My laptop was working fine until one morning it decided it would not connect to/ recognize any HDMI outputs. I checked my cables and HDMIs with other laptops which worked fine. For some reason my laptop refuses to identify the external monitors. I tried updating drivers, changing the screen to "Extend" mode and even performing a factor reset to no avail. Please help.

I presume you are using a USB-C 3 to HDMI converter dongle.
I have found these sensivtive to :the following
1. The actual plug in sequence..... I found I needed to shutdown and restart computer and monitor when tryimng to connect. Then plug in dongle to computer then plug monitor HDMI cable into the dongle. Then start the intel grpahics control software and set thre external monitor as you want it . Sometimes takes multiple trys to get the external monityotr to be recognised by the graphics control software
2. the cables and dongles used. ... I t appears easy to not get good connections due to poorly inseted connections or damaged pins in the connectors across the multiple connectors

Thanks for your response. I considered that might be the option. However.
This is leading me to believe that it might be a problem with either Lenovo or with a recent Windows update.
