I have a problem with my new Acer BE270U display. It has an extreme lag at resolution change and UAC prompt. It takes more than 3 s to this monitor to adapt to the new screen settings (screen is off) which I consider very terrible. This is my first Acer monitor so I don't know if somewhere is a bug or it's a feature of this brand? I have experience with Dell, HP and LG monitors, even very old, that adapt immediately. In the video there is my dual monitor setup with BE270U (@ DP 75Hz, but 60 Hz with no difference) and 11 years old HP LP2065 (@ DVI 60 Hz) showing opening and closing the UAC prompt. Running on newest AMD Adrenalin 2019 graphics driver.
