Try this
Did you check the power cord and the monitor adapter connections?
➔ Check if the power cord is correctly connected to the multi tab and if the monitor adapter is accurately inserted.
Did you remove the connected cable and check the contact?
➔ Check if internal metal pins are bent or there are alien substances and if so, replace it with an authentic cable.
➔ If you use a cable out of the product specs, then it can cause screen blinking and no display and so on.
Did you reset the monitor setting?
➔ It can occur due to monitor power saving or auto off errors, thus reset the monitor to the factory setting.
