VobSub problem with Samsung smart tv

So i recently tried to use VobSub subtitles instead of.srt for movies on my Samsung tv (because it shows a white text with no outline or any kind of styles and hard to read)

and whatever i do the TV just don't respect the positioning or outline color only the size (it shows a grey white outline and subtitles at bottom of the screen)

I use subtitle edit to adjust styles and export .ass file
Then with EasySup i convert it to PGS
And with Bdsup2sub i convert it to VobSub

Other notes:
1-my TV don't support PGS or .ass with styles
2-i tried to import VobSub directly from subtitle edit showed same thing (+lower quality)
3-also tried to use .srt file directly on EasySup and adjust styles from there
4- tried a VobSub subtitles that was already imbedded in a video "didn't make it"
5- the subtitles work fine on my PC and every other device i use

So if there is anything i could do about this i would appreciate any help, and thank you all 🙏

How old is your Samsung TV? I have a 4 year old Samsung and I have no problem with displaying .SRT subtitles. I can choose the size, color, font, background., boarder. However, I cannot display VOBSUB subtitles. My TV will only display the first VOB subtitle line. After that, nothing, so I am forced to use SRT subtitles. What does your manual say about subtitles?
