files on USB device shown as ._xxx.jpg

[rologoetz]

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),

Had a long discussion in LG support chat a few days ago.

Basic message : 

The TV System (WebOS?) doesn't support more than 999 files (pictures, folders, whatever) !! What ??🤔😮

Can't tell how irritated I was by this statement ! A operation system that doesn´t support more than 999 files on a volume ???

Even if I format the drive to NTFS - same restriction. 

Asking for the reason I got as feedback "you have a TV which is for moving pictures (movies, series, TV shows...) and not as for presentation of pictures. Generally customers don`t have 1000 movies on their hard drive" ... !!

Asking in return what about music files ?

Answer "same limitation" ?!!

So Im pretty irritated about the purpose of the music + picture apps in WebOS or the Gallery app ... . Okay - then I asked "...so I've to use an Apple TV or a NAS server ? And there's no such limitation of <999 files ?".

Answer "no, same limitation" !

Conclusion : 

the  LG TV I've bought promissed high connectivity (4 x HDMI, 3 x USB, Ethernet) - but there's no chance to use it central media viewer without additional hardware.  And the database to use is limited to 999 files. 

I`ve 40000 pictures on my iMac, another 80000 music files (from my big CD collection) - and there's no way to handle this via WebOS ?  My iMac 27" is from 2010 still doing a pretty good job - and an expensive Multimedia TV (!?!) from 2018 can't handle this ? 

And this despite the WebOS has several Apps that look so promising - really, really disappointing. 

Sorry LG, but if there would`t be this really good OLED display I wouldn't have bought your TV. Guess other brands (using your OLEDs) have a better OS. WebOS is a nice toolbox - but none of the tools are programmed to the end. Or can anyone tell me the real purpose of the gallery app (despite its nice for the showroom of the sellers to show some 4K pictures - but only a few, more is not working ) ? Or a pictures app where  you can't search and that doesn't support folders ? Same for the music app where you can't really sort.

What you could do is instal Plex on you Mac and the Plex app on you TV. This way you can play a lot of stuff from you computer. And it looks nicer.
