OT HDW question

[Michael Butash]

It's essentially analog vs. digital - more bandwidth, less interference, 
no error detection/correction, etc.  Probably not an issue still if 
you're using *good* cables, but you just want to make sure no emi source 
near will cause picture issues - not/shouldn't be an issue with dvi.

Quick google found this:

DVI is the first digital standard and supports a dual link mode, which 
allows res up to 2048 x 1536 and beyond. The DVI specification supports 
hot plug and play display devices.

There are 3 main different configurations when it comes to DVI:
1. DVI-A is designed for analogue only connections
2. DVI-D is designed for digital signals only
3. DVI-I (Integrated) is a single connector which is designed for both 
digital and analogue use, and is backward compatible with analogue displays.

Most LCD monitors that support digital signal have DVD-D connectors.

The cables: DVI-I single link configuration provides bandwidth 
sufficient for res up to 1600 x 1200 and high speed transmission up to 
4.95Gbps.
DVI-I dual link config can do 2048 x 1536 @ 9.9Gbps, this is the same 
for a DVI-D dual link configuration.
