Easy simple gets it done. The best app.doest take up too much of the cpu either and over lan no plugins. Putting my old iPad as a thir monitor.

I tried to use this app for osu and I feel like I got scammed. The app is extremely laggy so I don’t recommend using it for osu.

This has been a game changer when I need more screen space when using my laptop, especially since I’m using the iPad Pro 12.9 as my second display. Highly recommend! So far I have had no issues using it wired or wireless.

Great tool

The app itself is really good and works pretty well with cable and it would be awesome if they added hover detection for iPad’s pen so for digital art you could only look at your monitor

So, I’ve been looking for a way to use my IPad as a tablet for my computer for a while. This program is that! Free for non commercial use, looks like the license is cheap for when I’m ready to buy the commercial license (16 USD), and easy to connect! Sure, setting up its counterpart on the PC was a little confusing, but once set up it’s as easy as opening Spacedesk on the computer and tablet, then connecting. It’s smooth, easy, pretty unlaggy, and allow me to use Blender with my IPad’s touch screen and my Apple Pencil’s pressure sensitivity! Maybe not for everyone, but I sure love it!

There’s a second delay but otherwise works pretty well

Many people need to extend their Mac screen through it as well.

Pretty good if you ask me

This is the first app i found that actually works like sidecar but for Windows and you don’t have to pay anything and it works way better than something like Duet Display. 10/10
Jathan14 • Apr 6, 2026
Best One and I use blender when I tried to zoom in and out I couldn’t so I believe I need a new case with keyboard
Sigy 59 • Apr 1, 2026
Works exceptionally
very silly cat :3 • Mar 18, 2026
i didnt think that this would work but it actually works like a remote desktop and another monitor without wires
Good game Fun and little lag • Feb 27, 2026
IT Good I use this for a few weeks with my iPad Air 4 It work amazing all tho do not recommend For Gameing On your Devices With this I use It for 1080P videos And Watching streams And Haveing Epic Games And Steam On There And I would call it a 3 monitor because Windows Detects it And You can of course Can See And I Am A Tech YouTuber Recomend It AND USE THIS FOR WORK And supports stylus pen And The worst part is it takes a few seconds if you’re connected or wirelessly Bluetooth or Lan or Wi-Fi connected it takes a few minutes or seconds But Wired Is not laggy not hard but the resolution gets on my nerves That it

I wanted to connect my Apple Cinema Display to the garbage Lenovo Thinkpad (which my employer requires me to use). The Lenovo refused to recognize the display. So I wanted to my Mac as an intermediary display, then connect the Mac to the Apple Cinema Display. To this end, I spent a half-hour fighting with a godawful Microsoft product called Windows Remote Desktop - which has since been renamed “Windows App” (the Microsoft Marketing team deserves a gold medal for that exceptional rebranding effort). No success. Then I found Spacedesk and in under one minute, I had the Lenovo screen up on my Mac. And not only does it allow my Mac to serve as a display for the Lenovo, it even allows me to use the Mac to operate the Lenovo, just as if I was using the Lenovo directly. This in itself is a huge win - I can’t avoid the displeasure of having to use the atrocious Windows software, but at least I can avoid the further humiliation of having to use the hardware monstrosity known as the Lenovo Thinkpad. And, of course, I can now view it all on my Apple Cinema Display. Thank you, Spacedesk!

works good, especially if you draw. I cant duplicate the screen anymore though, so it lost most of its useful-ness to me.
MiyaLovesAnime • Feb 8, 2026
Doesn’t work at all, what a waste of time
