So i Build a PC with a AMD Ryzen 9 7900X, AMD Radeon RX 7900XT, GIGABYTE X670 GAMING X AX, be quiet! Pure Power 11 FM 1000W, be quiet! Silent Loop 2, 32GB (2x 16GB) Corsair Vengeance RGB grau DDR5-6000 DIMM CL30-36-36-76 Dual Kit.
The PC has the Problem, that one of my Monitors does not receive a signal from the GPU wenn all Monitors are connected(USB-C to DP).
The other two Monitors are connected over DP and they work perfectly fine.
If i deconnect one of the DP to DP Monitors the USB-C to DP can turn on with start.
