I'm using a DB15 (VGA) cable to connect my laptop to my Videocon TV. I am unable to see any display. On Googling, I found a post on configuring xorg.conf to send output to TV using SVIDEO, but the same does not work for me. I did the modification mentioned and restarted my X-server, but saw a "Invalid mode" message on the TV instead of the "No signal" message. I did change my TV to VGA mode.
The refresh rate shown at the back of the TV is 50-60Hertz. I also tried adding modeline entries in my xorg.conf. I even restarted my laptop hoping the display would get configured, but to no avail. How do I get this working?
