In the past week my monitors have been shutting down and losing signal while playing games. It occurs frequently and they don’t turn back on, even when unplugged. I leave one on and the other off, and vice versa, but nothing restores the display. After restarting my PC, it still boots without a screen. A few restarts have resolved the issue, or I’ve just given up for the evening and tried again tomorrow. The Event Viewer shows LiveKernelEvent errors (117, 141, 1a8, 1b8).

I asked someone who might know better, and after a couple of days they informed me it was one of my monitors. They said it kept flickering and cutting off even when idle or during long sessions, whether I watched for 30 minutes to 2 hours. If it were just one monitor, it’s strange that the other one would also flicker, though that could easily be possible.

I feel uneasy about it being a simple faulty monitor, yet they suggested buying alternatives. Since then I’ve brought my PC back home with the monitors and haven’t experienced any problems. Also, he didn’t specify which monitor was faulty, and I have two identical units, so I tested each separately on another PC—both worked without issues.

How do these connections work? Should I suspect a problem with my own monitor or investigate further?

Welcome to the forums, newcomer!
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
"Despite testing it with another computer, utilising multiple different connectors and cables, the monitor would repeatedly flicker and cut in and out."
So the person you took it to hooked the monitor up to different display outputs to rule out the driver and/or OS weren't to blame. How old are the displays you speak of? Depending on your monitor, there might be a firmware update that you display might be pending...? If not, then the display might've conked out due to wear and tear or age.
I tried each of them individually and with another PC and they were fine - no flickering.
The only thing that's changed since you shipped it out and then brought them back in was the power source, are you sure your wall outlet doesn't have a grounding issue?

Sorry! Please find below the details you requested.
CPU: i7-9700K
CPU cooler: Unknown exact model, appears to be the Be Quiet! BK030 Pure Rock Slim 2 Air CPU Cooler, 9.2cm PWM Fan, 130W TDP, CPU Cooler
Motherboard: MPG Z390 GAMING PRO CARBON (MS-7B17)
BIOS Version/Date: American Megatrends Inc. 1.B0, 12/10/2020
Ram: 64gb (4x16) CORSAIR Vengeance LPX RGB 32 3600 MHz DDR4 Memory Kit - 2 x 16 GB
SSD/HDD: Samsung SSD 980 1TB, Seagate Barracuda ST3000DM007 5400 3TB HDD, ADATA Ultimate SU630 240GB
GPU: NVIDIA GeForce RTX 4060 Ti
PSU: AORUS P750W 80+ GOLD Modular
Chassis: Unknown
OS: Microsoft Windows 11 Pro
Monitor: LG 24GL600F 24” 1080p 144hz
This PC was assembled previously and purchased in 2020, together with the monitors at that time.
My worries about the monitors were whether they had been tested and if one of them would flicker in and out. However, I have them back in my home setup, and none of this occurred. I didn’t observe any issues even under higher loads, except for complete shutdowns rather than flickering. I restored both monitors to their original positions before installation, as I personally tested them independently and did not notice any problems.
I hope this clarifies things and thank you for your response.
