Display blink all time

Have u tried any troubleshooting? If not, u likely can't fix it yourself.

First, u must isolate the problem to the display or the device it is connected to.

That requires plugging each into different devices and trying different ports on each device.

If u can do that and post the results u may get an answer.

@debasishro51302 what is blinking? The power LED? The screen? What have you already checked? Have you connected the monitor to a different computer? Did it continue to blink? We need more details to try to help you fix this monitor.
