Question Monitor randomly disconnecting and reconnecting

My monitor (ACER KG271U X) is randomly disconnecting and reconnecting. Been happening for about a week. I switched the display port and power cable and it was still happening. I’ve got a dual monitor setup and I found a “fix” where I switched off of 240 htz and made it 144htz and it hasn’t been disconnecting, does anyone know why or a fix to this?

GPU : Nvidia 3070 Founders Edition
CPU : Ryzen 7 5800x
Motherboard : B450 Aorus M
Ram : 16 GBs
PSU : Seasonic S12lll 650W
Storage : ADATA SU760 512GB (SSD),
Seagate Barracuda 2TB (Hard Drive),
Samsung 970 EVO Plus (M.2 SSD)

OS Information : Windows 10​

Update your post to include full system hardware specs and OS information.

PSU?

Disk drive(s)?

What is the other monitor and how are the monitors connected to the host computer?
My PSU is Seagate Barracuda 2TB (Hard Drive) and i have
ADATA SU760 512GB (SSD), Seagate Barracuda 2TB (Hard Drive), Samsung 970 EVO Plus (M.2 SSD) as my disc drives. My other monitor is also a "BenQ GL2460".

Seasonic PSU (versus Seagate?) Wattage, age, condition?

Clarify:

Main monitor ==== Display port ====> GPU or iGPU?

Second monitor ==== HDMI ====> GPU or iGPU?

Check both the supported monitor configurations and the monitor drivers:

Seasonic S12lll and it has 650 watts.

Age : About a year and a half

Condition : Good, although it has a decent amount of dust in it

Both monitors is connected into a GPU

I've downloaded the newest monitor drivers. I've had the monitor for a couple months and all of a sudden it's disconnecting and reconnecting, but like i said it hasn't been doing it on 144htz. I still have the warranty on it, just wondering if it's the monitor messing up or if it's something else.
 
If possible try the monitor on another known working host computer.

Or try another known working monitor on the current host.

And any other monitor/computer/GPU connections that are viable.

May take a bit of time and effort to swap things around to determine what works and what does not work.

Just be methodical and keep notes.

Objective being to determine if the problem(s) follow the monitor or stay with the computer.

And do remember to use Nvidia's control panel to check the configurations.

Should be accessable by right-clicking an empty spot on the desktop and clicking "Show more options" > Nvidia Control Panel.
 
Unfortunately cannot try it on a different computer. My other monitor doesn't have 240htz, so there's no way of me telling if it's cause of that. I've tried a different display port on my GPU and it still occurred. I think i messed around with the Nvidia control panel to confirm that it's not the reason my problem is happening. I think i'm just going to use the warranty, and get the same monitor and if it still happens, i think the only logical reason would be the PSU, unless there's a setting on window i might of changed that triggered this.
