Input signal not found

[Dark_Side_by_Q]

Hi all,
I have a problem that I can't solve in any way.

My 27' Curved Display has stop gettin video signal by any inputs, since some time - "Input signal not found" in any mode with any settings and inputs.
The monitor is displayed in the system like it works without any problem, DDC works and i can effectively change brightness or any other setting (with ClickMonitorDDC soft), win+p doin expand the desktop like there is no problem. *also there is no sound via headphone jack if i use it as an audio output device.
I connected it to two different laptops, used HDMI and DP wires but the result is the same - the system sees it, but the message "no input signal" is displayed on it. The wires were tested with other displays and everything is OK, as is the output from laptops to other displays.
I also tried factory resetting, but ther is no results. 

The last time I disconnected it from the laptop, and the next time I connected it, it cant found video signal.

So... can anyone tell me what the problem is?
Thanks in advance,
R.
