What is Reddit's opinion of Mouse without Borders?

From 3.5 billion Reddit comments

https://www.microsoft.com/en-us/download/details.aspx?id=35460

>...control up to four computers from a single mouse and keyboard. This means that with Mouse without Borders you can copy text or drag and drop files across computers.

Assuming both machines are windows, there is a program made by Microsoft called Mouse without Borders. I don't remember who but I remember hearing a streamer talk about it before. I have never used it but it might be what you are talking about

Not like this is an actual solution for many- however, if you have a secondary PC (EG. a Streaming rig) in addition to your gaming rig, Mouse Without Borders allows you to setup a classical dual monitor setup, on two separate PCs, with only one input device.

Bit extreme, but I can confirm that it does resolve D2's lock to 30hz when not in focus. (But, Bungie should really allow us to configure this within the CVARS.xml file, like seriously)

If they are on the same network, just use Remote Desktop to log into the second from the main that the USB devices are plugged in to.

You can also use them both at once if you wanted and they are on the same network by using Mouse without Borders.

A small application built by a Dev over at Microsoft and is pure genius.

You can use Duet itself if you have an iPad.

You can also use Microsoft's own Mouse without Borders. It's what I use across two PC's at home.

https://www.microsoft.com/en-us/download/details.aspx?id=35460

In my personal experience I use Mouse without Borders. With a little configuration you can control over 4 Pcs with just one mouse and keyboard and it works like a kvm and best of all It's Free!

Download Microsoft Mouse without Borders from the MS Garage for free. As long as both PCs are on the same network it will work great.

https://www.microsoft.com/en-us/download/details.aspx?id=35460

Software like Share Mouse or Mouse without Borders and there's plenty of others. Just google control multiple computers with one mouse/keyboard and pick your poison :)

While this is a good deal for what it is, I highly recommend "Mouse Without Borders" which functionally does the same thing without a button press and shares copy/paste across the two PCs you're linking. It's also free.

I use it for my media server and gaming rig, works flawlessly.

Check out Mouse Without Borders, it's similar to Synergy but Windows only and free. It's also made by Microsoft which is generally a pretty easy green light from an IT department. I'd recommend downloading a version and keeping it on a pen drive though, as all computers have to be running the same version and you need to do a full reinstall to update.

Maybe try a different route Microsoft Garage Mouse without Borders

It's not a kvm but it will let you mouse your mouse/keyboard between screens. Latency isn't bad with decent network speeds

I sincerely doubt this is possible. Typically signals from all on-board input devices (keyboard, touchpad or indeed touchscreen) are only send to the laptop's mobo with no way of "projecting" them to another device without using very specific software.

One such software is Mouse without Borders, but I'm not sure if those even work with touch input, let alone in a specific program such as Illustrator...

If your laptop isn't powering the other screen, and it looks like it isn't, then you could use something like Mouse Without Borders from Microsoft Garage. It's not the best software of its kind, but it is free, and works well enough. This could clear up some room from your desk by letting you use one mouse/keyboard for both computers. I've used it a good bit.

was looking for the free app, here it is mouse without borders, actually a microsoft app.
The wording on that page helped me find it
https://www.microsoft.com/en-us/download/details.aspx?id=35460

I don't do it anymore, but back when I was 2boxing, I'd just use this Microsoft software, Mouse without borders: https://www.microsoft.com/en-us/download/details.aspx?id=35460

Used it on both Agnarr and Phini.

Could also share your laptop's keyboard & touchpad to control the desktop PC.

• Mouse Without Borders (free)
• Synergy (I don't think it's free anymore)

You may be able to use Mouse Without Borders (Or some similar type of software) to share your mouse between computers.

It uses your network to share your mouse between computers. It could function in the way you want.

I've never used it on a client computer though for gaming, so your mileage may vary.

Chances are what you actually want is Mouse Without Borders, which lets you control your laptop from your regular mouse/keyboard as if it was a third monitor. It's a lot more optimal than using the laptop screen to stream.

Mouse Without Borders is what you're looking for. It requires you be connected to the same local network, but it lets you use the mouse and keyboard of one to control the other.

The correct program is rather hard to find though, I'll see if I can find it for you.

EDIT: I believe this is it, give it a try: https://www.microsoft.com/en-us/download/details.aspx?id=35460

If they are on the same network you can try something like Mouse Without Borders. I had a keyboard and mouse plugged into my Laptop and was able to use it, seamlessly, across 2 computers (laptop and desktop).

https://www.microsoft.com/en-us/download/details.aspx?id=35460

There are other programs out there that do the same thing but MWB is a good place to start and one I have used in the past. The only reason I quit using it was because I kept losing the mouse due to 4 monitors.

Maybe Mouse without Borders will do what you want? It lets you use your keyboard/mouse to control a remote device.

It's not exactly the same as using your laptop as a second display since the desktop isn't sending any video to the laptop. Instead the laptop is doing it's own thing, but you get to control the laptop using your desktop keyboard/mouse.

I would suggest trying Mouse without Borders from the microsoft garage.

Linky here. (It's also available in the windows store I thought.)

It allows you to control a 2nd machine with the same mouse and keyboard, it also allows you to copy+paste text between each other. I think this would allow you to get as close as possible to what you want, as I don't know of a option to exactly what you want to do. (Personally I use it to control my desktop through my surface when I'm watching something on TV through my desktop, it's handy for remote control yet without needing to remote desktop.)

Hey man, happy 2016! I see you have a set of 2 kb/mice, i can recommend the app "Mouse Without borders" from Microsoft, it allows you to control 2 pc with a single set of mouse & kb over the (local) network

Hope this reduces your frustrations :)

I don't really know about hardware solutions though I assume they exist. What I'll say is that you might wanna look at Windows Mouse Without Borders.

I tried this out on my Intel NUC. It worked nice, but for the two days I had it installed, I kept coming back to my system and noticing the process for the software was stuck at 25% CPU (1 thread of 1 core on a Dual Core, 4 thread CPU). Enough to make the little fan on the NUC spin. I'm using Mouse Without Borders form Microsoft now. Seems to work better. https://www.microsoft.com/en-US/Download/details.aspx?id=35460

Look into Mouse Without Borders. It will save you a great deal of effort swapping between setups, lol. You can use one mouse and keyboard for multiple laptops or desktops. Only requirement is Windows and the computers are on the same network.

Yes - but you don't even need bluetooth for this.

You can also do this with software and cut-and-paste between 2 machines while you drag the mouse cursor across. See Microsoft Mouse without Borders

TIL mouse without borders. as the name says, connects keyboard & mouse between up to 4 windows 10 devices.

pakenya juga lumayan simpel ga perlu bikin akun segala. cukup skip setup nya, cocokin security key antar device, klik apply, langsung nongol device lain di dalam app nya

Take a look at Mouse without Borders. This lets you control up to 4 computers without needing a KVM switch. It takes a little bit of configuring, and it can be wonky at times, so that's my disclaimer. And it's free.

If you don't need both screens to be connected to the work laptop while you're using it, you can try this free software: https://www.microsoft.com/en-us/download/details.aspx?id=35460

You may also be able to connect multiple devices to your monitor and switch between them in its menu. Oh, and I'd keep the peripherals connected to your gaming PC to minimize latency.

Sino un KVM como te dijeron pero vas a tener que estar enchufandolo y desenchufandolo de la notebook de todas formas...

Se almeno la tastiera funziona, mi viene in mente di provare a scaricare teamviewer o anydesk per usare lo smartphone come touchpad, oppure per poter scaricare qualche app - che di sicuro c'è - per usare appunto lo smartphone come touchpad senza usare teamviewer. Ma forse se puoi essere più preciso ci potrebbero essere delle soluzioni più immediate. Se può essere utile, c'è la soluzione di Microsoft Garage Mouse without borders per usare mouse e tastiera su più di un computer, come se stessi usando un solo computer con due schermi. Ma tutte queste proposte alla fine hanno bisogno almeno della tastiera

I just use mouse without borders from MS Garage to control both from one machine. Each machine still needs a monitor, but no cables to move, no shortcuts to create, etc.

Mouse without Borders (https://www.microsoft.com/en-us/download/details.aspx?id=35460)

Install on both machines. Connect m&k to gaming PC to eliminate potential input lag. The downside, gaming PC need to run all the time.

Also, I don't think that basic passive USB 2.0 switches add any lag. They are just mechanical switches without electronic as far as I know.

I use Microsoft's "Mouse without Boarders". Works great. you can copy and paste between machines. https://www.microsoft.com/en-us/download/details.aspx?id=35460. You will need to download it on both machines. one will be primary.

Switch KVM.

Tampoco conozco lo que estás haciendo, pero por ahí tmb te puede servir (https://www.microsoft.com/en-us/download/details.aspx?id=35460) .

Oh I see.

The Dock 2 does not have video input capability. I think your best bet to share the monitor across these devices is to retire the old clamp-dock and just have the MS Dock 2 and cable which you can easily switch between all 3 devices.

Also consider using Microsoft Mouse without borders and Miracast projection for added flexibility. With these free tools you could, for example, have the SurfacePro still in the clamp dock but outputting to the monitor wirelessly through the Surface Book using Miracast.

Or you could have one keyboard/mouse control all 3 systems.

There's a tool that I use called "Mouse without Borders" by Microsoft Garage. It allows you to move your mouse / keyboard across from one PC to another (or laptop, etc) simply using your wifi.

Hi. Start with the Microsoft Mouse without borders software

This will get you 80% there for free by enabling drag-and-dropping of files, text and images between the systems using mouse/keyboard, but unfortunately sharing the pen isn't possible.

Anyway, get that setup and use it for a week to see how much your workflows are improved, then come back and I'm sure folks on this forum can help further.

If you want to reduce your mouse count I would recommend Mouse without Borders. This link takes you to an info page (I know it looks like a download page):

Hi - the USB 3.1 port on that motherboard doe NOT pass video. And unfortunately the rear panel on the Asus mainboards only have HDMI/DVI not separate DisplayPort

You may be able to combine a Sunix PCIe board with a reverse HDMI->DP adapter but this is not something I've tested personally and wouldn't recommend it.

Instead I would look to free software solutions to get you 90% of what you want.

1. Keep the printer attached to teh desktop, but share it our over the wi-fi network. Then have the laptop print to it wirelessly,
2. Keep the keyboard mouse/monitor attached to the desktop.
3. Run a second set of monitor cables from the laptop dock station to the monitors and use the monitor on-screen menu system to switch between the inputs as needed.
4. Share the keyboard/mouse across the systems with the "Mouse without borders" software (assuming you're using Windows 10) so you can drag and drop files and text from one PC to the other seamlessly. https://www.microsoft.com/en-us/download/details.aspx?id=35460

Could you run Windows through bootcamp?

> If both machines are Windows machines you can use Mouse Without Borders to just move your mouse and keyboard over to the work laptop as if it was a screen. There are paid alternatives as well with more features which you can easily find via Google if you want more features.

> For streaming the video to the laptop (this might depend on some network compatibility on the desktop, but worth trying) and use it as an actual display wirelessly, go to the laptop and open Settings → System → Click Projecting to this PC. Once set up the desktop will hopefully detect the laptop as a monitor you can project to when you use Windows key + K.

Software is also an option.

"Mouse without Borders (http://aka.ms/mm) is a product that makes you the captain of your computer fleet by allowing you to control up to four computers from a single mouse and keyboard. This means that with Mouse without Borders you can copy text or drag and drop files across computers. "

Hi - consider getting the software mouse without borders from Microsoft

This may be good enough for your scenario since you can simply drag and drop text across systems seamlessly with a single mouse/keyboard.

The holy grail of interop between a Surface and a Desktop doesn't work the way people expect - All you get is the Surface acting as an extra monitor using the built in "Project to PC" feature built into Windows 10.

Expectation: 1. surface screen operates as external screen of the PC 2. surface touch and pen input processed on desktop PC as if the PC had a Wacom digitizer attached 3. I can still do stuff on my Surface independent of the desktop while connected to desktop

Reality: 1. yes but with lag/latency 2. nope 3. nope

Nice setup! Do you use the iPad there much?

You may be able to get rid of the two keyboards and mice with a program called Mouse without Borders https://www.microsoft.com/en-us/download/details.aspx?id=35460

Lets you use one keyboard and mouse to seamlessly move between computers.

I've got an ultra-wide and 2 24 inch monitors. I have two RDP files - one that only uses the ultra-wide, and one that uses all three monitors. Usually I have music or tv playing from side monitors, and I work from the ultra-wide.

Also, check this out - https://www.microsoft.com/en-us/download/details.aspx?id=35460 Pretty nifty.

I have a solution but it is not an ahk based one even if i could imagine using ahk is the right way to go if you want to do thngs exactly as you want.

My practical solution would be to use Mouse without borders ( https://www.microsoft.com/en-us/download/details.aspx?id=35460 ) to connect the screens and the mouse can go easy between the two. This is if you are using 2 different computers, which i think is most likely given what you said, otherwise a simple VGA or HDMI cable can also connect 2 screens if you are using 1 main computer for both screens.

Now if i have to answer your question the way you asked I would have a look at https://www.autohotkey.com/docs/commands/WinGetPos.htm to get windows coordinates and https://www.autohotkey.com/docs/commands/WinMove.htm to move them.

Instead of a KVM as /u/Trixoxic suggested, just use mousewithoutborders it'll let you control up to 4 pc's with one mouse and keyboard. Super simple setup

i used this for a while. use your keyboard, and mouse with multiple computers. Its kind of a pain to set up and when i did it the first time the "simple" instructions on the app wasnt all that simple. It will work tho. There are hardware options to use, to plug in a keyboard and mouse as well. but the mouse without borders is free. just look for some youtube videos on how to set it up and youll be fine.

Check out Mouse Without Borders and you can share your keyboard and mouse between the desktop and laptop without needing a KVM. There are other solutions, but MWB is really easy to set up.

Do you have a display attached to the other computer? Is it running Windows? If so, https://www.microsoft.com/en-us/download/details.aspx?id=35460

It's called Mouse Without Borders, and only sends mouse and keyboard events. Move the mouse to the edge of the screen and bang! Your pointer is on the other PC.

You may want to make changes to the windowed/fullscreen setting in EQ so it stops vanishing upon losing the pointer, but that's it.

I do some CAD on the Pro - its a bit of a stretch with Intel integrated GPU.

On the Book with NVIDIA graphics, performance is quite acceptable and I don't miss my desktop. Long renders still take a while, but day-to-day stuff is just fine and is a serious contender for a full desktop replacement.

With regards to running laptop + desktop side-by-side, you need the Mouse without borders tool. That way you can use one mouse/keyboard to control both and just drag and drop files from one PC to the other. No fuss.

I cant believe the lack of actual knowlage in this sub.

people that say Synergy are correct, but synergy costs money now.

the one or 2 that said "mouse without borders" are correct for a free solution.

that allows 2 computers on the same network to use one mouse and keyboard. like when you move the mouse to the edge of the screen, it will show up on the other computer, you can click and do anything you need to do, even use the computer.

Mouse without Borders - von Microsoft Garage (entwickelt von Truong Do)

mehre Clients inkl. Bildschirm mit nur einer Tastatur & Maus bedienen (inkl. Clipboard)! Ich benutzte es seit etwa 8 Jahren.

P.S. Ich empfehle an die PC's ohne physische Tastatur, zumindest einen Logitech Unifying Empfänger oder irgend ein anderes Eingabegerät (Maus, Keyboard, Controller) anzuschliessen, selbst wenn es in der Ecke liegt, denn ansonsten simuliert das Tool ein eigenes Input Device wodurch der Curser manchmal verschindet oder übergross ist.

I don't have an answer for you but I would highly recommend a program from Microsoft called "mouse without borders", it is basically a software KVM switch that works beautifully and is free. See if it works for you if not then you can go ahead and spend money on a physical one. It uses wifi so if you have a bad network it might not be as useful for you. I don't work for Microsoft or anything, just use it myself and it's been great.

Mouse without borders is software you can use for mouse and keyboard. It's free and Microsoft stands behind it:

Thats until you find full solution to send picture too.

I can connect my new tv over network with my windows 10 pc as second display (connect option in windows 10 taskbar). Maybe you can use that somehow.

I have been using the Microsoft Garage Mouse without Borders for connecting various windows devices. They don't transfer a windows like it does here, so this built-in Windows solution seems to be more seamless, although maybe it's more bandwidth-intensive. Interesting.

Well I would like to recommend you to not to.

The lagging will kill all the joy.

And believe me having two separate sysems is way better than having only one.

​

Anyways, to your question:

There are coupe of ways but the best way that I had used in the past was Mouse without Borders.

I believe in the past it was a separate from microsoft. Anyways now it is being provided with microsoft itself.

I quit using hardware KVM years ago. If you were windows only, I would suggest you check out Mouse without Borders.

Since you need both windows and MacOS, take a look at something like ShareMouse. I personally haven't tested this particular software buy have a friend who loves it.

This is a KVM from Microsoft (Free), there are some others that are better but cost some money.
As Hardware the K780 is exactly what you want, and as mouse maybe check if Logitech MX Master is something for you.

I hope I could help you a little bit

Found the download page on microsoft.com. From the description:

> This means that with Mouse without Borders you can copy text or drag and drop files across computers.

Sounds like exactly what $UML needs.

This wouldn't just be a second screen, but you can control both computers from one keyboard/mouse with Mouse without Borders which might allow you to accomplish something similar to what you want?

Some PCs do not allow video input, only output, I would like at your video card/graphics details/info to see what it is capable of.

As dlwest65 said - Mouse without Borders from Microsoft Garage.

Not only can you share the mouse and keyboard, but you can share the clipboard and drag and drop one file at a time. You can permanently sync them by entering the same key on both systems.

https://www.microsoft.com/en-us/download/details.aspx?id=35460

TBH, I think at the point when you want to output to more than 4 displays, you *may* be better served using multiple PCs and Synergy, or Mouse Without Borders.

Purely from the operational standpoint, that you've got a lot of shit going on, and maybe you want to spread that out a bit.

But those tools are always finnicky in one way or another..

I'll agree with the synergy posts, I used to use it all the time. But I found if both OS's are Windows, that using Mouse Without Borders is much easier to set up.

eh, I have a workflow which works for me. Sounds like you can try MouseWithOutBorders if you want something new. Just don't need more than 4 computers.

Try Microsoft's Mouse Without Borders:

https://www.microsoft.com/en-us/download/details.aspx?id=35460

I saw someone suggesting this in a similar post, I'm checking it out and it's amazing.

One big caveat: It's technically not a second monitor for your PC, but rather using your PC's mouse and keyboard in your Surface. It extends the desktop and has the Surface kinda acting like a second monitor. They keep being two separates PCs, though, can't share windows, open apps, etc, so it might not suit your needs. It does share the clipboard between them if you want.

Also, it's bidirectional, meaning you can also use the Surface's trackpad or keyboard to control your PC. It works awesome.

Or

1. Get a spare laptop.

2. Configure Mouse without borders on both machine.

3. Open your charts on the laptop with no performance impact on your main rig.

4. Sell as Lake Front Property.

5. Profit!

I've been using it for some time & I like it. My only complaint is that it isn't cross platform. Synergy is cross platform, but has it's quirks & hiccups in my experience. Both have low enough latency for gaming.

The others suggested ways to literally use your laptop as a second monitor, but what you might be more interested in is controlling your laptop using a single mouse/keyboard set like a dual monitor setup:

https://www.microsoft.com/en-us/download/details.aspx?id=35460

The advantage over sharing a monitor being more processing power and much more responsive, the disadvantage being sound isn't shared.

There's a piece of software called Synergy that lets you use your mouse and keyboard across multiple devices via software. It works well and is pretty cool. It's paid though, a free version is also available though not as robust and is called "Mouse without Borders" It's by microsoft and even allows you to transfer files between the two devices. Synergy is multi-OS.

https://www.microsoft.com/en-us/download/details.aspx?id=35460

EDIT: MWB also lets you copy and paste text across devices

Forgot to mention that Mouse without Borders ( https://www.microsoft.com/en-us/download/details.aspx?id=35460 ) should allow me to use the laptop from the desktop and plug a mini displayport from the desktop into the laptop.

If I understand you right, you want to be able to use both laptops with a single mouse and keyboard.

I've used Mouse without borders successfully. Try it out and see if that gets you the result you're looking for.

If both devices are windows, you can use the Mouse without Borders utility from Microsoft to treat the two machines as if they're one dual-screen monitor.

It works quite well, very configurable, and keyboard input is automatically routed to the machine that the mouse is on.

Just in case I'm not fully understanding your post, here is what I think would be best for you:

If each computer has its own monitors (whether that be one monitor or more) then all you are needing to do is be able to control all of the computers/servers with one mouse and keyboard. If this is true, then what I think you need is not a switch but some free software. Now, if all of your computers and servers are Windows you can try Microsoft Mouse without borders. This software allows you to use one mouse and keyboard and connect it to any of the four computers and then the mouse will be able to seamlessly move from monitor to monitor and you will even be able to copy and paste from computer to computer and move files across like it was all one computer (just with multiple start menus). It will even let you program where the monitors are so that the mouse will move more seamlessly. And there are plenty more features where that came from. The software is completely free and will work on any windows computer or server going that is Windows XP (Windows Server 2003) or newer.

To Get Mouse Without Borders you can get it from Microsoft's Website by Clicking Here or by clicking the link below.

If you do use Linux and this software will not work for you it is for windows computers only. I haven't been able to find this sort of software for Linux yet.

If you're on Windows check out "mouse with out borders".

https://www.microsoft.com/en-us/download/details.aspx?id=35460

Edit: Oops, just saw windows and Mac. Check out the Logitech MX Master mouse. That connects via blue tooth or a dongle. To switch between the two you just flip it over and flip a switch.

This can work, although the programs will be run off the laptop, not the desktop. You'd likely have to do a full tear-down of the laptop if you wanted to use the screen itself, which also might break something in the process.

White possible in fact. Not in the typical sense of a secondary screen but you can use one mouse and keyboard on two computers with Mouse Without Borders. I use it at work :)

So while you mentioned security issues, the software solution I've used in the past is a product called Mouse Without Borders. It's actually a Microsoft thing. I can't speak to security nor do I think its actively being developed right now but it does do the job. But if there are network barriers, hardware solutions are the way to go.

Well you can use Mouse without borders Desktop version, Surface Version to use your touchscreen as wireless mouse input for your Desktop, or your desktop keyboard and mouse to navigate on to your surface and drag and drop files.

It is more of a power user application though, not really art focused, and I doubt it has any pressure sensing technology.

Also any solution people do find for you will make the pen lag worse, not better.

I use two, sometimes three different PCs for work. Being able to copy/paste across them and my phone is amazing.

And sharing a mouse/keyboard for all of the computers at once. It's something you can already do with Microsoft's Mouse Without Borders.

You can have two inputs to the monitor, and it basically splits them into separate 5:4 displays on the monitor.

When I work from home, I plug my work laptop in and split it with my PC, and use Mouse Without Borders to use the same keyboard and mouse for both computers.

There are programs like DisplayFusion or Power Desk that will let you split the display up even more off a single input.

Check out Mouse Without Borders or Synergy (while the official Synergy website requires payment for downloads, it's still open source, so you can compile it yourself or get legally free binaries here)

There is a windows project called Mouse without borders it is amazing, honestly it feels really eerily futuristic the first time you use it. Not only can you use your mouse and keyboard on your surface, but you can also copy and paste AND drag over files directly from one computer to the other.

It sends all the info through your router, so depending on whether you have a 5ghz band or not you may have some slight lag issues. It's pretty great though. Absolute must for a SP3 power user.

Bummer man... well for free, you could use Mouse without borders to send keyboard and mouse input across, but I don't believe it will play nice with a controller like that.
