Final answer:
Horizontal resolution, vertical resolution, contrast, brightness, and lag determine television image quality.
Step-by-step explanation:
Horizontal resolution, vertical resolution, contrast, brightness, and lag are factors that determine television image quality.
Resolution refers to the number of pixels used in an image, and higher resolution results in a clearer image with more detail. Contrast and brightness determine the range of colors and the overall vibrant appearance of the image. Lag refers to the delay between the input signal and its display on the screen, with lower lag providing smoother motion.
