I have portable dvd player I would like to use as a VGA or Composite display connection for my carputer. It only has audio and video outputs. Will I have to buy a special controller card OR can I solder VGA/Composite connections to circuit controller already in portable case? I would greatly appreciate website or old thread links. Searching for portable dvd player did not yield interesting results.

they're probably 1/2 res displays so may not be suitable for VGA connection.

They wont be VGA resolution in a portable DVD player unless it is a HD Portable Player, but I very highly doubt that.

So even if you get it working, it will be horribly fuzzy.

To get it working, you need a video controller board. It varies on the LCD screen itself. They range from $100 to $400 for the controller board. You cannot just solder on to the existing chip because all the video converting from digital dvd signal is done on a singal chip most likely. Sometimes they split analogue and digital, so it may be dvd --> optical decoder --> magic analogue chip --> digital decoded optical signal --> magic video driver and dvd decoder --> screen

You can only solder to the input of the video chip. So you would need to take your VGA signal out from the motherboard, then encode it into the proprietary digital signal using some custom hacked hardware, then solder feeds from that into the video decoder chip.

And as I said, even after all that you get a half assed blurry screen that you cannot read text.

Or for $200, you can get a 7" VGA touchscreen.
