TwomonUSB is a program that allows you to use your iPhone or iPad as an extended monitor for your PC. Developed by DEVGURU Co. Ltd., this software offers a convenient way to connect your smart device and computer to create a dual monitor setup.

One of the key features of TwomonUSB is its stability. Unlike other similar programs, TwomonUSB is not affected by network connectivity, ensuring a stable and reliable experience. Additionally, it provides a fast video playback with a maximum of 60 frames per second, resulting in a smooth display output.

Before using TwomonUSB, it is important to note that you need to have the PC program and iTunes installed on your computer. There are also specific requirements for the app to run properly, such as having Windows 7 or later with multiple system displays and connected monitors, using a USB monitor with DisplayLink driver, or installing the Windows OS environment on a virtual machine.

To use TwomonUSB as the main monitor, you will need to set it to directly move to the desktop when you boot your computer. This may require deleting the password or enabling "automatic login."
