I like the idea of stacking or even having three monitors. But I only have two ports coming out of the PC. By adding a video card, I only substitute the original two ports on the motherboard for the ones on the video card. And actually, if you install a video card you do potentially have to take memory from your PC to run the cards (despite the vid card having its own memory), so this can slow your system. Currently, I have the following: 1. Samsung 245BW, 24 inch (can rotate, but currently set at horizontal) 2. Samsung 204T, 20 inch rotates vertical. Here's a front view. Imagine a DVI and VGA port coming out of the back. How do I get three monitors on my desk? Or even better stack them (assuming I cant get a rack) and still have them all run through my two video outputs (1 VGA and 1 DVI)? Thanks.
