Exactly... this one simple thing would turn this from a problem to a feature.
Also, at least in my case, it doesn't turn all the lights off when the monitor turns off, but it stops running the service that animates them, so they just freeze wherever they were. If the goal was to use less power, or make everything go dark when the monitor(s) are off, you'd think they'd blank out all the LED's first. IMO it looks really stupid when it's stuck in mid-animation.
Has anyone found a workaround for this other than using a lock screen? I would like the RGB to function as it used to where the monitor status (sleep/awake) doesn't affect the RGB.
