    Extended monitors keep reverting to mirroring each other.


    I have 3 monitors. 1Laptop lenovo t490 windows 102 & 3 Dell P1914SI was able to initially set up extended monitors A-B-CWhen I restarted my laptop the two dell screens extend from the laptop, but now mirror each other. A-B-BMy laptop no longer recognises that there are 3 screens in the settings. but still mirrors screens 2&3. I have tried disconnecting, reconnecting, switching cables, rebooting etc etc but I can not seem to get the laptop to recognise 2&3 as separate anymore.

    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!!

    how to mirror 2nd monitor to 3rd monitor

    I was using win 7 with 3 monitors, extending desktop to second monitor and mirroring the second on the third monitor. I don't see how to do this in Win 10. Option not available?

Each display works independently of the other - there is not option for this in display settings - multiple displays. It was set up this way before a vacation, so I know its possible! Thanks :)...
