I have an issue appeared after upgrading Windows from 8.1 to 10.
I have Lenovo Z50-70 (Intel display adapter and NVidia GeForce 840M).
Issue is having no rsponse when connecting External Display using HDMI this issue came out after upgrading to Windows 10 and not exist when connecting using VGA .
So, any solution for such an issue.
Is your cable high speed? If not, can you check connecting it through a high speed hdmi cable to see if it works?

Your feedback helps us improve!Hi rany,
Welcome to the community,
have you tried updating graphics drivers?
You probably need to do some sort of cold reboot. Win 10 boots from cached archive for speed and it may not be right. Try doing a RESTART at shutdown as it takes longer to come up I am guessing it reloads everything.
Otherwise is a driver issue.

i'm glad i could help :). i had the same problem and it was soo frustrating =p
All cables should be 1.4 by now or better. There was the odd 1.3 especially in very long lengths of 25 -50ft but everything I have seen for years are 1.4 at least. I know in my z70 you have to push in that extra 1/8" for it to mate otherewise nothing happens. I was puzzled for a while until I realized that.
