Been using Splashtop Wired XDisplay for a couple months now. It’s basically an app that lets you use your Android device as a wireless second monitor for your computer. Pretty solid app if you’re into productivity stuff.
Here’s what you do: you connect your Android to your computer using a USB cable, then you can mirror your computer screen or use the Android as a separate display. There’s also a bunch of customization options – you can choose the resolution, orientation, and stuff like that. And the lag is pretty low, which is important for things like photo editing or watching videos.
Look, if you’re always wishing you had a bigger screen or an extra monitor, you’ll probably like this. It’s not perfect – sometimes the connection can be a bit finicky – but overall it does the job. Worth checking out if you need a little more screen real estate.
