HP Laptop Does Not Recognize Monitor Using HDMI-HDMI Connection

[huey5000]

I just got an Acer 27" monitor with a HDMI connection.  Tried to connect to my HP Spectre x360 Convertible using Windows 10 with an HDMI commection; the laptop does detect the monitor ( I can tell in Windows settings) but the monitor will not display video.

I used a lower series HP laptop with Windows 10 and connected to the new monitor with the same HDMI cable (Insignia) and had no issues - monitor and HDMI cable work fine.  I also used the same cable to connect my HP Spectre to an older series Acer 24 " monitor - works fine.

Checked to make sure all HP and Windows drivers are up to date - they are.

Is there anything else I should be checking here?  Thanks in advance.

HP Spectre 360 External monitor via HDMI not working - solved for me. 

My touchpad hasn't worked for 3 updates now, and I've troubleshot it unsuccessfully for waaaay too much time.

I've simply settled in with using an external mouse, not wasting any more time on it.

Recently the HP Spectre has stopped connecting to the external 27" monitor.

It didn't recognize either the HDMI connection (The cable and monitor work when connected to another laptop)
OR
my USB-C to HDMI adapter (that also works on another laptop.

Troubleshot it with all of the suggestions here on the forum. No dice.

The USB-C not working was the clue.

Here's what fixed the monitor problem for me.

It's the only change I made in this iteration of troubleshooting - and the monitor simply flashed back to life.

In device manager : View | Show Hidden devices

Expand Mice and Other Pointing Devices

Disable and uninstall the non-working Synaptics touchpad driver. It probably has a yellow warning Icon on it that it's not functioning correctly.

Apparently the bad Synaptics Touchpad driver was hijacking something.
