[LibreELEC 7.0.2 x82] Stuck with resolution of 800×600

I would like to apologize if I make any mistake, english isn’t my native language, this is my first post on this forum and its goddamn 2 AM where I live and I’ve trying (and failing) to fix this problem for about 4 hours straight

So I was using an old PC as a Media Center with an older Kodi version (Actually it was still called XBMC), I was using Windows XP because the PC is quite old and a friend of mine recommended not using Ubuntu at the time, for my surprise the PC could play 1080p files while the resolution of the screen was actually 1366/1360×768 (which as far as I know is the resolution of my TV, all my PCs recognize this one as the default), but I don’t know what happened but suddenly XBMC couldn’t download media info and after 6 month it just refused to open, so I thought It maybe would be worth trying an OS that is just made for Kodi, I’ve found out about LibreELEC and decided to try it out.

But I’ve found that its stuck on the resolution of 800×600, even worse is that the UI have some elements that are hidden in the border, its just weird, I’ve tried searching about but I haven’t find anything that could actually help (I’ve found someone with the same graphics card with the same issue on OpenELEC and the solution was to import the config of a Kodi that actually runs on 1366×768, but I haven’t mede the backup since I couldn’t event open XBMC on XP), there’s some thing about using a xrandr command in SSH, but I tried and it doesn’t work, even the addmode and NewMode

My Specs(don’t laugh):
-GeForce 6150SE nForce 430/integrated/SSE2
-OpenGL Version: 2.1.2 NVIDIA 304.131
-CPU: AMD Sempron™ Processor 140
-Memory 852MB

I know this is really shitty, but somehow with windows XP I could watch HD movies, and the only issue is that sometimes the movie would freeze for less than half a second and then continue, I would expect that with a OS made entirely of Kodi it would run even smoother than before
