I recently upgrade may OS from windows 7 to windows 10. Then I played my video files properly with "microsoft basic display adapter". But since I upgraded my driver to "AMD Mobility Radeon HD 5000 series" I have a problem with any video players. The files play only with sound under black screen. However when I rollback the driver to "microsoft basic" the problem solves. please help me because I want to use HDMI cable for watching my files and "microsoft basic" doesn't support it.
