Question: are 4k tvs 3d compatible?
Answer: Only if The 4k TV supports 3D and so does the Blu-ray player and both HDMI cables are also 3D compatible. Most 4K TV's don't now days except for the majority of DLP,LCOS and LCD front projectors. ... 4k blue ray does not support 3D as far as I can tell so not 4k 3D movies on disc.
