    W10 not detecting 2 monitors, so cannot extend the screen?


    Hello everyone,

    Due to the Coronavirus, I'm working from home indefinitely now. I would like to work using two monitor screens as I do in the office, but I'm unable to work out how.

    I have a laptop and 2 monitors. I have only 1 HDMI port in my laptop, so bought a HDMI splitter and have separate HDMI leads from the splitter into each monitor.

    It works in the sense that I am typing on my laptop now, and I can see my two monitors with the same display as my laptop currently. The issue comes when I want to extend the screens (i.e. close my laptop, and use two screens only. Left monitor being primary, and right monitor being secondary).

    When I try to extend screens, it keeps my laptop screen as Screen 1, and then classes both of my monitors as screen 2. There is no screen 3, even though I am technically using 3 screens (laptop and 2 monitors).

    I've spent hours trying to work this now; is anybody able to advise how I can work use one monitor as primary, one as secondary with screen extended, and the laptop screen effectively being off?

    I've been into device manager, and ensured my display adaptors are up to date as well.

    Thank you so much in advance W10 not detecting 2 monitors, so cannot extend the screen? :)

  3. extending monitors

    Hello,

    I hope I can help you today

    solote allow two monitors but here I leave this possible solution

    Step 1

    Connect a monitor to the normal video card, using the necessary cable (DVI, VGA or HDMI). This will be the main screen, so place it directly in front of your computer's cabinet.

    Step 2

    Connect the second monitor to the alternative port of the video card, and then restart the computer. The PC will automatically detect the second monitor.

    Step 3

    Go to the "Show options" window by right clicking on the desktop, then select the "Properties" option. From there, click on the second monitor (which will appear in the drop-down menu), and then activate the "Extend my desktop on this screen" checkbox.

    Step 4

    Connect the third monitor to your original video card (if it has three outputs) or to another video card, and then restart the computer one more time.

    Step 5

    Go to the "Show options" window by right clicking on the desktop, then select the "Properties" option. From there, click on the third monitor (which will appear in the drop-down menu), and then activate the "Extend my desktop to this screen" checkbox

    regards...

    W10 not detecting 2 monitors, so cannot extend the screen?

    Extending 2 Dell Monitors

    Hello!

    I am very technologically challenged, and I am trying to EXTEND (not mirror) my 2 desktop Dell monitors.

    My computer only has one vga port, and my monitors have hdmi cables.

    I bought a uGreen hdmi female to vga male adapter but I still can't figure it out.

    I am able to mirror them but not extend them as i'm wanting to do for my work.

    I looked in the display settings area, and it only shows one monitor, and it won't detect the 2nd one at all.

    If anyone could be so kind to do a STEP BY STEP instruction on how to set this up, i'd greatly appreciate it!!
