Windows 10: HDMI monitor not comunicating with computer after update for Windows 10

I too woke up this morning with my display non-functioning. I had shut off the monitor before retiring for the night but left the computer on to finish some work by itself. Some time after the computer finished its work the Windows 10 update came in and rebooted the computer after completing the update. The monitor was off of course and when I turned my monitor back on this morning I had no response and communications from the computer via the HDMI port to the monitor. After reading the many reports in this forum I switched to the VGA port to regain use of the system and then rebooted with the HDMI activated and everything came up fine with my preferred HDMI port working. Thanks to whomever suggested re-booting as a fix to the issue.

Issue:

• One morning after regular updates my graphics card stopped sending signals to HDMI monitors that are bellow the resolution of 4k. The monitors, just shows no signal, when you uninstall the drivers sometimes, like once in 4 times it will catch
  the monitor, but if you restart the PC you will again get no signal. The monitors works perfectly with my laptop on HDMI. 3 Of the monitors are fresh from the box. The HDMI port works perfectly with my 4k TV. Tried switching 7 HDMI cables total. Reinstalled
  windows twice, video drivers several times. Currently using a display port for one of the monitors.

 

HDMI Port Stopped Working


I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?
