I tested with the refresh rate samples over here. Everything is played at 60Hz without prior frame rate conversion. Refresh rate/display mode APIs are not supported. I really lost my sensitivity for micro judder when playing 50fps @ 60Hz for example. But as I know now, it can be trained. Don't know whether this was a good idea though. If you like what you see, you should be happy .
Technologies like Sony’s ClearMotion are completely useless in this case as they don’t operate on the source video but the Android/OpenGL rendered output which is already wrong for 24/25fps @ 60Hz. A hardware FRC built into the SoC converting video to the display's refresh rate before rendering would probably be a good solution.
I just played around a bit with my Android TV Lollipop (5.1.1) based Sony TV with respect to refresh rate handling and smooth media playback...
Even with 'Adjust display refresh rate' being disabled ('Off'), 24p and 25i/50p look pretty smooth to my eyes. I assume that the hardware performs some frame rate conversion?
After enabling 'Adjust display refresh rate', no change in refresh rate seems to take place when I play different media. I also can't find any evidence inside the log that a change happens. 'System Information' always says that it is at 60Hz. At least PAL content should not play smoothly at 60Hz!?
I should be happy that everything plays smoothly. It would be interesting to know how this is achieved though. Or did I completely lose my sensitivity?
