Dell Precision 7510 HDMI + mini DP ports not working

Hi community

My Dell 7510 both ports are not outputting picture.

I have so far tired connecting 1 one of 2 HDMI monitors to the laptop but non of them get any signals. I connected the cable, the monitor gets detected but the screen is black. This also happens with the second monitor.

Both monitors are working and functioning. Have tested both monitors with RX 580 8GB eGPU connected to the laptop TB3 port and both get detected and have picture on them. without disconnecting the cables, if I plug the HDMI cables to laptop ports, no monitor will show any pictures.

Have tested 2 cables, it's not a cable matter here I'm pretty sure. Both cables are 

working on my 2 monitors,

Also should note that one of my monitors which is a Planar, gets picture when I use a HDMI to DVI convertor but the colors are messed up.
