Monitor connected to DP won't work

Ok, so I am getting quite frustrated and mad at manufacturers for using the stupid displayport so much because it appears that it's causing quite a lot of trouble.

 

I upgraded from R9 280x to 5500XT and the GPU has 3xDP and 1xHDMI ports. I have 2 monitors. One is connected using a regular HDMI port and it works. The other one is connected using DisplayPort ->DVI cable because the monitor is old.

 

The monitor on HDMI only works in windows when the drivers are installed.

 

The monitor on DisplayPort works in BIOS, windows boot screen and when the GPU drivers are NOT installed. They never work together. When the drivers are installed, windows only detects one monitor. I have been trying countless solutions found on google but none of them work. The only thing I quite have not tried is to reinstall windows in UEFI mode because for some reason the bios was defaulted to CSM and I installed windows that way. Uninstalled old drivers using DDU in safe mode and installed newest drivers found on AMD website...

 

Anyone got any other solutions?

Searching on google it appears that Nvidia has had similiar problems 😄

 

uhh, I don't have 2 DP cables, only one. However, none of the monitors work in windows on DP with the drivers installed.

Update: Switched to GTX 660 for testing and both monitors work. One is still on DP->DVI cable and the other one is on HDMI. Just wtf is going on...

Well, turns out you were right, bought a 15e cable instead of the 6e one and it finally works. This is retarded
