flickering screen flicker

[Mona98]

Recently it happens that both in game and on the desktop (usually when I have any window open) the image on the screen glitches/flickers for an instant (I can't really describe what happens, but up and down the window seems to break along a column, sometimes showing the contents of the window below or it seems to scan one column of pixels with another), and then everything returns to normal. This happens only on one of the two monitors I have connected, specifically the one set to 165Hz
This is the setup:

• CPU: Ryzen 7 3700X
• RAM: Corsair Vengeance RGB PRO Black DDR4-RAM 3600 MHz 2x 8GB (no XMP)
• MOBO: MSI X570-A PRO AMD
• PSU: Be Quiet! System Power 9 500W ATX Black
• GPU: Gigabyte RTX 3060 EAGLE OC V2 12GB (never tweaked)
• Storage:
  • 1 x SSD 2.5''
  • 1 x HDD 2.5''
  • 2 x HDD 3.5''
  • 1 x NVMe Gen4 M.2 SK hynix Platinum P41 2TB
• MONITORs:
  • PHILIPS Evnia Gaming Monitor 24M1N3200Za/00 (@165Hz w/ DP)
  • TV AKAI 1080P (60Hz w/ HDMI)

This phenomenon occurs both in Windows 10 (clean install, no crack, no tweaking, no dubious tools and not activated) and in EndeavourOS where the phenomenon always occurs on the PHILIPS monitor @165Hz
On Windows I re-performed the clean driver installation with the help of DDU, but nothing changed. Searching the internet I found a file.reg on reddit that was supposed to solve the problem by disabling MPO via windows registry, but nothing. I downloaded benchmarks but they all run great. I responsive without errors on vram with both OCCT and memtest_vulkan. Finally I took a look at the temperatures in the various games and benchmarks, but it's all ok, I then opened the pc, and took a better look at the HW just checking if the various connectors were well plugged in by reattaching the various connections but nothing. As for the monitor settings, I really don't know where to put my hand and whether to put it. Do you recommend anything?
