Software to use another laptop’s display as a second monitor?

Anyone know of a piece of software that will let me use my MacBook’s display as a second screen?

I’m well aware that it won’t be the most responsive solution, but I figure static content shouldn’t be an issue.

 

Interesting idea, but I'd be quite surprised if such software existed.

 

There are a handful of apps that make it possible to use an iPad or Android tablet as a second screen, but I find it hard to find something that uses a MacBook screen when connected to a Windows system. The free solution is apparently built in Windows 7 and beyond, but I would rather get a Mac/Windows compatible app.

The closest thing that I’ve found is Synergy so far, but this doesn’t necessarily extend the Windows display. I can’t really articulate what it does instead, so here’s the link: https://symless.com/synergy

I suppose this could work at least in theory (can’t test until I actually get my laptop).

 

I'm familiar with Synergy. It just allows one to control multiple devices with one set of mouse and kb.

https://en.wikipedia.org/wiki/Virtual_Network_Computing would be another near miss.

 

Yeah, the only thing I don’t know about Synergy is whether it would be more intensive or less intensive than a theoretical monitor extending app since the second system isn’t Windows.

My ideal dual monitor use case is to keep all messaging on the secondary, and when gaming, a FAQ when needed. For work, it’s nice to keep up an article or two on the other screen to refer to when clobbering a document.

So in theory, it shouldn’t be too taxing. In theory.

 

Not sure what you mean by more or less intensive? Synergy would be less convenient because you obviously couldn't move apps across. You would have more computing resources though.

 

For my use case, I don’t need special software- just a browser and multi platform chat apps. Sure, it’s not as convenient since the keyboard shortcuts don’t always translate.

In the meantime, the search continues.

 

Good luck, but I doubt this exists given the price of monitors these days.

 

@kylera you can try SpaceDesk. It will run in a browser on MacOS.

If your Macbook can act as a Miracast receiver/sink, you can use Windows Connect feature, which is built into Windows 10. It should provide better experience than any third-party solution, at least that was the case when I last checked.

FWIW any reasonably modern Windows 10 machine with a Wi-Fi adapter that isn't complete thrash supports Windows Connect as both host and client.

 

It seems I didn’t read the system requirements closely enough the first time around when I dismissed it; I didn’t realize the secondary machine could support it with a web browser!

Thanks! I’m going to set a reminder to install it some time after my laptop finally lands!
