The Scenario
You are not at your office, or don’t currently have access to a second screen. But, wouldn’t it be nice if you could use your Android tablet as a second screen? Depending on your tablet’s make, model, and One UI version, you can! The following video demonstrates my using an Android Galaxy Tab S*+, with a One UI of 6.1 (the minimum is 3.1) as a second monitor with one of my Windows 11 laptops.
What Your Android Tablet Needs
Check your Quick Settings extended settings. Swipe down from the top of the screen, then swipe down a second time to see the extended set of settings. Look for the Second Screen icon and tap it. Your Android screen will change, waiting for you to activate it in Windows.
What to do in Windows
A little counterintuitive, you need to press the Windows key with the letter “K”. Initially, you may be asked how to control the second display (e.g., Duplicate or Extend). I always use Extend so the second screen can be used independently of the first. You may also have to check a checkbox that allows you to use your Windows mouse/keyboard.
What Happens Next
In a few seconds, all things being equal, you’ll see your Windows screen on your Android tablet. Drag & Drop or copy and paste just as if you had another monitor to extend to. Click the link to view the video:

Thank you for your comments! I teach some technical topics to college students, but mainly, technology is a hobby of mine.
Using your Android tablet as a second screen is a brilliant idea, especially when you’re away from your office setup. The step-by-step guide makes it easy to connect your device, even if it feels a bit tricky at first. It’s impressive how seamlessly Windows and Android can work together for extended displays. Have you tested this method with different tablet models or operating systems? What challenges did you face during the setup?

Thanks for your comment and question! Apologies for this late reply. I’ve only tried this method with my current tablet – now three years old (a Samsung Galaxy Tab S8+). To extend displays from one laptop to another, in my experience, requires a different technique or app. Example: I have a Linux box and there’s a way to extend to it, apparently, though I haven’t tried it yet. To extend from Windows to Windows laptops, using either Windows Key + P or + K, I found some pretty flawless software. You need it on both machines, as one acts as a ‘host’. It’s called spacedesk. So far it’s the most reliable.
I found it really interesting how you can use an Android tablet as a second screen for a Windows laptop. The process seems a bit technical, but the step-by-step guide makes it easier to follow. It’s great that this works with One UI versions as low as 3.1, making it accessible to more users. I’m curious, does this method work seamlessly with all Android tablet models or are there specific compatibility issues to consider?

Hi and thank you(!) for your comment and question. My understanding is that screen mirroring to Android (phones or tablets) is more geared to Android’s and One UI’s versions than to how dated the device is. Hope this helps! Sorry for the massive delay in my answer.
