Can I use my laptop as a second monitor for my desk computer?
I would like to set up a dual screen display on my pc. Before buying another monitor, I'd like to try doing so with my laptop's screen.
I've got a Lenovo IdeaPad S205, and was hoping to hook my PC to this monitor so as to use the laptop as a monitor. After reading numerous guides on the internet, I learned that a VGA cable is not the way to go since that will not accept input on the laptop.
Are there other alternatives? I have read that it is not possible unless special networking software is used (i've tried it myself but my connection is not fast enough to work in this manner). However, I went to an office a few days ago and saw that most staff were using laptops as secondary monitors to the PCs. And they were all connected by a cable.
Could anyone explain what is needed?
