Intel Arc A770 dual monitor issues

[CS5624]

Hello there,

I recently purchased a brand new Intel Arc A770 16GB Limited Edition Graphics Card.

Considering that i do PC builds around, for my family, my wife and my friends, i consider myself well aknowledged about this things.

I started notisic my right monitor would randomly go black, loss of both visual and sound, to then come back.

Tried:

Reinstalling windows, nothing.

DDU drivers, nothing.

Resetting BIOS settings, nothing.

Changing DP cables, nothing.

Changing GPU (with the old one i had), works!

So.. what's the issue here?

Why does my monitors would randomly go black?

When opening a game i usually plug out the dp cable and then reconnect in and the monitor comes back, which doesn't make much sense to me.

Considering that i have 2 4k monitors with DP 1.4 interface, should i plug in DP cables 1.4?

Actually having DP cables 2.1.

I also right now tried putting in HDMI cable, but now the HDMI cable works, and the DP monitor doesn't work, but before connecting HDMI one it was working.

What the frick is wrong with ARC? I'm losing my mind.
