When I turn on my laptop, I am guessing it works but monitor doesn't. Monitor goes blank/pink screen; Nothing shows at all. So, I thought lets try with external monitor. External LCD monitor shows "Input not supported"

Any help will be appreciated.

Sounds a lot like a graphics card issue. Does it display anything during boot-up? –  Darth Android Dec 7 '12 at 16:43
Is the screen blank or pink? What OS are you using? What hardware? Is the external monitor VGA, HDMI, DVI or what? Can you hear the laptop's fans or HDD working? –  terdon Dec 7 '12 at 16:44
I can hear the fan and HDD working. Trying with VGA to external monitor. Doesn't display anything during boot up and even after. I would say blank rather pink. Windows XP.Thanks.. –  Hoping Dec 7 '12 at 16:48
does your laptop have a function button to enable the external monitor? usually its Funct + F8, but look for the function key with a rectangle that looks vaguely like a monitor. if you hit it, does your problem go away? –  Frank Thomas Dec 7 '12 at 16:52
Boot into safe mode, this should force the output to display in a low resolution supported by any monitor. If you still don't get a display on an external monitor then your graphics chip is likely to be duff –  Tog Dec 7 '12 at 16:52
