Dual Monitor Resolution Issue

Hi all, I know that there’s various ways of running FSX over 2 monitors. I have a MSI Radeon RX 5600 GPU which allows me to use AMD Eyefinity and span across the 2 displays as if it was one (3840x1080) but I don’t like the fact that the centre of the screen is now on the screen bezel and cant find away of moving the centre to the left so the centre of the left monitor is looking forward and then the right screen is spanning to the right providing peripheral view to the right. Either way I gave up with that thought so was just trying to add an additional view on to my right hand monitor and the resolution of the extra view window is magnified as if it won’t provide a 1920x1080 resolution and as such everything in that window is blurry. Any thoughts please ?
