Question Monitor to laptop, screen goes black to normal repeatedly.

I am connecting a monitor via HDMI to a laptop.

Here is the laptop Amazon link;

Here is the Monitor Amazon link:
https://www.amazon.com/GFV22CB-Ultra-Compact-G-Sync-Compatible-FreeSync-Zero-Tolerance/dp/B082DNTXJ6?ref_=ast_sto_dp

I am using a 4ft HDMI cable:
AWM E230809 20276 80°C 30V High Speed HDMI Cable with Ethernet.

The laptop's GPU is Nvidia GTX 1650 Mobile. HDMI port is 2.0.
The monitor's HDMI port is 1.4.
Display Port cannot be tested, because no DP port on the laptop.

While the monitor is connected to the laptop, if the refresh rate of the monitor is set higher than 60hz, at certain times, the screen of the monitor would go black for several seconds, then to normal, repeatedly. During this, the screen is operational, mouse can be moved, words can be typed, just can't see it. At first, it was doing this all the time when the monitor was used past the desktop screen idle state (opening tabs on browser, playing video or a game). At that point, I used DDU to uninstall the Nvidia Graphics driver and reinstalled it fresh from the official driver site.
This sort of fixed the issue, but it still persists. Now it would randomly black out once while idle or while doing anything. Also, I believe that dark screen scenarios may cause this. If I go to the reddit website, in dark mode, it would repeatedly start going black to normal, until I go to the other tab or close the tab.
I have ruled out the HDMI cable, as it is brand new and I tested with a different one, which does the same.

So far I have:

Used DDU and reinstalled Nvidia Drivers
Messed around Monitor settings
Messed around in Nvidia Control Panel settings
Tested a different HDMI cable

On additional note, I've tried to test the colors of the monitor, and went to a website that would let me set the entire screen Red/Green/Blue color. Whenever I choose the Red or Green colors, I would have horizontal lines appear flickering on the screen. The next day, I tested that again and no horizontal lines were appearing. Is this because the Monitor can be heating up?

Any help would be appreciated.

Welcome to the forums, newcomer!

What BIOS version are you currently on? You can use CPU-Z to tell you that info if you're unable to jump into BIOS(after Asus splash screen). What OS are you working with? If you're on Windows 10, what version(not edition) of the OS are you on? As for your cable, try and source a cable from a friend or neighbor and see if the issue persists. As for your panel, perhaps try and see if another donor system exhibits the same issue.

Bios version 316
Windows is Windows 10 21H1 Build 19043.1526

I have tried using a different HDMI cable, and it does the same.
I am not able to test this monitor on a similar device to this one. It works fine on older computers and consoles, which do not require refresh rates above 60hz.

Attempted further testing.

I was able to raise the refresh rate of the monitor step by step up to 95hz. Any further than that, it starts to break.
