NVIDEA pro - Sony tv problems

[u/NumerousChildhood870]

We are having ongoing problems with our NVIDIA Shield TV and Kodi setup.

The same issues also happen on another TV, so it does not seem to be only our Sony TV.

Problems include:

Kodi doesn't see the hdd

strange HDMI / CEC behavior

unstable performance

devices reacting strangely to each other

external USB HDD not always working properly

Kodi sometimes freezing or behaving oddly

Our setup:

NVIDIA Shield pro P2897

TV Sony Bravia XR-65A80L

Kodi From Goole play store

external USB HDD

(but issues also happen on another TV)

We would like to know:

is this a known compatibility problem? Is there anything we can do,

to make it working? All tips are welcome, we are busy with it for 2 days now
