BEST SETTINGS FOR 4K UPSCALING ON KODI

Hi Guys,

I have HTPC with NvidiaGTX970 using KODI. I have a question and need your guidance. Setting on KODI for Up-scaling. De-interlacing does it has to be ON or Auto or Off?. On Up-scaling should we select DBVA or Lancosz or? Which is the best for 4K upscaling? Let me know. Thanks.
