likely seem reddish. HDTV and UHD use D65 as the color temperature for white, which is based on the midday sun in the Northern Hemisphere. The HDTV specification dictates a very exact neutral white. White can range from bluish white to reddish white. White point or “color temperature”: This is literally the color of white that you see on screen.
