To be specific a HIGH SPEED HDMI cable is needed for 3d support, previously called a HDMI catagory 2. Officially there is no such thing as a HDMI 1.3, 1.4 etc cable. HDMI 1.4 standards did define two new types of HDMI cables (one the one with ethernet and one with different size connection meant for autos), but neither of the two new types is meant for use with this TV. To try and stop confusion the standards say cables should NOT be identified ad 1.1, 1.2, 1.3, 1.4 etc.
