EI342CKR Monitor Displaying "No Signal" On Port DP2

davidk4

I have 2 computers (1 Mac, 1 Dell Windows laptop) connected to 2 Acer EI342CKR monitors. The Mac is connected to DP1 on both monitors and the Dell to DP2 on both monitors. This configuration worked well for months. I use the under-monitor buttons to manually switch between DP inputs on the monitors. Recently the DP2 on my first monitor started displaying "No Signal" even when the cable is firmly connected in the monitor's DP2 and the Dell DP output.

I have tried swapping cables, swapping ports, swapping computers, but the DP2 connection keeps showing "No Signal".

I would appreciate any help in resolving this issue. Thanks in advance.

Some Dell laptops have an input select button you can press to switch between video inputs. Try Fn + F8 to switch to an external display.

In Windows 10, go to Settings > System > Display, then select Detect under Multiple Displays. You'll then be able to switch between screens. Also, you can press the Windows logo key + P to bring up the display list. Try selecting different display options for other attached monitors.
