Tip & How-To about Televison & Video
If you are trying to connect computer to LCD TV and get no signal, as a first thing do the following:
Double check cable and connection. If possible test different connections. Try using VGA, DVI or AV, depending on availability on computer and TV.
Ensure that Video drivers on computer are properly installed, and that the video adapter is working properly.
If you are using a laptop, ensure that you do not need to use a function button to enable the external display, this is pretty common on laptops.
If you are using a desktop, go to display properties, find the windows where you get the picture of two monitors, and ensure that both monitors are enabled.
On Vista try also using the 'Identify Monitor' button on Top. It is located on same properties panel as the two monitor, the main Display Property windows. From the same window you can also modify display resolution, as explained later.
If still no luck, then it may be a problem of synchronization between TV and computer, in that case try the following.
....If that does not work.
On computer, go to display properties.
First try changing computer resolution. The TV max resolution may not be available on computer. In that case try lowering down to the smallest 16:9 resolution available on computer graphic settings (usually LCD TVs are 16:9), and if that does not work, set resolution to 800x600, just to test (picture proportion will be distorted, or you get squared box on a 16:9 TV).
If that does not work, open Display Properties. In Display Properties access Advanced, and then Monitor settings (XP). On Vista choose Personalize in control panel, then Display Settings, and go straight to Monitor Settings, in there again go to Advanced.
Under the advanced monitor settings you will find a tab called monitor, in there you find the monitor frequency. Try setting this to 50Hz, if that does not work try 100 HZ, that is the output frequency of your TV. If you get unsupported frequency, revert value to normal.
