fixed : how many 4K screens can my M1/M2/M3/M4 Mac handle simultaneously ?

Question :
I have an M3 MacBook that I would like to use with 2 external 4K monitors for my work setup, so I bought an extra 4K monitor, but when I tried to connect it to my MacBook, it didn’t work… What is wrong ?

How many displays can I connect to my M3 MacBook simultaneously ?


Answer :
There are hardware limitations to how many additional screens you can connect to a Silicon (M1/M2/M3/M4) Mac, and they are not the same for the basic M-version, the Pro-version and the Max-version. Actually, it’s quite confusing, because there’s also variation in what you can connect using either Thunderbolt or HDMI. Please find the number of external screens you can connect in the tables below [ warning ! the below may contain typos, do doublecheck on the official Apple website ] :

4K-resolutionover Thunderbolt onlyover Thunderbolt + HDMI
M1+1+1
M1 Pro+3+3
M1 Max+3+4
M2+1+1
M2 Pro+2+2
M2 Max+3+4

M3+2 (but 2nd max. 5K)+2 (but HDMI max. 4K)
M3 Pro+2+2 (but HDMI max. 4K)
M3 Max+3+4 (but HDMI max. 4K)
M4+2+2 (but HDMI max. 4K)
M4 Pro+2+2 (but HDMI max. 4K)

so… generally, all M1/M2/M3/M4 Macs can support at least one external 4K (or even 6K) screen, but if you want connect multiple external screens to your MacBook, you are probably goning to need a multi-monitor-hub, like the BenQ beCreatus DP1310 docking station.

The BenQ beCreatus DP1310 docking station will enable every silicon (M1/M2/M3/M4) MacBook to connect over USB-C to up to 3 external 4K screens (2 over HDMI and the 3rd over DP/DisplayPort).

The regular price of the DP1310 Dock is ca. €300, so check out below if you can get a better price on Amazon [we get a tiny fee if you buy anything using these links, but you will not be paying anything extra] :

fixed : use old iPad as an extra screen for your Mac (or PC)

Question :

Since we are working from home a lot (and the children are home schooling), and we have several old iPads and iPhones lying around gathering dust, we were wondering if it would be possible to use them as second screens on our Macs and Windows PCs to make our work and homework easier by being able to do this (and more) :

  • manage our music playlist (iTunes, Apple Music, Spotify) on our old iPad/iPhone whilst running  MS Office on our Mac/PC without switching apps
  • use our old iPad/iPhone’s touchscreen to put a signature under a PDF-document whilst typing it on our Mac/PC
  • use our old iPad/iPhone as a drawing tablet for our Mac/PC
  • videochat or view an online presentation onour Mac/PC whilst making notes on our old iPad/iPhone using a full-size keyboard (and easily swapping the two around when needed)

We noticed Apple has introduced this great feature called Sidecar that enables you to use your iPad (or iPhone) as a second screen for your Mac. But when I looked at the Sidecar requirements on the Apple website, I found that our older iPads/iPhones aren’t supported.

Is there any way to use Sidecar (or something similar) on our old iPads/iPhones ?

 

Answer :

Yes, even though you cannot use Sidecar on any unsupported iPad, iPhone or Mac, there is an alternative that works just as great for any old iPad (or iPhone) and is not limited to a Mac, but does support Windows PCs also… and best of all : it’s FREE.

This is ideal for working from home and home schooling since you can do all this (and more) :

  • manage your music playlist (iTunes, Apple Music, Spotify) on your iPad whilst running  MS Office on your Mac/PC without switching apps
  • use your iPad/iPhone’s touchscreen to put a signature under a PDF-document whilst typing it on your Mac/PC
  • use your iPad/iPhone as a drawing tablet for your Mac/PC
  • videochat or view an online presentation on my Mac/PC whilst making notes on my iPad/iPhone using a full-size keyboard (and easily swapping the two around when needed)

This FREE alternative for Apple Sidecar is Splashtop Wired XDisplay. It enables you to use any iPad/iPhone running iOS 7 or newer as a second or third (touch)screen for any Mac running OSX 10.9 Mavericks (or PC running Windows 7) or newer.

This means that all these iPhone / iPad / Mac models are supported :

  • iPhone 4 or newer
  • iPad 2 or newer
  • any iPad mini
  • any iPad Air
  • any iPad Pro
  • any aluminum iMac (iMac “Mid 2007” or newer)
  • any iMac Pro
  • Mac mini “Early 2009” or newer
  • Mac Pro “Early 2008” or newer
  • white MacBook “Early 2009” or newer
  • any aluminum MacBook
  • MacBook Air “Late 2008” or newer (2nd gen MacBook Air or newer)
  • MacBook Pro “Mid 2007” or newer

To install, do this :

  • install the Splashtop Wired XDisplay app on you Mac/PC
    • you can download Splashtop Wired XDisplay for Mac or Windows here
  • install iTunes on your PC if you have done so yet
    • you can download iTunes for Windows here
    • on a Mac you don’t need additional software for your iPad/iPhone to be recognized
  • install Splashtop Wired XDisplay on your iPad/iPhone
    • you can download Splashtop Wired XDisplay for iPhone here
    • you can download Splashtop Wired XDisplay for iPad here
  • then, plug your iPad/iPhone’s USB-cable into your Mac/PC
  • then run the Splashtop Wired XDisplay app on your Mac/PC
  • then run the Splashtop Wired XDisplay app on your iPad/iPhone
  • then goto the Settings on your Mac/PC, find the Screen Settings and arrange your screens the way you like
    • you can choose “Mirror Screen” to see exactly the same on your MAc/PC and your iPad/iPhone
    • you can choose “Extend Screen” to arrange the iPad/iPhone as an add-on for your desktop
    • if you already have a second screen attached to your Mac/PC, you can use your iPad/iPhone as an additional third screen also

That’s it !

enjoy 😉
