How can I utilize my old Vaio as a dual monitor?

[Castleheart]

I just replaced my old Vaio, model VGC-LV140J, with a new all-in-one, the VPC-L232FX/B.

I want to know how I can utilize my old Vaio as a dual monitor for my newer one. I've tried connecting them both up via HDMI cable, but I wasn't able to configure a new monitor that way. How can I correctly do this?

The old Vaio has Windows Vista, and the new one is running Windows 7. Is this a problem, or is this not significant? Also, the older Vaio has an S-Video input. I mention this because I suspect that I may need an HDMI to S-Vid cable.

Looking very forward to any word from the community.

My deepest appreciation.

It is menttionned in the description of your new VAIO "2 HDMI ports (one for input from a TV or gaming console, one for output to a second monitor)"

Try to connect to the other HDMI port, maybe you tried to connect to the input instead of output

Oh, wow. Thank you for bringing that to my attention. This may mean that my old Vaio has an input and output as well. Going to take a closer look when I get home, and I'll report my success!
