What is response time?

What is response time?

• A. How long in milliseconds the monitor takes to update its pixels
• B. Time to boot the computer
• C. Delay before the OS detects a device
• D. Time to transfer data over USB

Answer: (A)

Response time is the time it takes for a pixel to change from one color to another on the display, typically measured in milliseconds. This tells you how quickly the screen can update its image, which matters for clarity in fast-moving scenes; lower values reduce ghosting and motion blur. It’s different from how often the screen is redrawn (refresh rate) and from delays in the rest of the system (latency). The statement about the monitor updating its pixels directly describes this idea. The other options refer to booting the computer, a delay in detecting a device, or data transfer over USB, which are unrelated to how quickly a pixel changes color.
