Multi-monitor basics[edit]

Connecting multiple monitors to a computer these days is a common affair. Provided that your computer has the necessary video ports for multiple monitors, the process is pretty straightforward, although it is best performed with monitors of the same physical dimensions and resolutions, as well as a minimal level of bezel for the best experience. Simply connect the additional monitors to the video ports on your computer, position the monitors how you would like, and turn them on. In most cases, your OS will immediately recognize your new monitor.

There are a few things to note about setting up multiple monitors:

  • First you must make sure that your computer can support multiple monitors. Some bargain-bin desktops or laptops may only feature 1 video output, thus not allowing the use of multiple monitors. Physically examine the computer or consult your documentation to see if its possible.
  • Secondly, make sure you have the right connectors. Most AMD/Nvidia graphics cards these days contain some combination of DVI, mini HDMI, and DisplayPort. Make sure that your monitor has a connection for one or more of these connection types, or that you can find a converter.
  • Third, there are multiple ways to set up your desktop on the multiple monitors. You can display the same thing on all displays, extend the desktop across the multiple monitors, or edit each monitors orientation separately. Simple go into the graphics options and see what options are available for you.
  • Fourth, AMD and NVIDIA graphics are not created equally when it comes to multiple monitors. A large majority of Radeon cards with 3+ video connectors will allow for 3+ separate monitors to be connected to it simultaneously, provided you have the right ports/cords/adapters. Earlier Nvidia cards had a hard limit of 2 monitors connected to one card, but you can use three or more monitors from the 600 series on.

Mouse locking[edit]

Certain games do not lock the mouse inside the monitor.[1]

MouseJail[edit]

Dual Monitor Tools[edit]
