Crossover 404KS - Problem

Got my new monitor from Korea today.

When I connect power brick without having it connected to monitor the little green light on the brick will light up and everything looks good.

However when I connect it to the monitor the green light will immediately turn off and the monitor is not responding in any way,not turning on at all.

Also I noticed that my radio in the other room has some weird interference as soon as I connect the power brick to the monitor.

Power brick broken? Monitor broken?

What´s ur thoughts?

Try a different display port cables. You may have a 20 pin cable and you need a 19 pin cable

even without any display cables connected (HDMI, DP, VGA etc) connected it still doesnt respond or power on
