Could you explain what equipment is needed to do this? I know it's more then a simple VGA chord. Thank you for the setup for the software, but what hardware is needed?

do your monitors show the same thing? if so, i really really do not see the point of this.

K, here's the deal... I really really need to have a 2nd screen next to my first... I've been wanting to purchase a new PC with the whole thing ready to go, but money it tight, so here's my question: I understand the OS side other things, and setting up the routing/desktop extension. My problem is, there is only one standard VGA monitor out port on my older Dell desktop. I see above about the DVI, but I don't have a port like that on my PC, so wondering if I can convert from either a serial port, or USB, or something to create the 2nd output? I know this: it has the original graphics card still, is that my problem? Can I only use dual monitors if I buy a different graphics card? Any help would be awesome! If you want me to take pic of the rear of the PC, let me know. Thanks so much

Actually there is the newer ati cards do but if you have one with only 2 you can make it three with the onboard graphics port

nkelly777 (author)tinker2342011-05-22

Well you would probably need a graphics card with 3 display ports (rare)
or 2 graphics card

ya I have 2 monitors also. One is vga and the other is dvi. Also for those of you that want to have a seperate background for each screen I use WindowBlinds. It works great as it has a seperate task bar below for each screen and only what's on that screen. So like if I have my browser on my second screen it will only be on the task bar for that screen.

subzero22 (author)subzero222010-09-14

I'm sorry I meant to type Ultramon not windowblinds that's for something else.
