I have a Sony Vaio VGN-NS25G which has VGA output and I've had some good times connecting it to my flatmate's Samsung LCD TV which has VGA input and putting the sound through the earphone jack.
However, I found a deal I couldn't resist for a 5 year old LCD Panasonic Viera. This old girl only has S-video and composite in so I'm a bit stuck with connecting my Vaio to the TV.
I found a cable thing which I thought might work: http://www.i-laikee.com/images/dix_vga0001.jpg
But I gave it a go, made sure I had turned on duplicate monitor display, but just got a blue screen on the TV.
There was some hint that maybe I needed to reduce the screen resolution from another site - could that help?
My flatmate also suggested that my video card needs to have TV out in order for the cable to work. Isn't that implied by the existence of a vga port?
