Hi there,


First of all, excuse me if my english is not all that great. I am from the Netherlands so it is not my main language.


I have a problem with my MSI RX 480 Gaming X 8 GB and i can't seem to find it after searching and testing for almost 3 weeks now. I hope you guys can help me.


Before i used 2 screens and this worked out fine:


- BenQ XL2420t 144hz (displayport)

- Medion 1920 x 1080 60hz (HDMI)


Since 3 weeks i have bought a new main screen, Iiyama GB2783QSU, 70hz AMD freesync, 2560 x 1440 (via displayport), my second screen (benq) does only work via hdmi and is not working with displayport.


I think the problem is the outmost displayport connector because no matter which monitor or cable i use, the displayport most to the right is not working.


I tried the following:

- uninstalling drivers with ddu and reinstalling them from AMD

- switching cables (even bought a new one)

- starting up with one screen on the displayport most to the right

- power cycling and resetting all screen related settings in both monitors and PC

- installed latest windows updates and directX settings

- installed previous version of drivers

- installed MSI game center, control center

- tried it with and without radeon software


So i don't know what to try more and i hope someone can help me or maybe tell me how i can determine if the port is maybe broken because it still has warranty.


Thank you in advance!
