According to this LG link the TV does indeed support NTFS format drives. http://www.lg.com/hk_en/support/product-help/CT20136005-1436499459857-connecting-external-devices
But it also says:
“It is recommended that you use a USB Flash Drive of 32 GB or less or a USB HDD of 2 TB or less.”
and
"It is recommended that you use a USB hub or hard disk drive with a power supply.
(If the power supplied is not sufficient, the USB storage device may not be detected properly.) "
