What Kodi file do I have to install for my Sony Bravia TV 4K?

Hi, I use Sony Bravia TV 4K 65″ (Sony KD-65X8509C) and I watch above all UHD (4K) videos. I have my files inside an esternal hard disk connected by USB cable to the TV.
There are many Kodi files x32 and x64, etc. … it is a jungle for me. Wink
Can you tell me what precise file (the latest version) do I have to download for my Sony Bravia 65″ TV?
Thanks a lot!
