My old monitor, the PG279Q, had an option to disable this terrible setting. Now on the XG279Q without the option to turn it off, getting into the BIOS is nigh impossible and also every time I bootup and turn my monitor off/on, Windows thinks I have no monitor connected and it messes up multimonitor setups.
Please, update the firmware for these monitors so that we can disable these awful settings. They're ruining an otherwise decent display.
