Good morning EveryOne,
i'm using kde neon on Desktop system with Amd ryzen 7 7700 without dedicated graphic card, 2 monitors, with 32gbRam and 1Tb nvme.
For two times i got black screen on all monitor, the system continue to work but the monitor remains black, i'm obblied to reset my pc.
Why i'v this problem? Where is the cause?
thanks guys

Anyone help me? pleaseee :/

It can be bad monitor cable, too long, or not suitable for your monitor resolution (hires, or hdr needs more bandwidth).
Worst case - your Graphic card is dying.

Could be graphic driver problem as well.
You can try desktop with wayland and with x11. See if you get the same problem.
Second, try another live distribution. If Problem persist, then is probably HW problem.

The CPU (and insided Gpu) are new. I've buyed it's ten days ago.
I can proced for steps, the connector monitor it's:
1 display port included in the box of the monitor (MSI)
1 hdmi for a small monitor hp
Now i've disconnected hdmi monitor
i will update you about this

As i can try wayland with x11?

Thanks
