I want to close the laptop lid and use 2 external displays.
When I select the display settings, I see the laptop screen and 1 external display.
Even though I have both external monitors attached (1 in HDMI port and 1 with an HDMI to USB adapter) a second external monitor is not detected.
When directly attached to the laptop's on board HDMI port, either external display works, but only 1 external display in addition to the laptop display is detected with the lid closed.
I also tried an HDMI splitter from the main laptop HDMI port. The signal is pushed to mirror both external monitors however only 1 external display is detected in the display settings along with laptop display (which is closed).
I have reviewed other related posts but have had no success.
Any help would be greatly appreciated
