hi guys, everything has been fine with my eyefinity setup for an absolute age, until yesterday when i would go from my 3 27" monitor setup eg use them as 3 separate screens, i would then just go and setup my eyefinity and i would get eyefinity but the left screen would have a 2 1/2" big black bar at the top of the screen the middle screen would have a 2" black bar at the top of the screen and the right monitor would have a 3 1/2" black bar at the bottom of the screen. this only started yesterday i rolled back my pc and after some fiddling got everything back to normal. i got on my pc today to do some sim racing so i tried to setup my eyefinity again and the exact same problem. i checked my windows screen resolution and it shows that it will not let the eyefinity go above 5760x876, not the 5760x1080. i have made sure that i have windows set to not download and install their downgraded drivers. i have deleted my amd drivers and reinstalled them but still the same, any help would be really appreciated thankyou.

as i have said this issue never started until yesterday
