4k Slow screen refresh

  • The device has no GPU acceleration, 4k resolution refresh slowly, * Is there a good solution

Which board are you using?

Post your disp_flush, please.

4K is a very high resolution to handle with software alone (not even 2D acceleration). When MouriNaruto was testing the revamped Windows driver, the maximum resolution with a stable frame rate was 1080p.

  • I made my own board,USE Hi3536 chip

but 1080p Refresh is also slow
