What does refresh rate measure?
Show hintHide hint
It's expressed in Hertz (Hz).
3Question 3.
What does a higher pixel clock speed result in?
- Higher resolution and refresh rate
- Lower color depth
- Minimal impact on performance
Show hintHide hint
Think about how clarity improves with speed.
4Question 4.
True or False: A refresh rate of 120Hz provides smoother motion than one of 60Hz.
- True
- False
Show hintHide hint
Consider the difference in motion clarity in fast-paced scenes.
Question 5.
Given a 4K display (3840x2160) with a 60Hz refresh rate, calculate the required bandwidth in Gbps assuming 24-bit color depth. Discuss the implications of bandwidth limitations.
Show hintHide hint
Remember the formula gives bandwidth in bits, convert to Gbps for final answer.
Question 6.
