Aspect Ratio problems

[Montino]

Hi All....
I use SS-IPTV player on an LG TV running Webos 5.2.0: I can't change the display format (16:9, 4:3, original, zoom, etc.): I need it because 
some channels are shown with the zoom (so a part of the image is not visible) or in 4:3, (leaving huge black bands on the sides), while I
I would like to set them to 16:9, which I actually do... but it has no effect. I also tryed to use other iptv players for testing, but I have 
the same problem... I couldn't solve ....
Maybe it's a not very compatible version of webos? (I use the same ss-iptv on another old tv with webos 3.8.0 and everything works perfectly, 
(indeed, in that case I don't even need to change aspect ratio because all channels are perfectly displayed in 16:9)
has anyone had the same problem or know how to fix it? or the attempts I could make?
Thank you!

@Montino Have you reported this to your country LG support directly? This is only a peer-to-peer enthusiasts forum, and has no direct reporting to LG itself.

It may be a buggy app/player, so they might not be aware.
