My computer doesn't support 4 displays using MSTDP124DP. How can I add more displays?

We recommend using USB video adapters when an MST hub isn’t an option. They can work around the display limitations of the GPU. Plus, they are easy to install and USB 3.0 versions perform very well. Examples: USB32HDES, USB32DP24K60.
