Mac Mini Display Issues Dual Monitor

Hi there

I have been having this issue for a while now and cannot find an answer.

Setup -

Mac Mini Late 2014 macOS High Sierra 2 x Acer ED242QR Monitors Connection 2 x Thunderbolt to HDMI


Left monitor image is full screen Right Monitor Image Black Border

Attempts to fix

Changed arrangement - No help Changed to Scaled - No Help in Mirror mode - still black border on RH Monitor Changed cables - No Help Swapped HDMI in back of monitor - black border swaps to other monitor Swapped thunderbolt - black border swaps to other monitor

My Conclusion

No matter what i do when i have two monitors connected, one of the Thunderbolt ports is pushing out an image with a black border regardless of which i make primary (or left) monitor.

Please if anyone has any helpful suggestions i am all ears because i am tearing my hair out with this.
