My first and only one post I hope
Same HDMI problem here
Notebook Samsung 3500EM, windows 10 education, with intel HD620 graphics and TV LG 47LW579S-ZD, smart 3D. This LG TV worked like a charm with Toshiba Satellite L750, windows 7, in all display modes. Allmost one month I am installing and uninstalling graphic drivers. Same laptop is working with Denver 55" UHD TV, but not working with Samsung 46"...
I will attach some screen shots when HDMI connected and when not. Sound is going all time trough HDMI connection, no picture at all. Last screen shot was made with HDMI connected, sisplay set as extended, which is shown on screen shot, but no at TV.
I understand you are having the same problem with the Intel® Graphics HD620.
In order to provide you with more accurate information and a proper solution, it is my recommendation for you to open a new thread explaining your situation since we can not assist more than one issue per threat.
I really apologize for any type of inconvenience this might cause and thank you in advance for your patience.
