I wonder if the software (firmware) in the TV supports it. If not, there's nothing you can do on the hard disk to see them. If it's not in the manual, only LG knows that. So you picked the right forum, but I doubt if you will get a definite answer.
I have an external hard drive connected to my LG smart tv everything works fine, I was just going to see if anyone knows how to add an icon/thumbnail to the movie files so the movie covers will be displayed when browsing the films on the external HDD.
Is there a certain extension needed to be added to the image i wish to attach to the movie file?
Any help would be appreciated greatly.
