Laptop to TV –> some signal but useless

by namasamaran . Updated 15 years, 8 months ago

My Video Card is listed as: ATI Mobility Radeon HD 4670

My laptop is Dell XPS Studio 16 with Windows 7

My TV is RCA, 9 yr old, CRT, the only connection is AVI in and antenna

My DVD is Samsung (also DVD recorder) with all sort of connections in the back

First schema:

* The first cable is from Cables Unlimited * VGA to TV-out S-Video Adapter * with the blue VGA connector attached to the laptop and at the other end has 2 cables: S-Video out and yellow video out.

* Connected the yellow video out to the video-in connector in the back of the TV.

* Change the monitor display to ‘duplicate’ (the menu says: Control Panel – Appearance and Personalization – Display – Connect to a projector)

* Change TV channel to Video (channel 00)

Result: get some sort of signal, but absolutely no use as you can not see anything on the TV screen but a barely visible severely distorted image of the desktop.

Second schema:

* Using the first cable mentioned above

* Connected the S-video out to the Samsung DVR using S-video cable from Belkin

* Change the monitor display to ‘duplicate’

* Change TV channel to Video (channel 00)

Result: worse than the first schema, as nothing displayed on the TV screen, just black static screen

Is there any configuration I’m missing here? How about the laptop monitor resolution? I changed it to 800×600 the using the yellow video out (first schema), but the TV showed rainy violent horizontal lines. The same result occured when I changed the rate from 60MHz to any other numbers.

Please help. Thank you

Also bought Y-audio cable from Belkin for the audio:
