I just bought a Dell Optiplex 7000 which has UHD770. It also has the latest deiver (188.8.131.5279).
It has 12th Gen i7-12700T and 32GB of memory and using Win11.
I'm using 2 x DELL U2515H monitors.
I cannot get both monitors to display 2560x1440. On one of them, the highest recommended resolution is 2048x1152 and much I have tried, I cannot change it.
I may be being extremely dumb. Help anyone?
