Which tool should be used to check problems with intensity and hue of color information in a display?

Colorimeter
Vectorscope
Oscilloscope
Signal Generator

The correct answer is: Vectorscope

The best choice for checking problems with intensity and hue of color information in a display is the vectorscope. A vectorscope is specifically designed to analyze and display color information as vectors in a two-dimensional format. It helps in assessing the chrominance of video signals, providing insight into both the hue and saturation of colors. The vectorscope allows technicians to visualize where colors are located in the color space, making it easier to diagnose and correct issues related to color intensity and hue. In contrast, a colorimeter typically measures the brightness and the relative color intensity of displays but does not specifically represent the intensity and hue relationships as effectively as a vectorscope. An oscilloscope is useful for examining waveforms in electronic signals but is not designed specifically for analyzing color information. A signal generator is used to produce test signals for various applications and does not offer analysis of existing color data. Hence, the vectorscope stands out as the appropriate tool for evaluating color quality and issues related to intensity and hue in displays.
