Most devices support FAT32 and exFAT as the major OSes( Windows,Linux,MacOSX) support them almost as their native filesystem. Its strange to see LG TV support a proprietary and which is badly/not fully supported on all OSes: NTFS. This filesystem (NTFS) should be the last to support on any other device thats not a Windows machine.
My problem: I use a macos and can not write on NTFS devices. If I wish to view a 4K movie (64GB) , I have to pay an additional 20-30$ for a software that allows my mac to write/format NTFS files to a usb stick. The free-open-source software ntfs-3g its not good enough because it takes about 3hours to write a 4k movie (64GB) on a USB3.0 (UltraFit).
Great TV LG, but thanks a lot (sarcastically) for taking from me more money and time to write my wedding on a USB3.0 so that I can view it on the TV.
