Problem when I plugged in HP monitor model x2301 to my Acer Nitro 5 AN515-52

I've searching how to solves this problem anywhere. Nothing works so far now. Here's my scenario, I'm connecting my acer nitro 5 to HP monitor and It's works for a few seconds or minutes, then the monitor turned black likes it's in sleep mode. If I'm using Extend as my Project setting, the laptop screen works but monitor don't. When I turn off the monitor or plugged out the HDMI cable and plugged in everything once again then it's work for few seconds but it's turn black once again. So if I wanna use it, then I need to repeatedly do the same thing until the monitor won't turn into black anymore, this so annoying. Is this the driver problems? or laptop problems itself? I already used another monitor which is Acer Nitro Monitor, it's not helpful at all. I already install both monitors' driver into my laptop and using 2.0 HDMI and even 1.4 HDMI, just facing the same thing.

Congratulations. Thanks for report. It's also possible that the AC adapter is not properly grounded or isolated from the AC mains.

If monitor turns back on when you press FN+F5, then you're timer is set turn off monitor every few seconds.

But if want to turn off this thing, how can it set the monitor ? Is there any settings inside the laptop or I have to find the setting through the monitors' setting itself? 
Btw, since I write this looking for help. Idk why my monitor (secondary monitor) just be nice to me. There's no more turn off and on after few seconds. Hmm there's something make me curious😕

Search 'power plan' in Windows start menu. Click 'edit power plan' near top of start menu. Please show screenshot of power plan.

Does the Acer monitor behave exactly like the HP monitor?

yes, any monitor will be the same thing. But here I found something. Since I'm too curious about this problems. I tried to measure the input current to my laptop, but I don't have any measurement device. So I try to plug in any speaker to check if any leakage current or anything. Since I've  learned some basic electronic from school, the speaker made some weird "brrr" sounds when I plugged it in which telling me there's must be grounding or electrical problem. So I'm suspecting current leakage due to grounding problem or probably comes from malfunction USB part (I used all the USB ports on this laptop, lol) I tried to wiggle some USB port and the speaker stop "brrr"ing. Then I try to restart the laptop once again and VOILA!! no more problems. It just like gone, GONE. So I recognize one of USB port kinda rusty. This might be the main problem leading me into this.
