I have a couple of Dell monitors (different models) with DP ports in a multi-monitor setup (5 monitors). To prevent the wake-from-sleep issue (where Windows doesn't see DP monitors right away and thus rearranges windows to fit the monitors on HDMI and DVI), I have changed the input source on those monitors from Auto Select to DisplayPort.

But after a sleep-wake cycle, the monitors have reverted to Auto Select.

How can I get these monitors to keep input setting at DisplayPort?
