View Full Version : VGA to RCA and no TV-Out

06-08-2010, 05:41 AM

My laptop has a VGA port on the back. My TV is an old CRT box, and has only svideo and rca inputs. I purchased a VGA to RCA (+svideo) cable but it turns out my laptop doesn't support TV out. The video is black and white, uncentered, and blinks a ton.

The laptop has a Radeon 3100, with newest drivers from Toshiba (because ATI drivers don't want to install and tell me to go to manufacturer's page).

Is there anything I can do, or do I have to get some kind of signal converter?

Thanks. :)

Check that your output settings are the same resolution/refresh rate of your television.

if it is a CRT TV then the MAX resolution you can have without tinkering should be 800x600 but NOT over composite RCA. if i recall that is only 640x480
S-Video is the only one that can support 800x600 i THINK.
if the picture is black and white then the adapter you have is faulty, and honestly, i do not think i have ever seen a VGA to composite, because the video signal from VGA is not a singal stream, it is actually red/blue/green and also has green sync, v-sync, h-sync, etc.

VGA to S-Video is possible and better

here is a VGA to composite & s-video. - http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10401&cs_id=1040113&p_id=2509&seq=1&format=2

but usually the black and white picture would denote the adapter is bad or the RCA plug is bad or even maybe the composite video on the TV is bad.
