I upgraded from the RX 460 to the powercolor RX 7600 hellhound and the displayport is not working, when I turn on the computer the monitor that is connected to the displayport works until it enters the windows part then it stops giving a signal and the hdmi monitor turns on , the monitor appears in the Windows settings, you can change the resolution but no image appears.
I use a displayport to vga adapter but the problem is not that because it works perfectly on the rx 460
my setup:
GigaByte H61M-S1
GPU: Powercolor RX 7600 Hellhound
CPU: Intel core I7 3770
Memory: 2x 8GB kingstom DDR3 1600Mhz
