FAQ About UPERFECT Δ / Delta Folding Monitors

As the latest folding monitor, UPERFECT Δ / Delta has undoubtedly become the most eye-catching productivity-enhancing partner on the market.

By listing some problems, we can have some understanding of how to solve the problems in advance.

6. How to self-diagnose when the lower screen does not work in the Windows system

Step 1. Check whether the process "Macrosilicon USB Display" exists in the task manager?

If it does not exist, it means that the driver did not start normally. If the driver is not installed correctly, please reinstall it. If it has been installed correctly, please manually find and start it in the system program list. For the problem of driver self-starting, please refer to the solution to the problem of "Windows system driver does not start automatically". Make sure the driver has started normally. If it fails to work properly, please continue to the next step to troubleshoot.

Step 2. Check whether the driver is loaded successfully.
a) Make sure the prototype you are using is connected to the computer;
b) Check in Device Manager to make sure your driver is installed correctly.

The picture above shows that the driver is not installed correctly. Please search and update the driver in the installation directory. The steps are as follows:
1. Right-click (or long press) USB Video;
2. Select "Update Driver";
