Windows 10: Setting up a projector as an extended display

I am trying to connect my projector as an extended display to my personal computer. I have a VGA cord running from my PC to my projector, then out to my monitor. Windows is only recognizing one display. How can they be set up to show 2 separate displays? NOTE: In my display settings it does not detect a second monitor or display.

:)

 

One external display (projector), 5 shown in Display Settings.


I've tried searching the forums but haven't been able to find anyone with the same problem, so if a thread already exists and I just failed at finding it please point me in that direction.

I have a Lenovo L440 laptop running Windows 10 1607, it has an Intel HD Graphics 4600 video card which lists the last available driver as 15.40 from the 23rd of June 2017.

It has an issue where I connect a projector and I get the flashing display to indicate another display was detected and connected, but nothing displays out to the projector (which is set to use the correct input). I press the shortcut to duplicate the displays and nothing happens. I go in to display settings, and see 5 displays (give or take depending on the laptop) despite only one external one being connected. If I tell it to use displays 1 and 2, nothing, so disable display 2. Then tell it to use displays 1 and 3, nothing, so disable display 3. Repeat this process enough time, it'll eventually come to the display the projector is configured as (sometimes having to add additional displays to what was being shown originally).

It's OK for me to do this as I'm the IT guy, but it's not OK for the staff to do this.

Here is a sample screenshot from another machine with the same problem. Only one external screen (2 in total) is connected.





Some machines with more up to date video cards such as Intel 540's have had driver updates putting them to 15.46, and the problem is thus resolved. It's back to behaving as expected for displayed screens and sending output to the right spot. But the laptop in question won't take those drivers.

Does anybody have any suggestions for other things I may try to resolve this?

 

Extended Display Settings

I was going through the display settings in my laptop to connect to a projector. After I selected 'Extend to all screens', I accidently selected 'keep changes' instead of 'revert'. Now, I'm not able to select the display settings options. I really could
use some help regarding this issue.

Thank You

 

no audio on extended display

We would like to know more information from your end to know what is the next possible step that we can offer for you to resolve your issue.

• Were you able to get an audio on your extended display before? Or is this the first time that you will set up an extended display with your computer?
• Aside from the HDMI cable, have you tried using VGA cable instead to connect to your extended display?
• Can you verify if you have any audio on your speakers if you are not connected to the extended display?

We look forward to your reply.
