VLC change windows 7 color scheme to basic

VLC change windows 7 color scheme to basic.......

Also cause VLC player display black screen video, with smooth audio playing.

  1. Re-install VLC player portable, then original VLC player,  resetting VLC's preferences  Choose "Delete preferences and cache"  (no avail) (some thread suggested trying old version instead)
  2. Graphics card driver & direct X update (no problem shown on original driver, so )
  3. changing the output module of vlc player to open gl,   in preferences>video>output module there first check advanced options  (no avail)
  4. From the menu > 'Tools' > 'Preferences' > 'Video' > 'Output' > switched to 'Windows GDI video output' > press 'Save' button. (This works for me)
