I am using a Mac mini with Mojave 10.14.3 and connecting with remote desktop via Citrix Workspace 19.1.0.8. In the remote desktop settings, I have selected Use all my monitors for the remote session. I log into my work computer from my Mac at home and can only use my left monitor. I open a browse. Mac Multi-Monitor DualHead2Go and TripleHead2Go are external multi-monitor adapters. These small boxes attach to the video output of your notebook or desktop computer and let you connect two or three monitors or projectors to your system. Use multiple displays with your Mac. You may be able to connect more than one display to your Mac. To do so, you need a video cable for each display. You might also need an adapter. After you connect the displays to your Mac, you can choose whether to use them as an extended desktop or for video mirroring. Higher resolution means more than just a better-quality image. With a Retina 6K display, Pro Display XDR gives you nearly 40 percent more screen real estate than a 5K display. While most displays max out at around 150 pixels per inch (ppi), our Retina display has 218.
You can connect up to 12 displays to your Mac Pro depending on the graphics cards installed. To find out which ports to use to connect your displays, choose your graphics card:
- Use the Radeon Pro W5700X MPX Module with your Mac Pro.
Connect displays to the Thunderbolt 3 ports on your Mac Pro
You can connect displays to the HDMI and Thunderbolt 3 ports on your Mac Pro and Radeon Pro MPX Module. Learn about adapters for the Thunderbolt 3 ports on your Mac.
To use the Thunderbolt 3 ports on the top* and back of your Mac Pro to connect displays, you must have at least one Radeon Pro MPX Module installed. If a Radeon Pro MPX Module isn't installed, the Thunderbolt 3 ports on your Mac Pro can be used only for data and power.

When you start up your Mac Pro, one connected display initially illuminates. Any additional displays illuminate after your Mac is finished starting up. If one or more displays don't illuminate after startup completes, make sure your displays and any display adapters are connected properly.
If you use Boot Camp and install a third-party graphics card from AMD, you may need to use different AMD drivers in Windows.
