Automatic ➤ Convergence
ACON is an automatic convergence feature. Convergence of the red, green and blue images is performed accurately and automatically with minimal user intervention.
A process whereby a display setup for a given source is approximated from other setups already in memory. For more information about ASI, refer to the ASR entry in section 3.7, Utility Features.
A process whereby a display setup for a given source is chosen from memory according to its signal parameters (horizontal and vertical frequencies). For more information about ASR, refer to the ASR entry in section 3.7, Utility Features.
The time, inside one horizontal scan line, during which video is generated.
The ability of a screen to reflect ambient light in a direction away from the "line of best viewing". Curved screens usually have good ambient light rejection. Flat screens usually have less ambient light rejection.
The video output of most computers and video tape machines. Analog video can generate a large number of colors.
The ratio of the width of an image to its height.
The automatic alignment of the projected red, green and blue images on the projection screen.
