Intel WiDi problem with Dell Inspiron after Windows10 upgrade- black screen

I am having problem connecting  to my LG smart TV ( model no: 60LB7100). Before Microsoft 10 upgrade it was connecting without problem. However, all I am getting is black screen now. My laptop came with Windows 8.1 and it is only 6 months old. I tried to update all the drivers using Windows update, Dell's and Intel's websites but it did not solve the problem. Here is what I have:

Dell inspiron 5548, i5 processor,8GB RAM, 64 bit

intel hd graphics 5500 driver date 8/31/2015 version 10.18.15.4281

network adaper intel dual band wireless AC 3160 11/3/2015 version 18.30.9

intel widi 6.0.57.0

Thanks in advance,
