Displayport does not work. I assume it is a “heads” problem or I damaged the hardware while assembling: it worked before flashing heads. I hope this helps somebody. Otherwise everything is fine!

I think it’s a monitor problem, because i use a x230 and a t440p with the same heads version and some monitors work some don’t. How does it look like for you? Just a black screen as if it has no signal or is it trying to connect endlessly without results?

The monitor just does not find it. Looks like no cable connection et all. I contacted nice people from heads. Indeed, my model comes with dGPU. So, the displayport must be connected to the nvidea nvs 4200 chip. So, I will try a doc station as a simple solution…thank you for the reply!
