I am unable to extend desktop to a new second monitor.

HP Recommended
HP Slimline Desktop 410-010
Microsoft Windows 10 (64-bit)

I am unable to extend desktop to a new second monitor.  

I have HP Slimline Desktop 410-010 with Intel (R) HD Graphics 4400

The second monitor displays same as main monitor - both display the desktop.

The Intel HD Graphics Control Panel "Multiple Displays" view only shows Single Display.  Control Panel Display shows only one monitor recognized. Will not Detect or Identify the second one though the second on is showing Desktop like the main monitor.

I have tried updating the Intel (R) HD Graphics 4400 in Device Manager but it says up to date.

Can you help?

Graphics capabilities on the Intel 4th generation Core i3-4170 are OK.  It supports up to three independent displays: HDMI, DVI, Display Port, VGA (via Lynx Point).

I only see two choices for display on the case, however - VGA and HDMI.  How are the monitors connected?

OK, thank you.  That explains why both monitors are showing the same image.  A splitter is doing the job intended when both monitors show the same image.  In order for Windows to identify the second monitor, it needs to be connected to an indepentdant graphics port on the PC.

Here is the support page for the  HP Slimline 410-010 Desktop

https://support.hp.com/us-en/product/hp-slimline-410-000-desktop-pc-series/8499658/model/8524424/doc...

Scroll down to the topic with the heading of "Back I/O ports".  Click on that and it will show a picture of the output ports.  #3 is VGA and #4 is HDMI.  In order to connect the second monitor so that Windows can identify it, the second monitor needs to be connected to the HDMI output.  If one of your two monitors has a HDMI port, too, then it will be a simple thing of getting a HDMI cable to connect it.  Otherwise if both monitors are VGA only, an adapter similar to this should fix the problem
