TwomonUSB

Works well. You will have one more monitor for lets say observing your OBS recording status.

Has 3 modes which can reduce needed data transfer rate or reduce lag by increasing the transfer rate. Normal mode was enough for me. For a tablet, USB 2.0 connection is enough so dont hesitate or bother about these details. The only possible problem is introducing the device.

I'd recommend you to try and see before buying (apk or trial) since your device needs to have a very compatible windows USB driver as stated in the main page (Apple, Samsung, LG, Lenovo, Google...) Not all of my devices were able to work with USB cable. But when they work its awesome cuz that means you will have a touchscreen access to Windows 10 desktop.

Actually, I didn't use TwomonUSB but EasyCanvas, an app built by the same company. It offers 14 days' trial. At the beginning, it didn't work normally, but after I followed the solution on their website, it began to work! Nearly no lags! And I can also use my Apple Pencil on my PC! It's so unbelievable! In contrast, when I use Duet Display, I can feel very annoying lags(I cannot have the 'Zero lags' experience). I haven't contacted Duet's team, but maybe I will choose EasyCanvas at last. Duet Display charges $19.99 a year, but EasyCanvas only needs a one-time purchase($11.99). Why don't I choose EasyCanvas?

Works well. Just plug and run Twomon on both sides. Since it doesn't need to use the network (and it's able to), its a precious little program solving the problem for all the people.
