Why Won T My Monitor Recognize Hdmi. Having same issues as everyone else running 2 monitors through Lenovo ThinkPad Thunderbolt 3 Dock was working fine as of yesterday automatic update done and now X1 does not recognize the additional monitors. I would try installingupdating the HDMI driver for your graphics chip and see if that helps.
You can also try disabling any power saving features the monitor has see manual and enabling the show startup logo for the bios if not already enabled. I recently updated my windows 10. This will resolve any problems you might be experiencing due to your cable.
I purchased an Acer Aspire TC-885-UA92 desktop recently and am trying to add my secondary Dell E2416H by way of DP to HDMI cable and the desktop wont recognize it - Ive tested the monitor by connecting it to my laptop via HDMI and VGA and it works fine.
