    Add 3rd monitor Wndows 10

    I'm trying to add a 3rd monitor to my PC but it appears one of the hdmi ports on my pc is not active. I have 2 hdmi ports, both monitors work fine when connected to one of the ports which suggests both monitors are ok, but neither are detected when connected to the other port. Any ideas? Thanks.

    Is there any settings in the BIOS or UEFI for this port? May need enabling.

    So normally when you boot up your pc there maybe an option to go into UEFI. Maybe one of the F keys on the top or delete. Would try F8, F10 or F12...but as I say would normally tell you.

    Followed two methods to access the advanced start up which should allow access to uefi setting but there's no option for uefi under advanced settings. Could I buy an hdmi splitter and connect both monitors to the one active hdmi port?

    Hmm not sure. I'm not convinced that will work.
    What make and model is your motherboard mate?

    Have you tried to access the UEFI from a cold start or did you just do a reboot?

    What version of Windows are you on?

    Looking on Lenovo site it may be F1 or F2 you need to be pressing but you should see something pop up saying to press a key to enter the BIOS or UEFI.

    Or try Fn +F2

    I'm using Windows 10. I did just reboot, I'll shut down and try F1 and F2 now.

    I shut down and started from cold, there's no option during start up to enter uefi or bios, it just boots to my desktop. F1 and F2 had no effect, pressing F1 once the computer has booted loads a general Windows 10 webpage.
