Toshiba satellite P775 black screen windows 8

Hi, I just replaced a cracked screen on my laptop with a new one 17.3" which should work with my laptop. When I start the machine it's show bios picture, and then start to load windows 8! When the windows screen is ready to show home screen the screen go black! I've tried to boot on a windows 8 cd to refresh the machine I see it complete 100% but when it's loading into windows black screen again!? Shouldn't windows know the new screen by default? Will a recovery do anything with this problem???

Pls need an answer.
Ty in advance
