I hope that two monitor is better than one.
I use a dual monitor with one notebook computers and a monitor at a part-time job.
So, I want to use a dual monitor in my home, too.

After I thought that, I went to a “LABI” store.
I gave sales-person a question.

“You are trying to do the impossible.”

“Notebook computers cannot input a display but output.
So, you cannot used a dual monitors with two notebook computers”
“(ー.ー ;) ”

Soon after, I left from this store and returned my home......
