I have been running an olde (AMD 3200!) pc with dual LCD monitors and 
happily printing with profiles & calibration a la Printfix Pro and spyder.

Having just acquired an HP Pavilion dv6500 special edition laptop, I was 
contemplating connecting my main LCD screen to the laptop while using 
the laptop's screen as the secondary monitor.  The laptop has analog and 
HDMI outputs - I was told I could get and HDMI-DVI adaptor to run the 
outboard screen.  Then I can retire the olde beast and run a quicker and 
quieter machine.

While I think it's feasible to do this, and I'm going to give it a try 
in a day or so when the latest project delivers, are there any landmines 
to watch for?  The laptop has an NVIDIA GeForce 8400M GS video card with 
128 meg of RAM, the computer's RAM is 2 gig.  Of course the laptop is 
running Vista, and I'm also concerned about printer drivers - have not 
looked into updates and will do so - I run Epson 2200 and 9800.  My main 
screen is a Viewsonic 21" which is ok for now, some day I'll upgrade that.

Thanks for any hints or help on the subject!
