Nvidia Shield TV

Hey all, just bought a Sony 65X9305 4K TV but i’am having bit of a problem with it, i have a few 3D movies on my Shield, when playing those 3D movies via kodi the TV fails to recognise the 3D movie and refuses to switch to 3D mode, even manually i cant activate 3D, 3D worked perfectly on my old 1080p TV.

Any ideas?
