The monitor "hangs" when I turn on the power. It only displays the Predator logo and the nvicia G-Sync logo in the bottom right corner. The buttons on the monitor are non-responsive and even if I turn the monitor off by using the "ON/OFF" switch next to the power cable, it still only shows these logos. I've tried to disconnect it completely from power, and let it stay without any power for 1-2 hours, but the same thing happens.
There was a strange "beeping" sound coming from the monitor yesterday. I switched it off and then back on with no problem.
I took a small video with the sound: https://vid.me/W68Hx
Can anyone please help me with this? The beeping sound is gone, but I can not get the monitor to show anything other than the predator logo. It's like it is completely frozen....
