Display Criteria
1:1 Pixel Mapping Print

Applies To:  All Non-CRT Displays

1:1 Pixel Matching is required to ensure that a video signal that is identical to a display's native resolution is delivered to the display on a matching, pixel-by-pixel basis, without extraneous processing or scaling that could introduce visible artifacts.

Auto-Defeat Controls Print

Applies To:  All Display Types

Auto Defeat Controls are required to manually disable any automated or default display features, such as black level enhancement, flesh tone correction, digital noise reduction, etc.
Color Decoding Controls Print

Applies To:  All Display Types

Color Decoding Controls are required to accurately and independently adjust saturation and phase for each of the three primary color channels (red, green and blue).

Color Isolation Controls Print

Applies To:  All Display Types

Color Isolation Controls are required to evaluate the accuracy of a display's conversion of non-RGB signals to RGB, and to correct any conversion errors via the display's color decoder controls. Where physical isolation isn't possible, an electronic means is needed in order to view each color channel separately.

Color Management Controls Print

Applies To:  All Non-CRT Displays

Color Management Controls are required to enable digital displays to be correctly aligned to the primary and secondary color gamut of SMPTE-C, EBU, or HDTV color standards.
Discrete Source Controls Print

Applies To:  All Display Types

Discrete Source Controls refer to a system architecture that allows a display to be independently adjusted for more than one signal type or video source, and to have the resulting settings for each signal or source type stored separately and then applied correctly to the active video source or signal type.

Edge Enhancement Controls Print

Applies To:  All Display Types

Edge Enhancement Controls are required to minimize excess sharpness or edge ringing created by the display's internal signal processing.

Gamma Controls Print

Applies To:  All Display Types

Gamma Controls are required to achieve optimal light output at each measured step between video black and reference white.

Grayscale Controls (White Balance) Print

Applies To:  All Display Types

Grayscale Controls are required to allow adjustment of the levels of red, green and blue light that collectively produce the shades of gray that range from video black to reference white. Grayscale is also sometimes referred to as Color Temperature or White Balance, and while these three terms are not completely interchangeable, they all relate to how a television produces the "color of white" from a mixture of the red, green and blue primary color components.

Iris Control Print

Applies To:  All Digital Rear- & Front Projectors

Iris Control is used to adjust the light output of the display through the use of a lens-aperture.

ISF Certified Calibration Configuration (3C) Print

Applies To:  All Display Types

Certified Calibration Configuration, aka "3C," is an ISF-designed calibration system that manufacturers may incorporate into the design of their displays as a means of providing managed access to the controls needed for display calibration, including discrete controls for multiple sources and/or signal types and the ability to customize each source/signal type for day or night ambient lighting conditions.

Lamp or Backlight Controls Print

Applies To:  LCD Flat Panels; All Digital Rear- and Front Projectors

Lamp or Backlight Controls allow adjustment of the backlight or lamp brightness in certain types of digital displays.

Lens Shift Control Print

Applies To:  All Digital Front Projectors

Lens Shift Control allows a fixed-pixel front projector to mechanically reposition the lens in relation to the screen. Lens shift is indispensable in situations in which the projector cannot be mounted within the ideal range as specified by the manufacturer.

Y/C Delay Controls Print

Applies To:  All Display Types.

Y/C Delay Controls are required to minimize or correct artifacts that occur when the luminance (black & white) channel and/or one or more color channels in a video signal are not properly synchronized.
