VGA -> Composite convertor

[Light Console]

Pah! just fixed the USB's, had to un-install infrared modem for an old Nokia 'phone, then they worked. So have ditched all and gone for a USB TV tuner box. Thanks for posts, and to Lightguy, great idea, which hadn't crossed my mind (which is not a long journey ;) ). However, as it will be used in Menorca, Spain next year, I was unsure if they had Digital, and if they did, would it work the same?!?

hi,

I use a videonics MX1 vision mixer, but when I use it with a laptop the screen is very flickery and weird..  I'm using the S-video output from the laptop.. any ideas why this might be?

 

I was thinking of trying to get a convertor to plug in that will take a standard monitor output and convert it to composite video.. anybody used one?  recon this would work better?

 

thanks

chris

This reply may be a little late, presumably you are running directly

from S-Video out of your laptop to S-Video in of you vision mixer

and are not using any convertors. Secondly I assume you have set

your laptop to output PAL-I (UK PAL) at a low resolution/refresh rate

and your mixer is designed for PAL-I use. It's also worth mentioning

that if you are trying to play DVD videos you could encounter

macrovision technologies. I have found this to be the case even

if I ran certain video players such as PowerDVD.

 

You don't mention how you are displaying your image. Unless I

have misunderstood something, I am assuming you are using

a projector, in which case could you be encountering a video

earth loop? I have had this problem before, it causes a rolling

image along with extreme fuzzyness. IIRC we only resolved it

by running d-sub datacable directly to the projector. Other

suggestions are to try and run the mixer and projector from the

same power source (socket if need be) and to try running the

laptop without a power supply to see if any difference can be found.

 

There are expensive earth removing solutions available but it

may be worth looking at shieled cabling and high quality connections.
