Yesterday i upgraded my system from an old Intel cpu (8years old) to a new r7 7800x3D with a B650M . Until i unpluged everything both monitors were working perfectly . After the new instalments i can only detect and work on my main screen with the second screen not been detected at all . I tried it with and without the GPU in the system . I tried reinstalling drivers and rolling to an older version Connection is fine (checked on both DP sockets) Second monitor works outside of this new system Since graphic card is the same i can only imagine a software issue either by Adrenalin now detecting 2 GPU or by the new CPU .
Edit , tried an other monitor also with and without the GPU and also tried my main screen on the DP instead of the HDMI (all 3 DPs ) can't read it still . Also tried disabling iGPU of the 7800x3D and working only the GPU , problem still there .
