The hdmi for the extended monitor stopped working. The proposed solution is to update the thunderbold driver but the driver is not there. See link below
What should I do? Is there a fix as I need the HDMI port working. I'm very surprised to see this issue for such an expensive laptop. Please let me know.
Thank you in advance

You should be able to download the Thunderbolt driver here (http://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-P-SERIES-LAPTOPS/THINKPAD-P...

My HDMI external monitor suddenly stopped working last week, after no problems for 15 months, since the time I purchased the P50. I'm running Windows 10 and have video card NVIDIA Quado M10000M. I have searched this forum and have done all of the following that I found from other posts:
1) Uninstall and reinstall NVIDIA drivers
2) Reinstall Intel Management Engine Firmware
3) Reinstall Thunderbolt software (using link in this post)
4) Installed Thunderbolt firmware from here https://support.lenovo.com/us/en/solutions/sf16-t0051
When installing the NVIDIA drivers I do see the message others have reported for 2 of the files "Did not install...because it is not better than the current drivers (kil20202.inf and nvlt.inf).
After each install I tested my external monitor and nothing has helped. I also ran Lenovo diagnostics "LiteGUI" for the video card initially, and after each software install, and get the same result regardless. Everything passes except video memory:
"Video memory test not applicable. Try to (re)install the official display driver that supports your product."
"Direct 3D commands could not be sent"
"OpenCl commands could not be sent"
Ocasionally after restarting following an install I have the message "Video Memory Management Internal" error and stop code Video_TDR_Failure. When that happens I reinstalled NVIDIA drivers and restarted and did not get the message the next time.
Is there anything else I can try?
