I have a 2017 model LG OLED TV with WebOS. I've tried using DLNA, which technically works, but practically is no use to me. I load captions and titles onto my photos when I edit them. DLNA only serves out these titles, not the filenames. So I can't view my photos in order. I'm not going to go back over thousands of photos and add 001, 002, 003, etc to each title. There is no sort by filename functionality that I can find on the WebOS app when viewing by DLNA. So my networked Smart TV isn't so smart after-all. To view my files in order, I have to copy them onto a USB stick and carry it to the TV, then pull the TV away from the wall so I can plug it in. NOT HAPPY!. I like the suggestion of allowing a file manager style app that can view files on NAS, NFS, or Windows Shares. This would be a SMART thing to do.
