Analog VS DVI

For once and for all, can anyone please tell me the Pro's and Con's of each connection? (Video card to Monitor, that is)

While shopping for a 21" LCD I found the following statement.

Due to the bandwidth requirement, there may be an occasional pixel dropout. Recommend 1600 x 1200 resolution use Analog input (Samsung 210T)

I've always thought DVI is superior to Analog, but apparently it's not so in this case. And I realized I didn't actually know anything about those different technologies. Can anyone care to explain (or a link or two)?

 
i am not sure about this. the predecessor for DVI was called DFP. and that had 1 bandwith channel instead of DVI's 2 channels (DFP was maximum 1280x960).



i mean all you need is picture and color information for all the pixels on the LCD at whatever refresh rate.



so like if you have 1600x1200 pixels and need to send a 24bit value at 60hz.


DFP was plenty for 1280x960, which is approximately 1.3 x 3 bytes x 60 times a second at 60hz . now 1600x1200 is 2 x 3 x 60. so its not even twice as much, yet dvi has twice the bandwith.
