I connect it to my screen and pc and it keep saying no signal (it even dont recognize it)

tried with another PD and nothing aswell

what should I do?

both lead bought at same shop, maybe the problem becomes from pinnes of the leads?

I assume you are talking about the display port cable?
Do you have a secondary monotor you can try it on.

nope, just this one, the other monotor just have HDMI nothing more :/

You can try to

1. Make sure display port is inserted to GPU not MOBO. (Some people make this mistake)

2. Update GPU driver.

If the above two doesn't work, you'll have to get a secondary pc or monitor to troubleshoot it :/

sure thing, thanks you, maybe is my actual pc trouble tbh.

friday i get my new one and will try it out.

thanks mate for real
