Dear Fellows,

I am using lenovo yoga 3 pro with win 8.1 and lenovo thinkpad usb 3.0 dock, 4 days back i was able to view external display on my 24" led screen through usb 3.0 dock but now it is not able to display my extend/any display over the led screen.
I have updated each and any driver of the laptop including bios, IME, and displaylink 7.9M3 and lenovo driver for usb 3.0 released on 22 Oct 2015
It try to put the display over the led monitor but there is no sign just a minor light all over the screen actually it is the black screen but it showed that the screen is active but no display. All other function work like ethernet usb ports etc but sometimes it connects first time and sometime i have to attach the cable again and again to make other functions work properly
I have checked the usb 3.0 dock with another HP system with win 7, win 8.1, win 10 and it runs more smoothly than the yoga pro 3 with every function
Please help and advise
