However in a pinch you could telnet, VNC or use some other software over some link connection. But most want the old video cable connection which for 99.99% or more laptops, is not an option.
I recently built a computer, but I didn't buy a monitor for it. I was wondering if it was possible to connect my computer to my laptop so that my laptop works as a monitor. Is there a cable I can buy or something else I have to do? Someone told me to connect them via Ethernet cable but I don't know if that will work.
