I wish i knew what i did ...........
If you remove nvidia 720, ehd is working.
Maybe an nvidia compatibility issue with ehd ?
All i know is i have no picture.
This is the case with bm2lts 2.90 , 2.94.4 and 2.88 .
The best/stable version of bm2lts for me is 2.88 but i wish i did not trash 2.87 which also worked.
I will try to reinstall 2.88.
