[SOLVED] Second monitor recognised but shows black screen

[SneakyGuy]

I seem to have a very weird problem. I have a dual monitor setup that was working fine for the past year. I had to move so I packed my setup to move it. Of course I removed the GPU so it doesn't fall off. When I setup my PC again my second monitor doesn't seem to wanna work. My first monitor is working fine. The second one works with DP but not with HDMI... It has 2 hdmi ports and they both dont work... The monitor is recognised inside windows but its just a black screen... I also tested the hdmi cable and it works fine on the other monitor.. i have no idea whats causing the problem.. everything worked fine literally one day ago...

Also I pulled out both ram and gpu and placed them back in to test if its gonna work but no luck..

Specs:
Ryzen 1600
Gigabyte AB350 Gaming 3 rev 1.0
2x8GB 2933MHz
Gigabyte GTX1060 3GB OC
Corsair VS550
First monitor: Dell Alenware AW2521HFL
Second Monitor: AOC C24G1 Curved

Update: the monitors seem to work together if i switch the cables... i dont understand why though...

I found the solution... I didn't remember that you had to choose the port on monitor settings... i just chose hdmi and it worked...
