Second HDMI-port on my GPU doesn't work after reinstalling win10 (I guess)

So I reinstalled Windows 10 a while ago because there were some system errors etc.

Until then i used my main screen (HDMI-port 1) together with my TV (HDMI-port 2) together and it worked perfectly.

But now the second port won't work for either and the first works for both. My TV recognizes the cable but my PC doesn't regcognize the second screen.

(I am not 100% sure it's because of the update though)

I already reinstalled all Drivers but Nothing.


My PC runs a Radeon RX 580 4096 MB

Radeon Software version 18.7.1

Windows 10 Home 64 bit


Thanks for helping, Adrian
