No signal from your device

I have a problem with connecting my laptop to my external monitor. I connect it with HDMI and I had no problem until last night I unplugged it and when in the morning plugged it back it does not show anything. the monitor says “no signal from your device”.
I connect the monitor to another laptop with the same cable and it works. and the HDMI port on my laptop doesn’t seem to be damaged.
could someone please help?
