Video memory req for 2D apps?

[srps]

Questions:

1. How much video memory is required for 2D apps? I know it is resolution X color depth. Should we multiply this with number of windows/apps open simultaneously as well?
2. Does video memory consumption vary depending on the output mode being used viz., DVI or Analog?

Thanks

1) I don't think you need to consider having multiple high-res 2D apps open at once (unless maybe they're games, which might store various things in the video card's memory, like sprites). The hardware frame buffers are stored on the card, but not any extra window system buffers or the like. Even a 16MB card can handle 32-bit color at 1600x1200 just fine (although you need a 32MB card to double-buffer that in hardware).

2) No.

Thanks Matthias99, for the clarifications.
