Samsung monitor of desktop computer is not able to display and show Not optimal mode error Recommended Mode 1440x900 60 hz while I connect it to cpu but it works when i check it from my laptop (extended window). So my question is How to solve this problem. I had gone to certain website in search of the solution (like here)but couldn't succeed in solving it. I expect solution from experience user. It work when I open in safe mode and When I reduce the resolution and restart window in normal mode I again loop in above error.

Configuration:- Operating System :- Window 8 x86 bits

Your question is very unclear as written. I assume when you say CPU you mean a desktop computer. Is the issue that laptop display the correct resolution and your desktop won't? –  Brad Patton Apr 25 '13 at 15:21

@BradPatton I had updated my question... –  nKandel Apr 25 '13 at 15:41
    
Both the laptop and the desktop are running Windows 8? If the desktop is not displaying the optimum resolution, then what resolution is it displaying? –  dtmland Apr 25 '13 at 15:44
    
Thank you. So what resolution is the monitor at when you receive the error message? Or is the screen just black? (60 Hz is not a resolution, it refers to the refresh rate) –  dtmland Apr 25 '13 at 16:32
    
@dtmland When I reduce the resolution and restart, error message animated in black screen. –  nKandel Apr 25 '13 at 16:53

Though this may not be good solution but If I Were you, I would tried to re-install the operating system. (Which may adjust the environment for screen resolution and refresh rate during installation)
