Originally, stable widi connection can be built between the equipment a few months ago.
However, during this month, it failed and only black screen with cursor moving was shown then dropped after 10s.
I studied a lot from this forum and figured it out it may due to the display card software issue.
I uninstalled and reinstalled it with different version: Asus factory display card software, Intel Bay Trail 15.33.30.3958.
Both can establish a stable connection for the first time. However, the black screen phenomenon happens again for the onward trials of connection.
Can anyone render some advices on the situation?
Thanks!
