Display port not working

[toastdude123]

I have posted something like this 3 weeks ago and still no luck, I hope I can get some new eyes on this topic.....

 

When I start my desktop my display boots up and then  "No Signal" appears, so then I switched my gpu and it did the same thing again. Every port works but the display port.

 

I don't know how to see if its a cable problem, monitor problem, or a driver problem. I only have one DP cable.

Well first off it would help if you had another displayport cable. if you can pick up a second one even if it's just a cheap one you can at least rule out the cable as the problem. if you can try checking the connector on your GPU and monitor and check to see that none of the contacts are broken.

I'm having the same issue except that I don't have a DP cable and the other ports, DVI and HDMI both don't work on both onboard graphics and my Radeon HD 7750.

Ok, I will buy a new cable on amazon tonight and I will contact you via this post when I get the new cable and test it out
