alienware m17x r4 laptop display problem


I bought my Alienware M17x R4 laptop few weeks ago and I`ve problem with the display. The display not smooth, I see many pixels especially on blue and green background and around the alien head. Sometime complete horizontal lines shows. I refreshed Nvidia driver (gtx 780m), but I can`t HD4600 driver, the installed has been failed. I run boot system detect, it doesn`t shows problem, but the display still same. I can`t try with external monitor or tv, so I don`t know that is display or hardware problem.

Anyone can help me?
