I have an M900 Tiny that has a intermittent problem with dropping brightness on the displayport out. I'm not setting it anywhere. Sometimes when coming out of sleep (windows 7 x64 Pro) it just won't send video. I can swap the DP cable to another monitor and the problem is the same. A hard reboot solves it, leading me to think it's definitely something WRT the sleep/video configuration. I've had it running in Maximum Performance power mode with no OS sleep settings, just 'turn off the monitor after 6 minutes'. The video driver version is: 18.104.22.16874 This is a somewhat recent problem, as it hasn't always done this. Anyone run into a similar situation? And found an actual fix/solution? Not just guesses, please.
