Step 2. In your Business App’s computer list, click on the RDP computers, and then click the gear/information icon.

Step 3. Click "OK" after selecting "Use all my monitors" from the Resolution drop-down option.

Step 4. Connect to computer. During a session, you can choose to view all monitors on one window, or each monitor in its window.

Solution 2. Confirm that the local monitor can recognize both monitors

There is another situation, your local computer may not recognize the two monitors. At this time, you need to confirm it as follows.

Step 1. All non-Splashtop-related apps and windows should be minimized or closed.

Having many other windows and browsers open at the same time may cause you to become confused about the monitor you are using and its location.

Step 2. Use the top hotbar to exit fullscreen in Splashtop

Being in the full screen may blur the clarity of the screen and prevent the remote monitor from being moved and shifted. This may cause applications and other monitors behind them to be hidden.

Step 3. Shrink the remote monitor and try to move it between the boundaries of the local monitor. And make sure you try moving it off on both sides.

Step 4. Open the display settings of your local computer. On a Windows computer right click on the desktop > “Display Settings”

When a monitor exhibits artifacts or no image at all, the most common culprit is a damaged cable. Very long and poorly shielded cables are particularly susceptible to interference.
