There is a economic solution for test HDMI Hz out? maybe adb comand or tool?

Accurate refresh rate readings can be taken only from HDMI output. So, an external device has to be used.

you sure? a year? i never found amlogic box/player mentioned 23,976(5) support.

Yes, it is almost a year. First firmware with 23.976Hz mode for Minix X8-H was released on 7/11/14. It has been improved upon since. There was a "slow-motion" bug present in beta 9 firmware. Amlogic had to come up with an entirely new SDK to correct that bug. Adaptive refresh rate was first introduced for Kodi and later at system level in firmware 003 in Feb 2015. So, yeah Minix boxes have had 23.976Hz mode for a long time and they are probably the only Android boxes that have dynamic refresh rate switching at system level.

Currently, Amlogic has some problem on the compatibility between 23.976 and HD audio Passthrough. You can only choose one, 23.976 or HD audio passthrough.
This is a complicated problem that can't be solved with software. When they released their 64-bit chipset, this will be solved.

Yes, HD audio passthrough and 23.976Hz mode has some AVR compatibility issues on Vidon Kodi/XBMC.

AFAIK, Amlogic released 23.976 feature in the latest SDK update, which is also the latest SDK of Minix X8-H Plus, v005. I've never heard Amlogic could support 23.976Hz before.

It is not true. As mentioned above, Minix boxes have had 23.976Hz mode for a long time. If you want, you can check Minix forums.

Just want to confirm, you HAVE to use vidon xbmc and pay the yearly subscription to have hd audio passthrough on the minix x8h or can you just load up the latest kodi from the official website and it will work?
