I have the Power profile set so that the NUC never goes to sleep, and the monitor turns off after 15 minutes of inactivity. Occasionally, but not always (which of course makes things more difficult), when I try to wake up the monitor by moving the mouse or tapping the space bar on the keyboard nothing happens. When I turn the monitor off and then back on, I will sometimes get a "No HDMI signal received". Sometimes I have to power off the NUC to get a signal, which is not good.
The monitor is a generic Asus product, and I'm connected via a HDMI to DisplayPort cable, and I'm operating with W7, 64-bit Home Premium.
I'd appreciate anyone's thoughts on this.
