Dual Monitor (Extended Display) Not Working

[WaNic]

I've been trying to get an extended desktop to work with this notebook, but nothing seems to be working properly.  When I connect the second monitor and set the displays to "duplicate these displays" everything works well.  However, as soon I try to set the displays to "extend these displays" both screens, the built-in and external monitor, start blinking on and off.  All of the latest Windows 10 and HP updates are installed including the video/graphics driver but nothing seems to allow me to setup the extended displays. 

I've been told that the video/graphic drivers on HP have issues with Windows 10 but I've checked and everything here is up to date. 

Need dual montiors to work properly.

Any help and a solution would be most appreciated.

Good Day. A warm welcome to the HP community. I reviewed the case regarding issues with the computer. I will be delighted to assist you here.

I would like to ask you a few questions.

How are the display's connected?

Is it using the HDMI port?

Any other error messages when you switch to extend?

Keep me posted. 🙂

Hello Barachiel,

I trust that these answers prove helpful.

How are the display's connected?

- Direct cable from notebook to monitopr - HDMI

Is it using the HDMI port?

 - Yes

Any other error messages when you switch to extend?

 - No error messages; just the on-off-on-off cycling of the displays on both the notebopok and the external HDMI connected doisplay monitor.

Thankls in advance...

Thanks for the response.

Goto search, and then search for windows updates, and run the windows updates.

Once done, re-start the computer and check if it work's.

If it doesn't, then open device manager, track down the graphics driver, then right click on it and click on update.

Let me know. 🙂
