Difference to RAMDAC[edit]

what is the difference with a RAMDAC?78.185.183.73 (talk) 01:39, 18 December 2009 (UTC)mehmet

Not the same thing at all, a RAMDAC is only used to generate three analog signals (for the red green and blue video signals), while also acting as the color palette. That is the digital color signals from video memory input to the RAMDAC got to the address lines of a RAM, in the RAMDAC and the output of the addressed RAM cell go to the input of the DAC. So changing the contents of the RAM changes what color is displayed for each binary value input to the RAMDAC.
Contrary to that a Video Display controller does everything needed to generate a video signal, (horizontal and vertical sync-pulses, and blanking signals, and controls, and reads out, the video memory, so that the right memory locations are sequentially read out and send to a serializer to create a video signal. A Diplay controller may, or may not, also incorporate a palette mechanism, and/or a binary to video signal converter (DAC), but it may also incorporate many other things, like support for "player missiles"/"sprites" and/or bit-blitting functionality.

Video Display ControllerVideo display controller – Please put your reason for moving here. Tony (talk) 14:35, 14 August 2013 (UTC)

I might be wrong, but this is not an architecture or a protocol, but just a component of a larger device—there seems no reason to cap it.

Per WP:MOSCAPS ("Wikipedia avoids unnecessary capitalization") and WP:TITLE, this is a generic, common term, not a propriety or commercial term, so the article title should be downcased. In addition, WP:MOSCAPS says that a compound item should not be upper-cased just because it is abbreviated with caps. Lowercase will match the formatting of related article titles.

  • Support this is clearly a generic term, not a proper noun. W Nowicki (talk) 20:00, 19 August 2013 (UTC)
  • Support per nom. bd2412 T 20:24, 21 August 2013 (UTC)
