Hi Rod,

 

I’d second what Peter said – I’ve bought a couple of external monitors over the 
last 14 months and both have just connected and worked with both my late 2009 
27” iMac and my new 13” M1 Macbook air. I think the best approach is really to 
just think about:
what sort of display real estate you want/need
what is the resolution of your computer
what is the driving capacity of your computer
 

For myself:
My iMac has a native resolution of 2560x 1440 and simultaneously supports full 
native resolution on the built-in display and up to a 30-inch display (2560 by 
1600 pixels) on an external display
My MacBook Air has a native resolution of 2560 × 1600 and simultaneously 
supports full native resolution on the built-in display and one external 
display with up to 6016x3384 resolution at 60Hz
My Phillips 273v7qdsb has Native Resolution of 1920 x 1080 and HDMI, DVI-D and 
D-sub inputs.
My Lenovo D32qc-20 has Native Resolution of 2560 x 1440 and HDMI and Display 
Port inputs.
 

For my main iMac, I am frequently running multiple Excel spreadsheets and/or 
multiple browser windows with many tabs in each – so my need was for an 
extended desktop to maximise viewing area. Initially I had the Phillips 
attached with a direct mini display port to hdmi cable - which all worked fine 
but I found the discontinuity of tracking from the 2560x1440 iMac screen to the 
1920x1080 monitor screen sufficiently annoying that I ended up reducing the 
iMac resolution to 1920x1080 to match the monitor – which I found much more 
useable. However it seemed a shame to have to resort to downgrading the iMac 
resolution – so, given that the iMac can support video output up to 2560x1600 - 
I decided to upgrade the monitor and bought the 32” Lenovo.

 

As per my previous post, when I initially connected the Lenovo, using the same 
direct mini display port to hdmi cable, I found that the maximum resolution 
that the iMac could see was 1920 x 1080 but I then bought a mini display port 
to display port cable – which unlocked the full 2560 x 1440 resolution of the 
monitor – which now gives a seamless extended desktop of 2x 2560x1440 – which 
works great for me.

 

I now use the Phillips with the MacBook Air at home  - I have a USB-C hub with 
an HDMI port and an HDMI cable to handle the connection and I have the monitor 
set as the main display and the MacBook display just set to mirror the monitor 
– I find the 13” screen hard to view without glasses but the 27” is great.

 

So, as you see, different setups for different purposes – but, if you are 
looking to use an extended desktop with 2 displays/monitors, I do find having 
the same vertical resolution makes for a seamless pointer transition between 
the two screens and avoids the annoyance of the pointer ‘banging into the brick 
wall”.

 

I did see if the Macbook air would drive both the external monitor AND the Luna 
Display connected 27” iMac – but the Luna display app just told me that I had 
reached the display limit of my computer. The Luna Display app obviously makes 
the iMac just look like an external display and, since the MacBook air will 
only drive one external monitor, it is either/or but not both!

 

I’m not sure what size your 2021 MacBook Pro is – the 13” seems to have the 
same capability as my MacBook Air whilst the 14” and 16” obviously have greater 
resolutions AND the ability to drive multiple displays.

 

So, I hope some of that may help your considerations – and there is no need to 
spend $600, or more, on the monitor – I paid $227 for the 27” Full HD Phillips 
and $355 for the 32” curved Lenovo (flat is even cheaper) with 2560 x 1440 
resolution – all at OfficeWorks.

 

Cheers

 

 

Neil

Subject: Re: [WAMUG] External Monitor for MacBook Pro

 

Hi Blitto, I bought a pair of Lenovo 24” regular monitors around 18 months ago 
when I had to work from home due to you know what. I use my Windows work laptop 
but they work equally well on my Macbook by plugging into an HDMI port. Mac OS 
figures out what you’ve got and does a pretty good job of setting up. Sometimes 
a few tweaks needed to get scaling correct, but no fundamental flaws. A lot of 
sellers don’t actually know if they work with Mac OSX, can check on the 
manufacturers site for specifics and compatibility. I’d be surprised if there 
was a monitor for sale now that isn’t compatible. At worst you may have to 
download some drivers off the manufacturer site or wait for Mac OSX to auto get 
the drivers for you.

 

If using multiple external monitors, you might need a third party adaptor to 
have two HDMI ports connect via a single input to the Mac.

 

Regards

 

Pete.

Hi Folks

Please can anyone give recommendations on an external monitor for a 2021 
MacBook Pro?

Can one buy any external monitor (~$600) or does it have to be mac compatible 
(~$1000)?

Thanks

Blitto
