docking DVI - real or DAC-ADC?
How does the DVI output port of the advanced replicator port work when there is no DVI output from the notebook itself? I am wondering if it is just converting the analog VGA signal back to digital, or if it is actually able to tap directly into a digital signal from the graphics chip.
I am considering buying the Latitude D610 with the ATI Radeon X300 graphics chip. I see from ATI's specifications that it is DVI compliant, yet there is no DVI output on the notebook. If the port replicator gives me access to the digital signal, I will get a very good picture on an external LCD screen. Otherwise, if the advanced port replicator is just faking it by digitalizing the analog VGA signal, the picture quality will be rather lousy, I suspect.
Does anybody know about this? Maybe someone has experience with picture quality using the port replicator DVI output compared to VGA?
Thanks a lot for any info.

if both monitors are VGA, I would believe that your only solution would be to get another video card (single or dual) and install that in the dock (if there is a place for card expansion).
If a single card - you would hook the 1st monitor up to the doc and second monitor to the card. This would need to be a newer card in my expierence. Old vid cards don't always work well in the expansion area.
Dual card - you could disable the dock card and run both through the newly installed card.
- I ran one DVI cable to the DVI port on the Monitor1, ran vga from dock to monitor2. After that, all I had to do was choose the correct Input for the monitors to match up (DVI-DVI, VGA-VGA). If I remember right, there were 3 buttons on his monitor, and the middle one changed the inputs.
- Here's my scenario...maybe you can give me some ideas on what to try? I've got (2) LCD monitors...both use VGA connectors. I've got the Dell D/600 docking station that has a VGA for my main monitor and it also has a DVI port. I'm trying to figure out a way to utilize both ports from the back of the Docking station in order to have (2) screens working simultaneously. ANy ideas?
- Found a very easy solution!!! I found a USB2.0 to SVGA adapter that works very good! The signal comes right out of the USB port of the Dell D/dock into the connector of the LCD monitor. The cost is $100 and installation was a breeze. The only downfall I can see is that the display uses on-board memory...but my system has 1GB memory so i'm ok. This solution beats the heck out of trying to install a PCI card in this D/dock system. It probably isn't a solution for hi-end users of graphics etc...
