The quality and performance of a monitor depends on

  • A.Video Card, Refresh Rate, and Size
  • B.Size, Video Card. and Resolution
  • C.Video Card, Resolution, and Refresh Rate
  • D.Size, Refresh Rate, and Resolution

Answer: C

Correct answer: Video Card, Resolution, and Refresh Rate

These three between them determine what the user sees. The video card generates the signal and bounds what the monitor can be driven to display; resolution sets the number of pixels and hence the detail; refresh rate sets how often the image is redrawn and therefore the smoothness of motion.

Size affects how large the image appears but not its quality - a large screen at low resolution simply shows the same detail bigger, with coarser pixels, which is why the options including size are the weaker set.
