From i.MX 6Solo/6DualLite Applications Processor Reference Manual, Rev. 4, 07/2018
188.8.131.52.6.1 Screen Refresh
• The refresh rate may vary within a predefined range. Within this range, the rate is
dynamically adjusted to the content update rate.
Reference manual mentioned that IPU will change display's refresh rate dynamically.
Let me confirm two things with you.
Q1. What is meaning of above description? I suppose if DMFC has not updated every frame, refresh rate will be down. is it right?
Q2. How do I know current refresh rate? does any register indicate us the current refresh rate?
