Superb app. Works like a charm. I'm used to having 2 screens at work, but have to work from home for a few weeks (:-o). I have an old Android tablet and thought I could maybe run it as a small second screen. Et voila! Both my devices are logged in on the same wifi network. For me it was almost as simple as downloading the Spacedesk PC driver application (very fast download, and a lovely, simple application user interface), and installing the tablet app. Connecting tablet to laptop was intuitively easy. I wanted extended, not duplicate screens, which took some fiddling about in Windows display settings once the tablet and laptop apps were connected and talking to each other. It seems to work both wirelessly and via wired USB connection. Very happy. Awesome service for a free app. I also tried a costly alternative app (TwoMon wireless) and it didn't work for me. It messed with the screen settings on my laptop; it was painfully slow to download the PC driver (very bloated, and multiple software components were installed); it was a complete pain to connect the tablet and PC; and I couldn't get it working in extended screen mode. Based on my experience, save yourself bother: go with Spacedesk.

Did not work properly. The additional screen was connected and identified as another screen, but the desktop shown had no windows or content. I tried LAN & USB. Delete, then re-install. Could not resolve the problem. Update: After leaving 1 star feedback, I knew I was doing something wrong as all other users had no problems. I was surprised to get advise from Spacedesk support suggesting what I had done wrong. After making the changes suggested, it all appears to be working. 5 stars

Is your screen set to desktop extension instead of duplication (mirror)? Read instruction manual https://www.spacedesk.net/documentation/ Look at chapter "CONFIGURATION AND SETTINGS"->"Primary Machine"->"Desktop Extension or Desktop Duplication (mirror) Settings...". If this does not help, then support is available on: https://help.spacedesk.net/

Works great. I use it as a third screen for my virtual pinball machine, but it's also great to monitor progress of downloads or renders on the PC from anywhere in the house without having to sit down and turn the screen on.
