Question Trying to dual monitor on PC without success... Help needed!

[0001punk]

Greetings all.
For the life of me, I can't figure out why I can't use 2 monitors simultaneously. Please help me so I could work on 1 monitor while the other plays videos of cats

Specs:
- 2x 8GB RAM
- Nvidia Geforce GTX 1050 TI ( Ports: 1 HDMI, 1 DVI, 1 DisplayPort )

• MSI MAG Z390 TOMAHAWK (MS-7B18) ( Ports: 1 HDMI, 1 DisplayPort )
• Nvidia GeForce Experience + Nvidia Control Panel with latest drivers updated
• Monitor A: SAMSUNG S24C350BL ( Ports: 1 HDMI, 1 VGA )
• Monitor B: SAMSUNG S24F350FHM ( Ports: 1 DVI, 1 VGA )
• Cables: HDMI-HDMI ; HDMI-DVI ; HDMI-VGA ; VGA-DVI ; DVI-DVI

Both monitors work alone, in all the ports with all the cables, so there is no port/cable/monitor hardware issue as far as I can see.
When both are connected to the GPU ( 1 HDMI-HDMI, 1 DVI-DVI ) nothing seem to work. Tried all possible combinations, including connecting one to GPU and one to the Motherboard.

Please help.
Thanks.

When both connected, it seems the HDMI port of the GPU has priority over any other port.
While Monitor B is connected to it, monitor A is black screen no matter what other port I use
While Monitor A is connected to it, none of them work, both show black screen and the LED light is flashing, meaning it's connected but "PC is not ON""
