Havingtwo displayshooked up to your computer instead of one can seriously advance your productivity and open up all kind of new options for play , web browsing , and originative tasks — but you do n’t necessarily call for to go out and buy yourself a new monitor . From Apple ’s Sidecar to Google ’s Chromecasting , you ’ve get a choice of wired and wireless options when it comes to getting all sort of screens attach as a 2d exhibit .
And more options are arriving all the time . Applejust announcedUniversal Control for macOS Monterey , which will let you use a individual keyboard and mouse to control multiple Macs and iPads together , just as if they were chain together as display . We ’ll have to wait to test this out , but other demos make it come along unseamed .
allow ’s dive into the options that are usable right now .

In theory , connecting a 2d exhibit to your laptop or desktop should be as simple as connecting a cablegram between the two devices , and if you have a admonisher and a computer that talk nicely to each other — via HDMI , DisplayPort , or Thunderbolt perhaps — then this is exactly what you’re able to do .
In reality , this can be more unmanageable than it needs to be . Even with the instantly placeable , widely supported HDMI criterion there are legion variations to know about . HDMI 2.1 is the latest version , bringing with it features such as 10 K answer support , and the way it ’s been implemented so far has beenless than ideal .
To ensure you ’re getting the best picture potential , you need to ensure that your computing equipment , your video display , and the connecting cable all support the former standard of whatever connection type you ’re using . set out with the output available on your figurer — it ’s deserving checking the spec in as much detail as you’re able to online or via the bundled documentation — and then image it out from there .

Common display protocols like HDMI are to some extent rearwards compatible , though . In other discussion , any laptop computer with an HDMI output will influence with any monitor with an HDMI input — you just might not get the highest resolutions or the fastest refresh rate . Unless you have a particular use case , like gaming or professional photograph - editing work , that wo n’t matter , which makes the frame-up process much more straightforward .
Assuming you ’re not live out to buy a new projection screen and alternatively are look to set up a monitor or television receiver you ’ve already buzz off , you might need to enlist the help of an adapter as well as a connecting cable . A common scenario here would be have got a modern , sleek laptopwith a USB - C portand an previous monitoring machine with an HDMI port . There are plenty of transcriber option , but again duple - check the specs to make certain you ’re working with the right measure and the veracious loop of those touchstone .
There are combinations of calculator and screen that plainly will not act upon together when connected , especially if you ’re trying to do something unusual ( like connect an ancient TV to a brand name unexampled laptop computer ) . That ’s not such a big raft if you ’re trying to use whatever equipment you already have , but it can be really annoying if you ’ve spent a substantial chunk of money . If you are buying new when it comes to your second blind , as we ’ve said , start with the electronic computer output and work from there .

Your other pick is to use a tablet . If you have an iPad and a Mac made in the last few twelvemonth ( see herefor a full list of compatible devices ) , then the construct - in Sidecar feature turns the lozenge into a second screen , either via a cablegram or wirelessly . For the wired pick , you do n’t involve to do much more besides colligate the devices together , make certain they are set to believe each other , then unfold Control Center and get through Display . As we ’ve said , Apple is looking toimprove this functionalitylater this year with Universal Control .
If you require to plow an Android tab into a second screenland , or want to use a Windows personal computer with an iPad , Splashtop Wired XDisplay will do the job for $ 10 ( you’re able to essay it for free first ) . You set up software on both your Windows or macOS computer and on your pill , and the programs take care of all the necessary communication once a connexion has been established . As far as your laptop or background is refer , you ’ve connected a stock subaltern display .
Wireless
Leave behind the restraint of wiring and you’re able to get a bit more creative with how you configure your 2nd screen , though you might not always get such a stable connexion when you go wireless . Depending on what you ’ve already puzzle at the home or office , or what you ’re project to buy , wireless might be the good option for you .
One alternative is a Chromecast . Any screen with an HDMI input can start the streaming dongles , and any computer with Google Chrome installed can shine the screen over to these dongle on a local WLAN meshwork . From Chrome , sink in the three dots menu button ( top right ) , then select Cast — prime Sources and Cast background , then choose your Chromecast from the list .
This only works as a blind mirroring method , so it ’s not like a honest secondary display . However , if you find fault Cast tab instead of Cast desktop then you may have one web browser app tab open on your other screenland while you do everything else on your primary computer . It ’s not perfect , but it works .

If the ironware you have available to you is primarily made by Apple , then an Apple TV box seat can plug into any CRT screen with an HDMI input and turn it into a secondary display for your Mac . This works through the magic of AirPlay : From your Mac , click the AirPlay button on the menu bar ( the arrow pointing into a rectangle ) , and if your Apple TV is on the same wireless fidelity electronic connection it will seem as an choice . Screen mirroring is enabled by default , but to expend the Apple TV as a second display , choice Use As Separate Display from the same AirPlay drop curtain - down menu .
you may habituate Roku machine and Windows computers in a standardised way , using a criterion anticipate Miracast . From Windows , you need to get to the Action Center ( via the speech bubble button on the far right of the taskbar ) , click Project then get in touch to a wireless display , and any compatible Rokus on the local web should seem ( open up the Project menu again to select whether to extend or duplicate the background ) . Newer Rokus alsosupport AirPlaynow as well , leave you another connective choice for Macs .
We refer Apple Sidecar above , which lets you touch base recent iPads to late Macs as secondary displays — this works wirelessly too for supererogatory convenience ( though you might notice a bit more lag ) . Again , start the Control Center from the menu bar , then choose Display . Universal Control in macOS Monterey — where one keyboard and computer mouse can control multiple iPads and Macs as if they were linked displays — will also plump for features like filing cabinet dragging and dropping .

There are several other option out there , although you might be covered by the tools that we ’ve already mention . AirParrotis an splendid third - party software program package that sits on your Windows or macOS motorcar and can wireless extend or mirror your presentation to another calculator , a Chromecast , or an Apple TV . It will set you back $ 16 , but you may try it out for barren .
Then there’sDuet Display , which put to work in a similar means to Sidecar , but supports Windows as well as macOS , and Android as well as iPadOS . It can function with a cable or over wifi , though you ’ll need to yield a $ 20 - per - year subscription fee for the wireless option , on top of the $ 10 up - front cost of the app . If you want the maximum flexibleness with the maximal bit of devices , you might consider it deserving the investing .
