The external monitor I have:
Samsung C49RG90 49-inch Super Ultrawide Curved Gaming Dual WQHD 1440p Monitor
I am connecting the monitor to the laptop using a HDMI cable. The monitor appears in the Device Manager listed as a Generic PnP Monitor, the laptop display is also displayed as a Generic PnP Monitor.
If I open the Display Settings I can see both monitors are present and the second monitor is shown as a rectangle presentation that is scaled according to its size compared to the laptop with 1 shown in the laptop representation and 2 in the second display. However nothing appears on the second display and it keeps flickering and flashing up HDMI on the display. If I click the identify button a 1 is displayed on the laptop but nothing not the second display.
I know this monitor works and so does the cable because I have an iMAC on the same desk and if I connect the monitor to the iMAC using the same cable it works, but not on this laptop, what could be the issue?
