The video-card on your computer is generating '4K' Ultra-High-Definition output, but your monitor cannot handle it.
Your monitor might support 1920-by-1080 ?!
Restart your computer, and keep tapping the 'F8' key, until you get a start-up menu.
Choose to start with "low-resolution video", which your monitor can handle.
Then, reset the video to a higher-resolution that your monitor can handle.
Or, connect a 4K-capable TV to the HDMI-output port on your computer.

What does not work?
One suggestion was to connect a 4K-capable TV to the HDMI-output socket on the computer.
Did you try that?
> it's all-in-one pc, message "out of the range.." appears immediately after switch power on.
As soon as you turn it on, press the DELETE key, to enter BIOS SETUP.
Does that message still appear?
If not, exit from BIOS SETUP, and start to repeatedly tap the F8 key, until Windows shows a "repair" menu.
One of the options should be to start with a "low-resolution" setting for your display, e.g., 800-by-600.
Try this, and tell us how far you get, and what you see, and what happens.
