So when i get this mac to sleep and sometime after i try turn it on it gets black screen.

now a days when i turn it off and next day try turn on it start with low resolution it loads with grey apple and then it shows black screen.

and after NVRAM or PRAM or SMC reseting and with 2 or 3 time it only load

my Question is:

If you use you MacBook Pro in clam shell mode, your external monitor will automatically be the primary (and only) display.

See Apple's instructions on clam shell mode for more details.
