After a windows 10 update, the HDMI connection stopped working. I know that the HDMI cable and screen are working fine.
I have the Intel VGA Driver for Windows 10 (64 bit) - Lenovo M30-70 version 10.18.15.4240 driver installed.

Thanks for using the Lenovo forums.
Is this the most recent Windows update? It seems that your device has not yet been tested for this as of https://support.lenovo.com/de/en/solutions/ht503655 this posting.
Try to update your Chipset driver from the support page.
Make sure to reboot after an update.
Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.
(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal
If the above does not work, then try to revert back to a version before the udpate, see if the issue persists.
Hope this helps, let us know how you get on.

I was using Skype the other day and wanted to share my screen. I was astonished to find that I am able to share my second screen (extended) - even though my HDMI port is still not able to output to the second monitor !!

It seems that the latest update for the Graphics drivers from Intel that Windows installs are not verfied on the M30 and the HDMI fails.
Go to the Lenovo support site and download the one from there. When you install it will tell you that the driver is older than your current one. Install anyway and after reboot HDMI should work again.
Everytime Windows 10 updates it looks for updated drivers and installs. Windows doesnt ask you it just updates without telling you Unfortunately I have to do this everytime Windows 10 updates but it solves the HDMI issue. So even if you think you have the old driver reinstall from the support site to be sure.
