I have two Dell displays connected to the ASUS GTX 980 Strix graphics card:
- Landscape: Dell UltraSharp U2415
- Portrait: Dell UltraSharp U2312HM
During boot all info is displayed on the portrait display and the image is turned by 90° so it's hard to use.
I’ve tried using different ports of my graphics card and even swapping input cables on my displays but the image is always displayed on the portrait-oriented display. Same on my previous card ASUS GTX 660 Ti.
Any ideas on how to set the U2415 to be the main display?
