    Afternoon Guys, first time poster after a bit of help. Hope this is in the right section.

    Basically i'm trying to get my laptop to display on my LCD TV through the VGA port. The laptop recognizes that their is a second monitor there, however when I click 'duplicate display' etc the TV still shows 'no signal'. I've tried a mates laptop on the same TV using the same cable and it works fine, so I know its my laptop thats the problem.

    My graphics card is a ATI Radeon HD 4330. I've played with some of the settings in Display > Screen resolution and the ATI catalyst control centre, but to no avail. Like I say both confirm that are a monitor is there and they appear to show it is working properly. It is identified in control panel as a 'generic non-pnp monitor', and I can tweak the screen resolution etc, however the TV just continues to show no input detected.

    Any help you can give me is much appreciated, if you need any more info let me know.

    Do you have the latest drivers from AMD?

    @ jaybridden

    Have you tried connecting the laptop via the VGA port/cable to a [regular] PC monitor (rather than the LCD TV)? If so, do you still get the 'no signal' message? If so, maybe your VGA port on the laptop is damaged/faulty(?)

    the TV may not be supporting a resolution your laptop is using... I've seen it before
    you should try putting your laptop to external only display mode... no laptop display... if that works, then that's what the problem is
