I do furniture design work both in my home office and in my shop. I want to have access to all my desktop programs on my 1st floor pc when I go down to the basement to make furniture. I have found hardware (monoprice.com) that will let me extend monitors over CAT5/6 to my shop and these devices work. I have three monitors and want to use them in this scenario:

1st floor: 24” Dell 2405 1920 x 1200, DVI
1st floor: 19” Samsung 191T 1280 x 1024 DVI

Basement: Sony 19” 1280 x 1024 VGA only

I have two video cards, Quadro FX 580 (dual DVI) and Nvidia 7600GT ( DVI and VGA)
When upstairs I have the 24” as primary (on the FX580 card), the Samsung as secondary (on the 7600GT card), and the Sony downstairs cloned off the 7600GT card.

I have played with windows mgmt. software to switch the Sony to primary when I go downstairs, but depending on where I have programs open, I can get messed up. Then when I go back upstairs I need to re-establish the Dell as primary.

Is there a way DisplayFusionPro (just bought and experimenting with the software) can do this for me? Or do I have to “bite the bullet” and have dual displays in both locations. Note that to clone a monitor they must be the same resolution, and on the same video card, so I would have to spring for a 1920 x 1200 extra monitor or (sadly) replace my Dell and move down to the more ubiquitous 1920 x 1080 standard.

Thanks for your help and a great product.

Tried it out and got it to work fine. For a while when I switched back to my office set up with two monitors, the desktop icons stayed on the 2nd monitor, not primary. But somehow it got sorted out so I am in business.

Thank you for your help and your continued development of the product!
