Hello
Nvedia signals cannot be porcessed by Sansui Tv. You have tow options before you to connect your self assembled computer to this tV. The first one is try by reducing the resolution f VGA output. for that, go to Nvidea control [normally will be displayed at the right end of the taskbar] and chage relolution there. By default, the resolution will be 1024/768. Select it to the lowest; 800/600. If the TV display it, just advance it to the next highest; 960/600.
If this does not help you, there is no other way than change the computer's video card to any other, which works on Windows Video Drive. Can be bought from local computer component market, insert it to one amoung the free PCI socket of the computer and do the next proceedings to change over video output from on board video out, and feed this video signal to yur TV. OK.

I would search for a price on ebay. Most suppliers have links to ebay nowadays and let ebay's search engine do the work for you.
Hope this helps.

Go into the menu. Go to CHANNEL and press enter. Go to AUTO CH MEMORY and press enter. Press the right arrow on remote to change the signal type to AIR. Go down to AUTOMATIC SEARCH and press enter. Wait for it to finish on its own. You should have all the analog and digital channels you can get with the antenna setup you have connected to the tv.
