I suspect I know the answer, but thought I'd check here.

My new build for a colleague has a 280NVS Quadro video card that supports multiple monitors using a DMS-59 splitter. I'm using one on my machine right now, driving an HP2035 LCD. My card came with both a DMS-59 to dual DVI (which I use) and DMS-59 to dual VGA splitters. The new build's card came with only the VGA splitter, but I have a spare VGA to DVI adapter that lets me use a DVI cable into the same model monitor (this is starting to make me dizzy). I haven't set up the monitor yet, since I'm still shaking down the build on the bench...

So what I want to know is: will going from DVI to VGA to DVI through the various adapters degrade the video to VGA quality? Or will it pass through and wind up DVI, which is so much better? Yeah, I could lug the monitor over and try it out, but I thought I'd ask here in case anyone knows for sure before I order a DVI splitter for $15. Thanks....

When you use a dvi-vga adaptor there is never any digital signal of any kind. The adaptor just connects the right pins to eachother on the vga plug. So doing what you were saying would result in an analog signal, as would a vga to dvi convertor.
