Twomon USB Customer Insights

1. If it continues to work as intended, I'd say it's well worth the $8.99.It works like a charm (Win 10 + Galaxy View running Android 5.0). The only caveat is that my tablet needs to be plugged into AC power.

2. Second thing I didn't like was there wasn't great instructions or a video to show you how to change settings on a Samsung tablet to allow the app to work.

3. As a plus, if you have a stylus-enabled device, you have greater control of content displayed on the second monitor, or if mirroring screens, can be used like a tablet input, but not as accurately as an actual tablet device.

4. Probably windows detect my tablet as a adapter or something.🤔 Hope it will be fixed in the future.The App does not work with my Samsung galaxy view.

5. They have a mini FAQ for specific devices that have a certain funcionality for gestures and 3-finger-touch, if your device doesn't - than this app is useless.I had a old Samsung tab lying around for a while and it's really awesome that it can use as a second monitor just with data cable.

6. Great work devs!Software does work well for being a second monitor! However it will not alow you to duplicate an additional screen.

7. *** The tablet which I am using is the Galaxy s5e with Android 11 and One UI 3.1.I managed to install, run and connect, although I can't get past the guide as it needs 3 finger touch.

8. This makes it difficult to recommend for using it as a secondary monitor to watch video on whilst gaming, as it causes your frames to drop significantly, depending on the graphical requirements of the game.

9. At any rate, happy with this app, it's been great to use my tablet as a 2nd monitor.This app only works with my least robust computer, so that's a bummer.

10. The GPU usage doesn't scale, meaning, if you lower the resolution displayed on the tablet, the GPU usage still remains high, so I suspect that there could be some tweaking left to do with the PC server.

11. All in all, this is a very nice solution for when you want to be productive on your main display, whilst having some entertainment on your tablet.
