How to connect laptop to HDTV via VGA to Component Video cable?
Using a VGA (Laptop) to component Video (HDTV) cable. When I do make the connection, I receive a garbled picture on the TV. The garble does change as I adjust the resolution via the display settings but still not a viewable image.

Well it depends on the type of component attachment you have there are multiples. Without getting to deep in tech talk if you have component of Red Green Blue which only has 3 connectors VGA does not translate as it sends the horizontal and vertical info down two additional wires. Some Plasma monitors have this hook up some do not. It is generally bnc connections. The sync being off would cause a jumbled signal or no signal at all similar to your description. Possibly there is a better connection on the TV but without specifics of the model that is about as far as I go.
You may have to change a setting in the display to pull in the horizontal and vertical sync (usually listed as "sync on green"). However, more than likely your display is not designed to pull a signal outputted from a computer.
Unfortunately not uncommon ...
Your other solution could be a scan converter. They input computer signals and output video. Can be expensive though - ~$200 or so.
Grandtec makes a converter for it.
