Excellent app. Easy to install. Just had to adjust my monitor setup and screen resolution in the display settings on my desktop to get it to mirror my main display. Was up and running in just a couple of minutes. I tried to install a couple other similar apps but got error messages when installing their drivers. Had no problems installing the driver for this app. Works great with Photoshop and my Tab S7+.

Worked flawlessly right "out of the box". As soon as the driver installed on the PC, the android app found and connected. I turned it up to 60 fps and watched a YouTube video. Not perfect but usable. The fonts are a little small, but it's only a 10 inch tablet so that's not a problem with the app. The windows monitor control panel functions, allowing adjustment of the second screen location and even resolution switching, but only native tablet resolution or 800 x 600, with black bars on sides

This app works great. I use it with a 10" Fire tablet. But, I've noticed with version 0.9.80 of the app and 1.0.18 on the PC, that when the screens have turned themselves off after I have been away, the 'Connected-Display OFF' message on the tablet is stationary in the center of the screen, instead of bouncing around randomly like it did before the update. I don't know what the chance of burn-in is, but I don't think I want to find out.
