|The 42UB820V is made by LG not Samsung. How closely have you read the manual? I just had a quick look at the USB section, here's a few highlights:|
- If the USB storage device has a built-in auto recognition program or uses its own driver, it may not work.
- Some USB storage devices may not work or may work incorrectly.
- Use only USB storage devices formatted with the Windows FAT32 or NTFS file system.
- It is recommended that you use USB Flash Drives of 32 GB or less and USB HDD of 2 TB or less.
