How To Use Laptop as Monitor and Keyboard for Desktop

Having an additional monitor for work is a huge time-saver since you no longer have to switch between Microsoft Word and Google Chrome. Choosing which window to put at the top is no more essential. While not in use, you may utilize the second screen as a media display, which is another benefit of having several monitors set up simultaneously.

An extra laptop may be used as a “second screen” in the absence of an additional display.

Traditional KVM switches are no longer required, thanks in part to the proliferation of KVM applications!
