Monitor blanking question

[Martyimac]

Once i upgraded to HS, I have noticed that whenever my 6,1 6 core nMP wakes up, the screen comes on then goes black for a second or two, then comes on and stays on.

I'm not worried about it, just wondering if anybody knows why?

I am still with the 5,1. But I noticed that if I use HiDPI, the monitor may go blank for seconds in some particular situation. I never sleep my machine, so don’t know if that’s the one. But interestingly if I call the “about my Mac”, the screen may go blank for about 2 seconds (not always happen, may be around 30% chance. And only happen after a long time I didn’t launch the About my Mac).
