Half SBS image displayed Left/right instead of up/down

[ovidiubuligan]

Hello ,
I bought an lg 3d smart tv (55LA660) and it is a passive 3d display .I am using it as a monitor when playing movies from my pc.
I have an 3d mkv ecoded with HSBS and it displays side by side like in the image:

If i set my tv to use left/right 3d mode then it works fine (also the subtitles blend nicely)
The problem is that I am loosing horizontal resolution .

Key aspect about HSBS is : Half SBS=960×1080 per eye

With passive 3d tech it by design to loose vertical resolution and preserve horizontal.
Is there any method to display the two left/right streams up and down (loosing only vertical resolution), also moving the two left/right subtitles up , respectively down?

I have also tried the plugin http://sourceforge.net/projects/vlcinterlacedhs/ but that only works with vlc 2.0.5 and ignores subtitles.
( also I think up/down split should be made by default because there is no other 3d tech out there that prefers it left/right)
