files on USB device shown as ._xxx.jpg

Question

To have a picture  show on my new LG OLED55B87LC I've connected an external USB 3.0 hard disk (formatted with MS-DOS FAT32 on my iMac) that I've filled with hundreds of pictures from my Fotos App. 

But when I open this drive on the TV the jpg pictures (numbered 1.jpg to 999.jpg) show up as ._1.jpg to ._999.jpg. When I scroll down at the end the list then the real jpg`s appear. So it looks like there's a copy of each file on this drive starting with  ._  ?? And all of them can't be shown on the TV - they look faulty ? 

I've tried out with another drive / USB stick - just the same problem. Does anyone experience the same problems ? Do USB devices have to be formatted in a special way ? Any idea how to solve this ? 

Ah - and beside this strange thing - is it normal that it last that long for the system of the TV to create all the thumbnail pictures to show on the TV ? When I scroll through a long list of pictures it lasts always a few seconds until the icons of the pictures really show the contents. This is really annoying because it makes the feature useless if I need several minutes to find a picture I'm searching for. Why is it that slow ? Is the USB connection only with 2.0 Standard ? Or is it a performance problem of WebOS ?

I have just copied 1500 24 megapixel images to a fast USB 3.0 USB flash drive SanDisk Cruzer Extreme 32GB, formatted as NTFS in Windows. My TV 49UH8507 did not create those files with weird filenames. However, TV is also slow at decoding images. It is equally slow regardless of the USB port I use. Namely, my TV has both USB 2.0 and 3.0 ports and it is always slow.

those are probably thumbnails  file metadata created by MacOSX, those are not visible in your computer because files with names beginning with a dot are considered "hidden" in all Unix-derived systems (Linux, MacOSX), due to FAT32 constraints it can't store thumbnails as resource forks (the MacOSX way), so it creates ._ files

    • Question: How can I change the screensaver pictures ???

      Hi, just bought a new LG OLED and pretty fast noticed that I`ve now chance to change the wallpapers ?!?
      Really pretty strange - even the smallest smartphone offers such a feature. The TV has enough USB interfaces - why is it not able to customize this by an own set of pictures ?
      Can`t be that big rocket science to implement this , especially for such an expensive device this should be a standard feature !!!

      Or did I  miss something in the settings of the TV ?
