6.5.1. Timing Parameters

Try these first

1. 1.

   What is a pixel clock?

   Hint

   Think about how quickly pixels are updated.

2. 2.

   What does refresh rate measure?

   Hint

   It's expressed in Hertz (Hz).

3. 3.

   What does a higher pixel clock speed result in?

   • Higher resolution and refresh rate
   • Lower color depth
   • Minimal impact on performance

   Hint

   Think about how clarity improves with speed.

4. 4.

   True or False: A refresh rate of 120Hz provides smoother motion than one of 60Hz.

   • True
   • False

   Hint

   Consider the difference in motion clarity in fast-paced scenes.

5. 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.

   Hint

   Remember the formula gives bandwidth in bits, convert to Gbps for final answer.

6. 6.

   Explain how increasing refresh rates beyond 120Hz affects the CPU and GPU workload in high-performance gaming systems.

   Hint

   Consider CPU/GPU capabilities to manage frames efficiently.
