Incorrect DisplayPort version Arc A380 in Windows 11

[Owleye]

Two displays:

My desktop PC boots up with the board manufacture's logo on main monitor, I can use the EAUFI settings menu on that monitor just fine.

Once windows boots the monitor goes blank and displays a "Incorrect DisplayPort Version". 

I have tried:

Setting the monitor to 1.2, it just states No Signal Present.  So back to 1.4

uninstalling and reinstalling the display on Device manager.  No effect.

The DM says Arc.

Swapping cables has no effect, using different ports on card no effect.

The ARC version is 31.0.101.5186

Monitors:  32BL75U -WA.AUBQNPN

Monitors work fine with a Dell laptop, and Windows Surface.

Did your system use to work before with your 2 monitors when using Arc A380? Or is this an out-of-box issue?

Any recent changes (hardware/software) made on the system?
