How to repair my Splashtop dual monitor not working [6 solutions]

Splashtop comes with some screen issues, for example, Splashtop's blank screen not working or dual monitor not working. When you are faced with the dilemma of a dual monitor not working, do you wish there was an easy and quick way to solve this problem? There are six solutions of how to fix my Splashtop dual monitor not working.

Solution 1. Check multiple monitor settings

The first thing you can do is check the multi-monitor settings on your computer and ensure that Splashtop has multiple monitors enabled.

Step 1. Ensure that your Windows/Mac Business App and Splashtop Connector have been updated to the latest versions.

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


Step 5. Then make sure that 2 monitors are displayed, indicating that it recognizes both computers.


If you're using a Mac, go as follows:

Step 1. On a Mac, go to "System Preferences" > "Display"


Step 2. And then make sure that both monitors are recognized.


Once you have made sure that your local monitors are seeing both monitors, then repeat this step for your remote monitors.

Solution 3. Swap out the second monitor cable

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.

Tips: Good cables don't cost a lot of money. Gold-plated connectors and oxygen-free copper do not have any significant difference in image quality. However, poorly constructed cables can cause problems. That's why you are expected to buy cables from a trusted manufacturer.

Solution 4. Restart the computer

One effective method is to restart the computer. By doing this, you can solve the problem in most cases. This is because the monitor may be experiencing a malfunction, or there may be an external program interfering with Splashtop's dual-monitor feature. Once the restart is complete on both the local and remote computers, attempt to establish a connection again and assess whether the problem persists.
