Extended output signal samsung neo qled qn90b

[Matija99]

I have Intel arc 770 connected to samsung neo qled qn90b. When I choose extended output signal ON, the screen goes black and it says connect device. It doesn't recognize the device. When I turn it off, it starts to work again. But with extended output signal off I can't use UHD settings. Please help.
